Albumin, Serum

Serum albumin measures the most abundant protein in your blood. Albumin is made by your liver and helps keep fluid inside your blood vessels while carrying hormones, vitamins, and medications.

Why it matters

Albumin reflects aspects of your liver function, nutrition, and overall health, and it influences how other results like calcium are interpreted. It's a widely used, informative marker.

If it runs high

A higher albumin is most often due to dehydration rather than a disease. Your clinician will consider your hydration and the rest of your results.

If it runs low

A lower albumin can result from liver or kidney conditions, inflammation, or poor nutrition; it's common in many illnesses and is interpreted in context.

What to aim for

A typical range is roughly 3.5 to 5.0 g/dL. Your clinician can explain your value.
