Serum or plasma concentration of albumin (mass concentration)

Why Albumin Levels Matter

Albumin plays a key role in keeping fluids where they belong in your body and helps transport important substances like hormones and medications. Low levels can signal problems such as poor nutrition, kidney disease, or liver issues, while high levels may indicate dehydration or certain medical conditions.

What Can Affect Albumin Levels?

Several factors can influence albumin levels, including diet (especially protein intake), kidney function, liver health, chronic illnesses like heart failure or diabetes, and certain medications. Stress, infections, or severe illness can also temporarily affect results.

Common Reasons for Testing

Doctors often test albumin levels to diagnose or monitor conditions like malnutrition, kidney disease (such as chronic kidney disease), liver disease, or to assess how well your body is retaining fluids after surgery or illness.

Sample Collection and Preparation

This test typically uses a blood sample drawn from a vein in your arm. The blood is usually separated into serum (liquid after clotting) or plasma (liquid before clotting) for testing. Avoid alcohol or certain medications for a few days before the test if instructed.
