What is a normal Albumin level?
A typical reference range is 3.5–5.0 g/dL. Ranges vary between laboratories and can depend on age and sex, so compare your result with the range printed on your own report.
What does a high Albumin level mean?
Dehydration. A single result rarely gives a diagnosis on its own; your doctor will interpret it alongside your symptoms and other tests.
What does a low Albumin level mean?
Liver disease, malnutrition, kidney disease (protein loss), inflammation. Your doctor will interpret it alongside your symptoms and other tests.
About the Liver Panel
Liver tests measure enzymes and proteins made by the liver. Raised levels can point to inflammation or damage, and they are often checked when starting certain medicines.
