Most health testing starts too late.

You feel unwell. A test is ordered. The result is checked against a lab reference range. If nothing is flagged, you are often told everything is normal

That can be useful. It can also miss a bigger picture.

Most testing today is built around disease. It asks whether a result is clearly abnormal, whether something needs diagnosis, or whether a known condition needs monitoring. That matters. But many people are not only trying to find disease.

They are trying to understand why they feel tired, why their sleep is poor, why they are gaining weight, why their digestion feels off, why their hormones feel different, or whether they are ageing well or what they can do better. 

Health is more than the absence of disease. Long term health is not binary. You are not simply healthy or sick. Health sits on a continuum. Your metabolism, inflammation, hormones, digestion, sleep, stress, recovery and long-term risk can shift for years before disease appears.

A better approach is to ask:

  • What does healthy look like for me?
  • What is optimal for my age, goals, symptoms and lifestyle?
  • What is changing over time?
  • What is my health trajectory?
  • What can I do now to improve it?

That is the purpose of preventative health testing.

Vively’s Baseline Health Check⁠ is built around this idea. It checks 70+ key biomarkers across 10 key health areas, including metabolic health, inflammation, heart health, liver health, kidney health, blood health, thyroid, nutrients and biological age. Your results are reviewed using optimal ranges, not just standard reference ranges, and turned into a personalised plan with support from your Vively health team.

Vively describes the Baseline as a professional health check covering 70+ biomarkers, optimal ranges, biological age and a personalised plan by Vively’s dietitian.

The problem with how health testing is usually done

Traditional health testing is often reactive.

That is not wrong. If you have symptoms, abnormal results or a known medical condition, diagnostic testing is important. A GP should investigate health problems, manage medical conditions and refer to specialists when needed.

When it comes to chronic disease, reactive testing often leaves people in the gap.

That gap is where prevention matters.

A standard test may tell you that your result is inside range. It may not tell you whether your result is optimal for your age, your goals, your symptoms or your future health risk.

The RACGP Red Book describes preventive care as including prevention of chronic disease, early detection of specific disease and health education. It also notes that screening tests should be used where evidence shows benefits outweigh harms. The goal is not random testing. The goal is useful testing that improves decision-making.  

Why reference ranges are not the same as optimal health

Lab reference ranges are useful. They help identify results that may be unusually high or low.

But a reference range is not the same as optimal health.

Reference intervals are commonly based on the spread of results in a reference population, often using the central 95% of values. This means a result can be considered “normal” because it is common in that group, not because it is ideal for a specific person.  

That matters because population health is not the same as optimal health. In Australia, the ABS reported that 81.4% of people had at least one long-term health condition in the 2022 National Health Survey, and 49.9% had at least one chronic condition.  

So if your result is compared with what is common in a broad population, that does not automatically answer the better question:

What does healthy look like for you?

This is where optimal ranges and trends become useful. Optimal ranges are not used to diagnose disease. They help identify patterns that may be worth improving, watching or reviewing in context.

For example:

The goal is not to panic over small variations. The goal is to understand the pattern and take action.

Health is a trajectory, not a snapshot

One test result is a snapshot.

Your health is the trend.

This is one of the biggest shifts in preventative health. A single result can tell you where you are today. Repeated testing and daily tracking can show where you are heading.

A marker can be technically normal but moving in the wrong direction. That can matter more than a result that is slightly outside range but stable and explainable.

This is why Vively is built as an ongoing membership, not a one-off test. Your Baseline Health Check⁠ gives you the starting point. The Vively app tracks meals, workouts, sleep, stress and wearable data. Your nurse and dietitian can use shared clinical context to help you understand what is changing and what to do next.

Start with the question, not the test

The best test depends on what you are trying to understand.

Before choosing a test, start with the question.

Testing should not only be about collecting more data.

It should be about finding the signal that helps you act.

The main types of health tests

Different tests answer different questions.

Blood tests: the best starting point for most people

For most people, blood testing is the best place to start.

