Also Known As: Serum Albumin, ALB

Albumin, a protein produced in the liver, enters the bloodstream, where it helps carry vitamins, enzymes, and other important substances. The protein also helps prevent fluids from leaking out of blood vessels.

An albumin blood test measures the amount of albumin in a blood sample. It can help identify various health conditions, including liver and kidney problems. Albumin may be tested alone or in a panel of measurements such as the comprehensive metabolic panel or liver panel.
