Albumin
Albumin is the most abundant protein in the blood, produced by the liver. It maintains pressure in the vessels (retaining fluid) and carries many substances (hormones, medications, calcium). It reflects nutritional status and liver function.
| Rating | Range | What it means |
|---|---|---|
| Talk to a doctor | below 36 g/L | |
| Good | 36 – 48 g/L | Within the reference range. |
| Worth improving | 48 g/L and above |
This marker also has 3 age- or sex-specific range sets in the app — the table shows the general one.
Why it matters
Low with liver issues/diet/inflammation; part of the biological age calculation (PhenoAge).
If it’s low
Low albumin can indicate poorer production (liver disease, malnutrition), loss (kidneys, intestine) or chronic inflammation. With a severe reduction, edema develops.
If it’s high
High albumin is almost always just the result of dehydration (the blood is concentrated), not disease.
What to do
Interpret it in context (liver, kidneys, nutrition, inflammation). Low albumin is often a sign of an underlying condition worth clarifying with a doctor.