Blood tests can show what is happening beneath the surface. They can help identify patterns linked to:

  • energy and fatigue
  • metabolic health
  • Weight management
  • insulin resistance
  • cholesterol and heart health
  • liver health
  • kidney function
  • inflammation
  • thyroid function
  • iron and nutrient status
  • hormones
  • biological age

Vively’s Baseline Health Check⁠ checks 70+ key markers across 10 health areas. It is designed to give you a broad view of your current health, then help you understand what to improve first.  

You can also explore individual markers in the Vively Test Library⁠.

What blood tests can help you understand

Relevant Vively links:

Stool tests: your gut and digestion picture

Stool testing can be useful when digestion, gut symptoms or microbiome patterns are part of the question.

A stool test may help explore:

  • bloating
  • irregular bowel movements
  • digestive discomfort
  • gut inflammation
  • microbiome diversity
  • digestive function
  • possible gut imbalances

Stool testing should be interpreted carefully. The gut is complex, and microbiome testing is not a simple pass or fail result. It is most useful when connected to symptoms, food patterns, stress, sleep and other markers.

For example, fatigue and bloating may relate to gut health. They may also connect with iron, B12, thyroid, inflammation, glucose regulation or stress. The test is only one part of the answer.

Vively’s specialty add-on tests⁠ help members go deeper when symptoms suggest that a broader picture is needed.

Saliva tests: stress, cortisol and selected hormones

Saliva testing can be useful when the question is about cortisol rhythm, stress physiology or selected hormone patterns.

Cortisol changes across the day. A single result may not always show the full rhythm. Saliva testing can sometimes help review patterns linked to morning energy, stress, sleep, recovery and fatigue.

Saliva testing may also be used for selected hormone testing, depending on the panel and clinical context.

The key is interpretation. Hormones are affected by sleep, stress, food, training, alcohol, medication, cycle timing, contraception, illness and life stage. They should not be reviewed in isolation.

Vively’s specialty test options⁠ include deeper testing across areas such as hormones, stress, nutrients, metabolic health and CGM. The Vively test shop includes add-on options such as stress and adrenal function testing, advanced nutrient testing, perimenopause hormone testing, female hormone testing and CGM programs.

CGM: your real-time glucose response

A continuous glucose monitor, or CGM, shows how your glucose changes across the day and night.

Blood tests show your internal baseline. CGM shows how your body responds in real time.

A CGM can help you understand:

  • how meals affect glucose
  • which foods create bigger spikes
  • how exercise changes glucose
  • how sleep affects glucose stability
  • how stress affects glucose
  • whether you crash after meals
  • how quickly glucose returns to baseline
  • why cravings or energy dips may happen

This matters because two people can eat the same meal and have different glucose responses.

Vively’s CGM Program⁠ helps you see how your body responds to meals, movement, sleep and stress. The Vively app connects blood tests, CGM and daily habits into one system, with insights and actions to improve how you feel and age.  

Wearable data: sleep, stress, movement and recovery

Wearables do not replace testing. They explain it.

A blood test might show elevated fasting insulin. A CGM might show glucose spikes after dinner. A wearable might show short sleep, low recovery, high resting heart rate and reduced activity.

Together, that gives a clearer picture.

Wearable data can help track:

  • sleep duration
  • sleep consistency
  • resting heart rate
  • heart rate variability
  • activity
  • workout load
  • recovery
  • fitness trends

Vively connects with wearable and health platforms such as Apple Health, Fitbit, Garmin, Oura and Google Fit, helping bring health data into one place.

Biological age: a broader signal, not a diagnosis

Biological age estimates how your body is ageing compared with your chronological age.

It is not a diagnosis. It is a tracking signal.

Vively’s Baseline Health Check includes biological age and optimal ranges to help members understand how their blood markers connect to long-term health. The value is not just the biological age number. The value is understanding the underlying markers that influence it.

Biological age is useful because it pulls multiple signals into one broader view. Inflammation, glucose regulation, liver health, kidney function and blood health all tell part of the ageing story.

The goal is not to chase a perfect biological age number. The goal is to improve the drivers that shape your health trajectory.

What tests should you get for your goal?

The right test depends on what you want to understand.

