Serum or plasma concentration of albumin by immunoassay (qualitative/quantitative screening)

What Albumin Does in Your Body

Albumin plays a critical role in transporting nutrients, hormones, and medications throughout your body. It also helps regulate blood pressure by controlling fluid in your blood vessels. Low levels may indicate poor nutrition, kidney disease, or severe illness, while high levels can sometimes be linked to dehydration or certain medical conditions.

When You Might Need This Test

Your doctor may order an albumin test if you have symptoms like swelling (edema), unexplained weight loss, fatigue, or if you’re recovering from surgery, illness, or kidney problems. It’s also used in monitoring chronic conditions like liver disease or heart failure.

Common Causes of Abnormal Results

Low albumin levels can result from conditions like malnutrition, kidney disease, liver failure, or chronic inflammation. High levels may occur with dehydration, severe burns, or certain medications. Always discuss your symptoms and medical history with your healthcare provider.

What to Expect During the Test

A blood sample is drawn from a vein in your arm. You may feel a slight pinch, but it usually doesn’t cause discomfort. The test is quick and doesn’t require special preparation, though fasting isn’t necessary.
