Albumin (Serum) by Bromocresol Green

What Albumin Does in Your Body

Albumin is a key protein in your blood that helps distribute fluids throughout your body, supports immune defense, and carries important substances like hormones and medications. Low levels may suggest conditions like malnutrition, liver disease, or kidney problems, while high levels could be linked to dehydration or certain medical treatments.

Why Your Doctor Might Order This Test

Doctors may check albumin levels to assess nutritional health, monitor kidney function, evaluate liver disease, or diagnose conditions like edema (fluid retention) or protein-losing disorders. It’s often included in routine blood panels or used alongside other tests for specific concerns.

Common Conditions Affecting Albumin Levels

Low albumin is sometimes seen in chronic kidney disease, liver cirrhosis, severe infections, or poor nutrition (e.g., malabsorption). High albumin can occur in dehydration, certain medications, or after blood transfusions, though this is less common.

What to Expect Before or After the Test

No special preparation is needed for this blood test. You’ll have a small needle inserted into your arm, and a small amount of blood will be drawn. Results are typically available within a few days and may be used alongside other tests for a full picture of your health.
