Why Is Albumin Tested?
Doctors may order an albumin test to check for conditions like liver disease (such as cirrhosis), kidney disease, malnutrition, or infections. It can also help monitor how well treatments are working for certain conditions.
What Does the Test Involve?
A blood sample is taken from a vein, usually in your arm. The blood is then processed to separate the plasma or serum, where albumin is measured using a specialized lab test.
What to Expect Before the Test
No special preparation is usually needed, but you may be asked to fast for a few hours if your doctor specifies it. Wear comfortable clothing with an easy armhole for the blood draw.
What to Expect During the Test
You’ll sit comfortably while a healthcare provider inserts a small needle into your vein. A small amount of blood is collected into a vial or tube. The process is quick and usually painless, though you might feel a brief pinch.
