Serum or plasma concentration of albumin by nephelometry

What Albumin Does in Your Body

Albumin is a key protein that helps distribute fluids throughout your body, supports blood pressure, and carries important substances like hormones and medications. Low levels may indicate conditions like kidney disease or malnutrition, while high levels could suggest dehydration or liver problems.

How the Test Works

This test uses a nephelometric method to measure albumin concentration in your serum or plasma. Blood is drawn, processed, and analyzed to determine the protein’s level.

When You Might Need This Test

Doctors may order albumin tests to check for kidney function, liver health, malnutrition, or fluid imbalances. It’s often included in routine blood panels or when evaluating symptoms like swelling, fatigue, or unexplained weight loss.

Common Reasons for Testing

Albumin tests are commonly performed if you have symptoms like swelling in your legs, unexplained weight loss, fatigue, or if your doctor suspects conditions like chronic kidney disease, liver disease, or malnutrition.