If your goal is better energy

Start with blood testing. Useful areas to review include:

  • full blood count
  • ferritin and iron studies
  • B12 and folate
  • vitamin D
  • thyroid markers
  • inflammation
  • liver function
  • kidney function
  • fasting glucose
  • fasting insulin
  • HbA1c

Then add CGM if you suspect meal-related crashes, cravings or blood sugar swings. Add saliva testing if stress, burnout, poor sleep or low morning energy are central. Consider adding a stool test to complete the picture. Optimal gut health is linked with fewer gut symptoms, better nutrient absorption, more stable mood and steadier energy.

If your goal is weight loss or better body composition

Start with blood testing and daily habit tracking. Useful areas to review include:

Then add CGM if you want to understand how meals, timing, exercise, sleep and stress affect glucose.

Wearable data is also useful. Sleep, activity, workout consistency and recovery can affect hunger, cravings, insulin sensitivity and energy.

Related Vively links:

If your goal is better sleep and stress

Start with daily tracking and wearable data. Useful areas to review include:

  • sleep duration
  • sleep consistency
  • resting heart rate
  • HRV
  • training load
  • stress patterns
  • caffeine timing
  • alcohol intake
  • meal timing

Blood testing can help identify contributors such as thyroid issues, inflammation, iron deficiency, B12, vitamin D, glucose regulation and liver health. Then you may try CGM next.

Saliva testing may help if cortisol rhythm is a key question.

Related Vively link:

If your goal is hormone health

Start with symptoms, life stage and timing.

For women, hormone testing depends heavily on cycle timing, contraception, perimenopause symptoms, cycle changes and the question being asked.

Useful areas may include:

  • thyroid markers
  • iron studies
  • vitamin D
  • B12 and folate
  • metabolic markers
  • inflammation
  • oestradiol, progesterone, LH, FSH, testosterone and SHBG where appropriate (prolactin, DHEA)

For men, useful areas may include:

  • total testosterone
  • free testosterone or calculated free testosterone
  • SHBG
  • LH and FSH
  • prolactin
  • DHEA-S where appropriate
  • thyroid
  • metabolic markers
  • liver health
  • inflammation

Hormones should not be interpreted alone. Sleep, stress, alcohol, body composition, medications, surgery and insulin resistance and training load can all affect hormone patterns.

Related Vively links:

If your goal is digestion and gut health

Start with symptoms.

Stool testing may be useful when digestion, bloating, irregular bowel movements, gut inflammation or microbiome patterns are part of the picture.

Blood testing can add context by reviewing inflammation, iron, B12, folate, vitamin D, thyroid, liver health and metabolic markers.

Gut symptoms rarely exist alone. They often connect with stress, food, sleep, hormones, alcohol and medication.

Related Vively links:

  • Specialty Add-On Tests⁠
  • CRP Test⁠
  • Ferritin Test⁠

If your goal is longevity and prevention

Start with a broad baseline. Useful areas to review include:

  • full blood count
  • iron studies
  • lipids and heart risk
  • fasting glucose
  • fasting insulin
  • HbA1c
  • liver function
  • kidney function
  • inflammation
  • thyroid
  • nutrients
  • biological age

Wearable data can help track the daily behaviours that influence those results: sleep, activity, fitness, stress and recovery.

CGM can add another layer by showing how food, exercise, sleep and stress affect glucose.

The goal is not to chase perfect numbers. The goal is to find the highest leverage changes.

Start with:

Which test should you start with?

Why one test is rarely enough

When it comes to long-term health, a single test can be useful. It is rarely the full story.

Your health is a pattern.

Ferritin can be low because of low iron intake, blood loss or absorption issues. It can also rise with inflammation or liver stress.

Fasting glucose can look normal while fasting insulin is already high.

Cholesterol can look like a heart issue, but the deeper pattern may involve insulin resistance, thyroid function, inflammation, body composition or liver health.

Poor sleep can drive glucose instability, cravings, stress hormones and low recovery.

This is why Vively connects multiple data sources in one place.

Your dietitian can understand your results, habits and goals and help you stay accountable to what you value most.

How Vively helps

Vively’s Baseline Health Check⁠ checks 70+ biomarkers across 10 key health areas, including biological age and optimal ranges. Your results are reviewed with a dietitian and connected to your app data, including meals, workouts, sleep, stress and wearables.

