Albumin blood test: what your result means
Albumin measures the main blood protein made by the liver. It helps maintain fluid balance and transport molecules.

What does high albumin mean?
Higher values may suggest dehydration or concentrated blood volume. What counts as high depends on the reference range printed on your lab report, because ranges differ between laboratories.
What does low albumin mean?
Lower values may suggest reduced protein production, losses, or inflammation. What counts as low depends on the reference range printed on your lab report, because ranges differ between laboratories.
Albumin units and conversion
Mediki shows albumin in mmol/L. Labs may report it in other units; Mediki converts them automatically so results from different labs line up on one chart.
| Unit on your report | Convert to mmol/L | Convert back |
|---|---|---|
| µmol/L | 1 µmol/L = 0.001 mmol/L | 1 mmol/L = 1,000 µmol/L |
| g/dL, g%, g/100ml | 1 g/dL = 0.1505 mmol/L | 1 mmol/L = 6.646 g/dL |
| g/L, mg/mL | 1 g/L = 0.01505 mmol/L | 1 mmol/L = 66.46 g/L |

Why track albumin over time?
A single albumin result is a snapshot. Comparing it with your earlier tests shows whether a value is stable, slowly drifting, or responding to a change in treatment or lifestyle, which is often more useful than one number on its own.
