Serum Albumin: normal range & what your result means
Albumin is the main protein in blood, made by the liver. It reflects nutrition, and liver and kidney health.
Typical adult reference range
| Measure | Range |
|---|---|
| Normal | 3.5–5.0 g/dL |
What a HIGH result can mean
- High albumin usually just reflects dehydration
What a LOW result can mean
- Low albumin can indicate liver disease, poor nutrition, inflammation, or protein loss through the kidneys or gut
Ranges vary by lab. Reference ranges are TYPICAL ADULT values and vary by laboratory, age, sex, pregnancy and the method used. Always read your result against the range printed on YOUR report, and let your doctor interpret it alongside your history.
Frequently asked questions
What does low albumin mean?
It can reflect long-standing liver disease, malnutrition, ongoing inflammation, or protein leaking from the kidneys (nephrotic syndrome) or gut. The cause guides treatment.
Is albumin part of the liver function test?
Yes — albumin is included in the LFT, because the liver makes it. A falling albumin can indicate reduced liver synthesis over time.