Your personalised plan may include nutrition, lifestyle, supplements and further diagnostics where relevant. You can also add specialty tests⁠ when you need deeper insight across areas such as hormones, nutrients, stress, CGM, stool or saliva testing.

Vively’s health intelligence helps turn your data into clearer insights and next steps. It goes beyond asking generic questions in a chat tool. It uses your own test results, habits and trends to help identify what matters most.

The goal is simple: understand what is driving your health, then help you change it.

When to see a doctor

Testing can help you understand your health, but it is not a replacement for medical care.

Speak with a GP or qualified healthcare professional if you have:

  • chest pain
  • shortness of breath
  • fainting
  • unexplained weight loss
  • blood in your stool or urine
  • severe or worsening fatigue
  • persistent fever
  • new neurological symptoms
  • severe abdominal pain
  • very abnormal blood test results
  • known medical conditions that need monitoring
  • pregnancy-related concerns
  • symptoms that are getting worse or are persisting

Vively is designed to support preventative health and health optimisation. It does not replace your GP, emergency care or specialist medical advice.

The simplest way to think about health testing

Do not start with the test.

Start with the question. Then look at the pattern. Then track the trajectory.

If you want a broad starting point, start with blood. If you want to understand glucose in real time, add CGM. If digestion is central, consider stool testing. If stress rhythm or selected hormones are central, consider saliva testing. If sleep, recovery and activity are central, connect wearable data. If long-term prevention matters, track biological age and the markers behind it.

The most useful health test is not the most advanced test.

It is the one that helps you understand what healthy looks like for you, what is changing, and what to do next.

That is the purpose of Vively.

FAQs

What health tests should I get first?

For most people, a comprehensive blood test is the best starting point. It gives a broad view of key systems such as metabolism, inflammation, cholesterol, liver function, kidney function, thyroid, nutrients, blood health and biological age. From there, stool, saliva, CGM or wearable data can add more detail depending on your goals.

Why can my blood test be normal if I still feel unwell?

A normal result usually means your marker sits inside the lab reference range. That does not always mean it is optimal for your age, symptoms, goals or health trajectory. Some early patterns, such as rising fasting insulin, low-normal ferritin or upward-trending liver enzymes, may still be worth improving.

What is the difference between reference ranges and optimal ranges?

Reference ranges usually compare your result to a population range. Optimal ranges help identify where a marker may sit for better energy, metabolism, recovery and long-term prevention. Optimal ranges are not diagnostic thresholds and should be interpreted in context.

Why does Vively look at trends over time?

Health changes over time. A single result is a snapshot. Trends can show whether your markers are improving, worsening or staying stable. This is especially useful for markers like fasting insulin, HbA1c, ferritin, liver enzymes, hs-CRP, vitamin D and cholesterol.

What is the difference between a blood test and a CGM?

A blood test shows your internal baseline at a point in time. A CGM shows how your glucose changes across the day and night. Blood tests can review markers like fasting insulin, HbA1c, cholesterol, liver enzymes and inflammation. CGM can show how meals, sleep, stress and exercise affect your glucose in real time.

Are stool tests worth doing?

Stool tests can be useful when digestion, gut symptoms, microbiome patterns orinflammation are important questions. They are most useful when interpreted with symptoms, diet, medical history and other markers. They should not be treated as a standalone answer.

Are saliva hormone tests useful?

Saliva testing can be useful for certain hormone and cortisol rhythm questions. It should be interpreted carefully because hormones fluctuate and are affected by sleep, stress, cycle timing, medication, training, alcohol and life stage.

What tests should I get for fatigue?

Useful starting points include full blood count, iron studies, ferritin, B12, folate, vitamin D, thyroid markers, inflammation, liver function, kidney function, fasting glucose, fasting insulin and HbA1c. CGM, saliva or stool testing may be useful depending on the pattern of symptoms.

What tests should I get for weight loss?

Useful starting points include fasting insulin, fasting glucose, HbA1c, HOMA-IR, lipids, liver enzymes, thyroid markers, inflammation and vitamin D. CGM can help show how meals, timing, exercise, sleep and stress affect glucose and cravings.

