Albumin Normal Ranges
Albumin is the most abundant protein in blood plasma, produced exclusively by the liver.
| Age Group | Reference Range | Unit | Notes |
|---|---|---|---|
| Adults (18–64) | 3.5 – 5 | g/dL | — |
Also reported in: g/L.
Critical (Panic) Values
Critical Low: < 2 g/dL. Values outside these limits require immediate clinical attention.
Why Doctors Order the Albumin Test
Low albumin (hypoalbuminemia) is a marker of chronic liver disease, nephrotic syndrome (urinary albumin loss), malnutrition, or severe systemic illness. Because albumin has a half-life of ~20 days, it reflects chronic (not acute) changes in protein synthesis.
How to Enter Your Albumin Result
Albumin can be reported in g/dL or g/L. Choose the unit printed next to your result on the lab report so it is compared with the matching reference range.
What a Low or High Albumin Can Be Associated With
Below the reference range
- Liver disease (cirrhosis, hepatic failure) — reduced synthesis
- Nephrotic syndrome — urinary loss of albumin
- Malnutrition and protein-calorie deficiency
- Inflammatory states (acute phase reaction — albumin is negative acute phase protein)
- Burns (massive protein loss)
Above the reference range
- Dehydration (relative hyperalbuminemia — not true excess)
This interpreter flags a result at or below 2 g/dL as a critical value. Results that extreme are uncommon — contact your doctor promptly, and seek urgent medical care if you feel unwell.
These are common associations, not a diagnosis. A single result is read alongside your symptoms, history and other tests — discuss it with your doctor.
What Can Change Your Albumin Result
Before you read too much into a result, consider whether any of these applied:
- Posture (standing raises albumin by ~5–10%)
- Prolonged tourniquet application (raises albumin)
- Inflammatory conditions (lower albumin as negative acute phase protein)
- Dilution from IV fluids
Preparing for the test: No special preparation. Albumin can be affected by posture (upright position raises albumin slightly due to fluid shift).
Symptoms That Often Prompt Albumin Testing
- Peripheral edema (swelling of ankles and legs)
- Ascites (fluid accumulation in abdomen)
- Pleural effusion (fluid around lungs)
- Fatigue and weakness
- Muscle wasting
