What is albumin?

Albumin is one of the main proteins in your blood; it is made in the liver. It helps keep fluid inside the blood vessels and plays a role in carrying hormones and some medicines. It is often measured in routine blood chemistry; a single result does not make a diagnosis.

Why might albumin be low?

Low levels can be linked to liver or kidney disease, long-term poor intake or malnutrition, serious infection or inflammation, or protein loss from the gut. Your doctor will consider your history, examination, and other tests such as total protein, liver markers, and kidney markers together.

How is the result interpreted?

Reference ranges vary by lab. One low value does not always mean a serious condition; a mild drop can sometimes be temporary or diet-related. Interpretation and any follow-up tests should be done by your doctor. Looking at albumin next to total protein and the globulin portion can help explain the pattern.

Make sense of your results

If you want to see your blood results in a clear, structured summary, you can run an analysis. Related guides: high or low total protein and globulin results. For diagnosis and treatment, always speak with your doctor.