What is biological age testing?

Biological age testing estimates how your body is ageing compared with your chronological age. It is best used as a tracking signal, not a diagnosis. Vively includes biological age as part of the Baseline Health Check, alongside the blood markers that influence the result.

Does Vively replace my GP?

No. Vively does not replace your GP or medical care. Vively helps with preventative health, personalised insights and behaviour change support. You should still see your GP for diagnosis, treatment, prescriptions, urgent symptoms and medical conditions.

What health tests should I get?

Most health testing starts too late.

That can be useful. It can also miss a bigger picture.

Most testing today is built around disease. It asks whether a result is clearly abnormal, whether something needs diagnosis, or whether a known condition needs monitoring. That matters. But many people are not only trying to find disease.

They are trying to understand why they feel tired, why their sleep is poor, why they are gaining weight, why their digestion feels off, why their hormones feel different, or whether they are ageing well or what they can do better. 

Health is more than the absence of disease. Long term health is not binary. You are not simply healthy or sick. Health sits on a continuum. Your metabolism, inflammation, hormones, digestion, sleep, stress, recovery and long-term risk can shift for years before disease appears.

A better approach is to ask:

  • What does healthy look like for me?
  • What is optimal for my age, goals, symptoms and lifestyle?
  • What is changing over time?
  • What is my health trajectory?
  • What can I do now to improve it?

That is the purpose of preventative health testing.

Vively’s Baseline Health Check⁠ is built around this idea. It checks 70+ key biomarkers across 10 key health areas, including metabolic health, inflammation, heart health, liver health, kidney health, blood health, thyroid, nutrients and biological age. Your results are reviewed using optimal ranges, not just standard reference ranges, and turned into a personalised plan with support from your Vively health team.

Vively describes the Baseline as a professional health check covering 70+ biomarkers, optimal ranges, biological age and a personalised plan by Vively’s dietitian.

The problem with how health testing is usually done

Traditional health testing is often reactive.

That is not wrong. If you have symptoms, abnormal results or a known medical condition, diagnostic testing is important. A GP should investigate health problems, manage medical conditions and refer to specialists when needed.

When it comes to chronic disease, reactive testing often leaves people in the gap.

That gap is where prevention matters.

A standard test may tell you that your result is inside range. It may not tell you whether your result is optimal for your age, your goals, your symptoms or your future health risk.

The RACGP Red Book describes preventive care as including prevention of chronic disease, early detection of specific disease and health education. It also notes that screening tests should be used where evidence shows benefits outweigh harms. The goal is not random testing. The goal is useful testing that improves decision-making.  

Why reference ranges are not the same as optimal health

Lab reference ranges are useful. They help identify results that may be unusually high or low.

But a reference range is not the same as optimal health.

Reference intervals are commonly based on the spread of results in a reference population, often using the central 95% of values. This means a result can be considered “normal” because it is common in that group, not because it is ideal for a specific person.  

That matters because population health is not the same as optimal health. In Australia, the ABS reported that 81.4% of people had at least one long-term health condition in the 2022 National Health Survey, and 49.9% had at least one chronic condition.  

So if your result is compared with what is common in a broad population, that does not automatically answer the better question:

What does healthy look like for you?

This is where optimal ranges and trends become useful. Optimal ranges are not used to diagnose disease. They help identify patterns that may be worth improving, watching or reviewing in context.

For example:

The goal is not to panic over small variations. The goal is to understand the pattern and take action.

Health is a trajectory, not a snapshot

One test result is a snapshot.

Your health is the trend.

This is one of the biggest shifts in preventative health. A single result can tell you where you are today. Repeated testing and daily tracking can show where you are heading.

A marker can be technically normal but moving in the wrong direction. That can matter more than a result that is slightly outside range but stable and explainable.

This is why Vively is built as an ongoing membership, not a one-off test. Your Baseline Health Check⁠ gives you the starting point. The Vively app tracks meals, workouts, sleep, stress and wearable data. Your nurse and dietitian can use shared clinical context to help you understand what is changing and what to do next.

Start with the question, not the test

The best test depends on what you are trying to understand.

