The albumin test measures the main plasma protein in blood, which is made only by the liver. Practitioners use it to read liver synthetic function, inflammation load and hydration, and to sense-check total calcium, which reads low when albumin is low. Dehydration and long tourniquet time raise it, while recent infection or surgery can keep it low for weeks. Practitioners can order it through the Vively practitioner platform.

What are the Albumin reference and optimal ranges?
| Typical lab reference | Vively optimal | |
|---|---|---|
| Adults | 32 to 50 g/L | 45 to 50 g/L |
Labs differ in method and many set the lower limit at 35 g/L, so read the result against the range printed on the client's report (RCPA guidance). The optimal range is a long-term target, not a diagnostic cut-off.
Check a client's Albumin result
Enter the value from your client's lab report to see where it sits against the typical lab range and the Vively optimal range.
A guide only, not a diagnosis. One result is a starting point: read it with symptoms, history and a repeat test. Labs differ, so check the result against the range on your client's report. Nothing you enter is stored or sent.
How do you arrange Albumin testing through Vively?
- Get verified. Practitioners with a recognised qualification or membership (ATMS, NHAA, ANTA, Dietitians Australia, NSA, CMA or Ahpra registration) can request free practitioner access.
- Choose a panel. Log in to the practitioner platform and pick a panel that includes Albumin, or build your own. It is included in the $99 Baseline Health Check.
- Client collects. Your client collects at a partner collection centre, with their request on their phone or printed.
- Review results. Results come back to you in the practitioner platform, beside your client's other markers, ready for the follow-up consult.

Why does the optimal range sit there?
Our optimal band of 45 to 50 g/L sits at the top of the lab range, because albumin falls with inflammation.
Albumin is a negative acute-phase protein: the liver cuts production during inflammation, so a low-normal value often travels with a raised hs-CRP. Low 40s is common in healthy adults.
A meta-analysis in older adults (Cabrerizo et al., Maturitas 2015) linked albumin in the lower part of the normal range with higher mortality and poorer function. Treat 45 to 50 g/L as a direction to work towards.
Above 50 g/L almost always reflects haemoconcentration. ASPEN (Evans et al., 2021) advises against using albumin as a marker of protein intake.
What should Albumin be read with?
- LowLow albumin, raised hs-CRP
Inflammation or a recent infection is suppressing synthesis; retest once the client is well.
- LowLow albumin, low eGFR or raised creatinine
Possible renal protein loss; a urine albumin to creatinine ratio through the GP is the next step.
- LowLow albumin, raised ALT, GGT or bilirubin
Often seen with chronic liver disease, where synthesis falls after the enzymes change; needs GP review.
- HighHigh albumin with high urea and haemoglobin
Usually haemoconcentration from a dry collection; repeat after normal fluid intake.
What can affect a Albumin result?
- Dehydration, an overnight fast without water, or heavy sweating in the prior 24 hours (raise it)
- Prolonged tourniquet time at collection (raises it)
- Recent infection, surgery or acute illness (can keep it low for several weeks)
- Pregnancy, through plasma volume expansion (lowers it)
- Large fluid intake or IV fluids shortly before collection (dilutes it)
When should you refer the client to their GP?
- Albumin below 30 g/L, or below the lab range on a repeat once the client is well
- Low albumin with oedema, frothy urine, jaundice, ongoing diarrhoea or unexplained weight loss
- Low albumin alongside abnormal liver enzymes or a falling eGFR
- Albumin below about 20 g/L: urgent medical review

Preparing for your Albumin test
- This test doesn't need fasting on its own.
- If your practitioner has requested the Baseline Health Check, fast for 8 to 12 hours before a morning collection (water is fine).
- Drink water as usual beforehand, as being dehydrated can make albumin read higher.
- Take your pathology request to any of 4,000+ collection centres. Bring it printed or on your phone.
- Keep taking prescribed medicines as usual unless your doctor tells you otherwise.
- Results usually take 3 to 5 business days and come to your practitioner. Book your results appointment for after that.
How do practitioners use Albumin with clients?
Read albumin with hs-CRP before making a nutrition call. Where intake is genuinely short, or weight is coming off quickly, protein adequacy and a slower rate of loss are reasonable targets, and the next retest shows whether albumin follows.
Albumin FAQs
Can a naturopath, nutritionist or dietitian order an albumin test through Vively?
Yes. Add it to a client panel on the Vively practitioner platform. It is part of Liver Function Tests in the $99 Baseline Health Check, and is also in Full Body Health Check and Weight Management Test. No account yet? Request free access.
Is albumin a good marker of protein intake?
No, not on its own. Albumin has a half-life of about three weeks and responds far more to inflammation, liver function and fluid status than to diet. ASPEN's 2021 position paper advises against using it to diagnose malnutrition. Use intake history, weight change and hs-CRP alongside it, and treat a low result as a prompt for broader review.
Should I look at corrected calcium when albumin is low?
Yes. About 40% of circulating calcium is protein-bound, mostly to albumin, so a low albumin lowers total calcium without changing the active ionised fraction. Many labs print a corrected calcium for this reason. If corrected calcium is still out of range, that is a separate finding for the client's GP.
Why might a client's albumin be high?
A high albumin is usually haemoconcentration rather than a true excess. Dehydration, an overnight fast without water, heavy sweating in the prior 24 hours and a prolonged tourniquet time all raise it. If urea and haemoglobin are also high, repeat after normal fluid intake before reading anything into it.
How long does inflammation keep albumin low?
Recent infection, surgery or acute illness can keep albumin low for several weeks, consistent with its half-life of about three weeks. Check hs-CRP alongside it: a low albumin with a raised hs-CRP suggests inflammation is suppressing synthesis, so retest once the client is well. If it stays below the lab range on repeat, involve their GP.
