Serum or plasma concentration of albumin

Why Is This Test Done?

Doctors order albumin tests to check for conditions that affect fluid balance, such as kidney disease, liver problems, or severe infections. It may also be used to evaluate how well your body is absorbing nutrients, especially in cases of malnutrition or after major surgery.

What to Expect Before the Test

No special preparation is needed for this test. You may have a blood draw from a vein in your arm, or a urine sample may be collected if testing albumin in urine (e.g., for kidney function). If you’re on certain medications or have recent medical conditions, let your doctor know.

What the Results Mean

Albumin levels can vary based on health, diet, and medical conditions. Low albumin may indicate fluid loss, poor nutrition, or organ dysfunction, while very high levels could suggest dehydration or certain liver diseases. Your doctor will interpret results in the context of your overall health.

Common Conditions Affecting Albumin Levels

Low albumin is often linked to kidney disease, liver failure, chronic infections, or malnutrition. High albumin might be seen in dehydration or conditions that reduce fluid in tissues. Always discuss results with your healthcare provider.