Before choosing a test, start with the question.

Testing should not only be about collecting more data.

It should be about finding the signal that helps you act.

The main types of health tests

Different tests answer different questions.

Blood tests: the best starting point for most people

For most people, blood testing is the best place to start.

Blood tests can show what is happening beneath the surface. They can help identify patterns linked to:

  • energy and fatigue
  • metabolic health
  • Weight management
  • insulin resistance
  • cholesterol and heart health
  • liver health
  • kidney function
  • inflammation
  • thyroid function
  • iron and nutrient status
  • hormones
  • biological age

Vively’s Baseline Health Check⁠ checks 70+ key markers across 10 health areas. It is designed to give you a broad view of your current health, then help you understand what to improve first.  

You can also explore individual markers in the Vively Test Library⁠.

What blood tests can help you understand

Relevant Vively links:

Stool tests: your gut and digestion picture

Stool testing can be useful when digestion, gut symptoms or microbiome patterns are part of the question.

A stool test may help explore:

  • bloating
  • irregular bowel movements
  • digestive discomfort
  • gut inflammation
  • microbiome diversity
  • digestive function
  • possible gut imbalances

Stool testing should be interpreted carefully. The gut is complex, and microbiome testing is not a simple pass or fail result. It is most useful when connected to symptoms, food patterns, stress, sleep and other markers.

For example, fatigue and bloating may relate to gut health. They may also connect with iron, B12, thyroid, inflammation, glucose regulation or stress. The test is only one part of the answer.

Vively’s specialty add-on tests⁠ help members go deeper when symptoms suggest that a broader picture is needed.

Saliva tests: stress, cortisol and selected hormones

Saliva testing can be useful when the question is about cortisol rhythm, stress physiology or selected hormone patterns.

Cortisol changes across the day. A single result may not always show the full rhythm. Saliva testing can sometimes help review patterns linked to morning energy, stress, sleep, recovery and fatigue.

Saliva testing may also be used for selected hormone testing, depending on the panel and clinical context.

The key is interpretation. Hormones are affected by sleep, stress, food, training, alcohol, medication, cycle timing, contraception, illness and life stage. They should not be reviewed in isolation.

Vively’s specialty test options⁠ include deeper testing across areas such as hormones, stress, nutrients, metabolic health and CGM. The Vively test shop includes add-on options such as stress and adrenal function testing, advanced nutrient testing, perimenopause hormone testing, female hormone testing and CGM programs.

CGM: your real-time glucose response

A continuous glucose monitor, or CGM, shows how your glucose changes across the day and night.

Blood tests show your internal baseline. CGM shows how your body responds in real time.

A CGM can help you understand:

  • how meals affect glucose
  • which foods create bigger spikes
  • how exercise changes glucose
  • how sleep affects glucose stability
  • how stress affects glucose
  • whether you crash after meals
  • how quickly glucose returns to baseline
  • why cravings or energy dips may happen

This matters because two people can eat the same meal and have different glucose responses.

Vively’s CGM Program⁠ helps you see how your body responds to meals, movement, sleep and stress. The Vively app connects blood tests, CGM and daily habits into one system, with insights and actions to improve how you feel and age.  

Wearable data: sleep, stress, movement and recovery

Wearables do not replace testing. They explain it.

A blood test might show elevated fasting insulin. A CGM might show glucose spikes after dinner. A wearable might show short sleep, low recovery, high resting heart rate and reduced activity.

Together, that gives a clearer picture.

Wearable data can help track:

  • sleep duration
  • sleep consistency
  • resting heart rate
  • heart rate variability
  • activity
  • workout load
  • recovery
  • fitness trends

Vively connects with wearable and health platforms such as Apple Health, Fitbit, Garmin, Oura and Google Fit, helping bring health data into one place.

Biological age: a broader signal, not a diagnosis

Biological age estimates how your body is ageing compared with your chronological age.

It is not a diagnosis. It is a tracking signal.

Vively’s Baseline Health Check includes biological age and optimal ranges to help members understand how their blood markers connect to long-term health. The value is not just the biological age number. The value is understanding the underlying markers that influence it.

