Serum Albumin by Bromocresol Green Electrophoresis

What Albumin Does in Your Body

Albumin is one of the most abundant proteins in your blood. It helps distribute fluids between your blood vessels and tissues, keeps blood from leaking out, and carries important substances like hormones and medications. Low levels may indicate problems with your liver, kidneys, or malnutrition.

Why Your Doctor Might Order This Test

Doctors may check albumin levels if you have symptoms like swelling (edema), unexplained weight loss, fatigue, or if they suspect liver disease, kidney disease, or severe infections. It’s also used to monitor protein loss in conditions like kidney disease or after surgery.

Common Conditions Affecting Albumin Levels

Low albumin (hypoalbuminemia) can result from liver disease, kidney disease, malnutrition, severe infections, or conditions that cause excessive protein loss (e.g., burns, chronic kidney disease). High albumin levels are less common but may occur in dehydration or certain inflammatory conditions.

What to Expect Before or After the Test

No special preparation is needed for this blood test. You’ll have a small needle inserted to draw blood from a vein in your arm. The process usually takes a few minutes. Results are typically ready within a few days.
