Serum or plasma mass concentration of albumin

Why This Test Is Done

Doctors may order albumin testing to evaluate your body’s ability to retain fluids, check for protein loss (which can happen with kidney or liver disease), or monitor conditions like malnutrition, burns, or chronic inflammation. It’s also used in some medical procedures to determine how well your body is responding to treatment.

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 if plasma is used, it might be collected during a procedure like dialysis. If you’re on certain medications or have recent medical conditions, let your doctor know.

What the Results Mean

Low albumin levels may indicate problems like kidney disease, liver failure, severe infections, or poor nutrition. High levels might suggest dehydration or certain medical treatments. Your doctor will interpret results in the context of your overall health.

Common Conditions Linked to Albumin Levels

Abnormal albumin levels can signal underlying health issues, such as chronic kidney disease, cirrhosis (liver disease), or conditions affecting protein synthesis. It’s also sometimes checked alongside other tests to diagnose or monitor conditions like heart failure or severe infections.