Biological age is useful because it pulls multiple signals into one broader view. Inflammation, glucose regulation, liver health, kidney function and blood health all tell part of the ageing story.

The goal is not to chase a perfect biological age number. The goal is to improve the drivers that shape your health trajectory.

What tests should you get for your goal?

The right test depends on what you want to understand.

If your goal is better energy

Start with blood testing. Useful areas to review include:

  • full blood count
  • ferritin and iron studies
  • B12 and folate
  • vitamin D
  • thyroid markers
  • inflammation
  • liver function
  • kidney function
  • fasting glucose
  • fasting insulin
  • HbA1c

Then add CGM if you suspect meal-related crashes, cravings or blood sugar swings. Add saliva testing if stress, burnout, poor sleep or low morning energy are central. Consider adding a stool test to complete the picture. Optimal gut health is linked with fewer gut symptoms, better nutrient absorption, more stable mood and steadier energy.

  • caffeine timing
  • alcohol intake
  • meal timing

Blood testing can help identify contributors such as thyroid issues, inflammation, iron deficiency, B12, vitamin D, glucose regulation and liver health. Then you may try CGM next.

Saliva testing may help if cortisol rhythm is a key question.

If your goal is hormone health

Start with symptoms, life stage and timing.

For women, hormone testing depends heavily on cycle timing, contraception, perimenopause symptoms, cycle changes and the question being asked.

Useful areas may include:

  • thyroid markers
  • iron studies
  • vitamin D
  • B12 and folate
  • metabolic markers
  • inflammation
  • oestradiol, progesterone, LH, FSH, testosterone and SHBG where appropriate (prolactin, DHEA)

For men, useful areas may include:

  • total testosterone
  • free testosterone or calculated free testosterone
  • SHBG
  • LH and FSH
  • prolactin
  • DHEA-S where appropriate
  • thyroid
  • metabolic markers
  • liver health
  • inflammation

Hormones should not be interpreted alone. Sleep, stress, alcohol, body composition, medications, surgery and insulin resistance and training load can all affect hormone patterns.

If your goal is digestion and gut health

Start with symptoms.

Stool testing may be useful when digestion, bloating, irregular bowel movements, gut inflammation or microbiome patterns are part of the picture.

  • Ferritin Test⁠

If your goal is longevity and prevention

Start with a broad baseline. Useful areas to review include:

  • full blood count
  • iron studies
  • lipids and heart risk
  • fasting glucose
  • fasting insulin
  • HbA1c
  • liver function
  • kidney function
  • inflammation
  • thyroid
  • nutrients
  • biological age

Wearable data can help track the daily behaviours that influence those results: sleep, activity, fitness, stress and recovery.

CGM can add another layer by showing how food, exercise, sleep and stress affect glucose.

The goal is not to chase perfect numbers. The goal is to find the highest leverage changes.

Which test should you start with?

Why one test is rarely enough

When it comes to long-term health, a single test can be useful. It is rarely the full story.

Your health is a pattern.

Ferritin can be low because of low iron intake, blood loss or absorption issues. It can also rise with inflammation or liver stress.

Fasting glucose can look normal while fasting insulin is already high.

Cholesterol can look like a heart issue, but the deeper pattern may involve insulin resistance, thyroid function, inflammation, body composition or liver health.

Poor sleep can drive glucose instability, cravings, stress hormones and low recovery.

This is why Vively connects multiple data sources in one place.

Your dietitian can understand your results, habits and goals and help you stay accountable to what you value most.

How Vively helps

Vively’s Baseline Health Check⁠ checks 70+ biomarkers across 10 key health areas, including biological age and optimal ranges. Your results are reviewed with a dietitian and connected to your app data, including meals, workouts, sleep, stress and wearables.

Your personalised plan may include nutrition, lifestyle, supplements and further diagnostics where relevant. You can also add specialty tests⁠ when you need deeper insight across areas such as hormones, nutrients, stress, CGM, stool or saliva testing.

Vively’s health intelligence helps turn your data into clearer insights and next steps. It goes beyond asking generic questions in a chat tool. It uses your own test results, habits and trends to help identify what matters most.

The goal is simple: understand what is driving your health, then help you change it.

