What Albumin Does in Your Body

Albumin is a key protein in your blood that helps keep fluids where they belong—inside your blood vessels. It also plays a role in transporting other substances like hormones and medications. Low albumin can signal conditions like liver disease, kidney problems, or severe infections.

Why It’s Done

A screening test for albumin may be ordered if you have symptoms like swelling (edema), unexplained weight loss, or signs of liver/kidney problems. It can also be part of routine checks for certain medical conditions.

What to Expect Before the Test

No special preparation is needed unless your doctor specifies. You’ll have a small needle inserted into your arm or vein to draw blood. The process takes a few minutes, and you may feel slight discomfort.

What the Results Mean

Results are qualitative (yes/no) rather than a specific number. A positive screening result means your albumin levels may be low, prompting further testing. Your doctor will discuss next steps based on your symptoms and overall health.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
