Liver Profile

Medically reviewed by Last updated on Oct 3, 2022.

What is a liver profile?

A liver profile is a group of blood tests that show how well your liver is working. The liver makes enzymes and bile that help digest food and gives your body energy. It also removes harmful material from your body, such as alcohol and other chemicals.

What blood tests are part of a liver profile?

  • Liver enzyme tests measure alanine aminotransferase (ALT), alkaline phosphatase (ALP), and aspartate aminotransferase (AST) enzymes. These tests may also include gamma-glutamyl transpeptidase (GGT).
  • Liver protein tests measure albumin and other proteins in your blood. This includes antibodies that help to fight infections.
  • Bilirubin tests measure the amount of bilirubin in your blood. Bilirubin is a yellow fluid made in your body when red blood cells break down.

How do I get ready for the test?

Healthcare providers may tell you not to eat or drink anything, except water, after midnight. Several medicines can affect the results of your liver function tests. Ask your healthcare provider if you should wait to take your medicines until after your blood is taken. Wear a short-sleeved or loose shirt on the day of the test. This will make it easier to draw your blood.

What do abnormal test results mean?

Abnormal levels of liver enzymes, proteins, or bilirubin may be a sign of liver damage or disease. You may need another liver profile or other tests to find the cause of your abnormal test results.