When to see a doctor

Testing can help you understand your health, but it is not a replacement for medical care.

Speak with a GP or qualified healthcare professional if you have:

  • chest pain
  • shortness of breath
  • fainting
  • unexplained weight loss
  • blood in your stool or urine
  • severe or worsening fatigue
  • persistent fever
  • new neurological symptoms
  • severe abdominal pain
  • very abnormal blood test results
  • known medical conditions that need monitoring
  • pregnancy-related concerns
  • symptoms that are getting worse or are persisting

Vively is designed to support preventative health and health optimisation. It does not replace your GP, emergency care or specialist medical advice.

The simplest way to think about health testing

Do not start with the test.

Start with the question. Then look at the pattern. Then track the trajectory.

If you want a broad starting point, start with blood. If you want to understand glucose in real time, add CGM. If digestion is central, consider stool testing. If stress rhythm or selected hormones are central, consider saliva testing. If sleep, recovery and activity are central, connect wearable data. If long-term prevention matters, track biological age and the markers behind it.

The most useful health test is not the most advanced test.

It is the one that helps you understand what healthy looks like for you, what is changing, and what to do next.

That is the purpose of Vively.

FAQs

What health tests should I get first?

For most people, a comprehensive blood test is the best starting point. It gives a broad view of key systems such as metabolism, inflammation, cholesterol, liver function, kidney function, thyroid, nutrients, blood health and biological age. From there, stool, saliva, CGM or wearable data can add more detail depending on your goals.

Why can my blood test be normal if I still feel unwell?

A normal result usually means your marker sits inside the lab reference range. That does not always mean it is optimal for your age, symptoms, goals or health trajectory. Some early patterns, such as rising fasting insulin, low-normal ferritin or upward-trending liver enzymes, may still be worth improving.

What is the difference between reference ranges and optimal ranges?

Reference ranges usually compare your result to a population range. Optimal ranges help identify where a marker may sit for better energy, metabolism, recovery and long-term prevention. Optimal ranges are not diagnostic thresholds and should be interpreted in context.

Why does Vively look at trends over time?

Health changes over time. A single result is a snapshot. Trends can show whether your markers are improving, worsening or staying stable. This is especially useful for markers like fasting insulin, HbA1c, ferritin, liver enzymes, hs-CRP, vitamin D and cholesterol.

What is the difference between a blood test and a CGM?

A blood test shows your internal baseline at a point in time. A CGM shows how your glucose changes across the day and night. Blood tests can review markers like fasting insulin, HbA1c, cholesterol, liver enzymes and inflammation. CGM can show how meals, sleep, stress and exercise affect your glucose in real time.

Are stool tests worth doing?

Stool tests can be useful when digestion, gut symptoms, microbiome patterns orinflammation are important questions. They are most useful when interpreted with symptoms, diet, medical history and other markers. They should not be treated as a standalone answer.

Are saliva hormone tests useful?

Saliva testing can be useful for certain hormone and cortisol rhythm questions. It should be interpreted carefully because hormones fluctuate and are affected by sleep, stress, cycle timing, medication, training, alcohol and life stage.

What tests should I get for fatigue?

Useful starting points include full blood count, iron studies, ferritin, B12, folate, vitamin D, thyroid markers, inflammation, liver function, kidney function, fasting glucose, fasting insulin and HbA1c. CGM, saliva or stool testing may be useful depending on the pattern of symptoms.

What tests should I get for weight loss?

Useful starting points include fasting insulin, fasting glucose, HbA1c, HOMA-IR, lipids, liver enzymes, thyroid markers, inflammation and vitamin D. CGM can help show how meals, timing, exercise, sleep and stress affect glucose and cravings.

What is biological age testing?

Biological age testing estimates how your body is ageing compared with your chronological age. It is best used as a tracking signal, not a diagnosis. Vively includes biological age as part of the Baseline Health Check, alongside the blood markers that influence the result.

Does Vively replace my GP?

No. Vively does not replace your GP or medical care. Vively helps with preventative health, personalised insights and behaviour change support. You should still see your GP for diagnosis, treatment, prescriptions, urgent symptoms and medical conditions.
