This test screens for liver inflammation and damage. A liver function test is often given in the following situations:
- to screen for liver infections, such as hepatitis C
- to monitor the side effects of certain medications known to affect the liver
- if you already have a liver disease, to monitor the disease and how well a particular treatment is working
- to measure the degree of scarring (cirrhosis) on the liver
- if you’re experiencing the symptoms of a liver disorder
Measures the overall function of the liver. Commonly used tests to check liver function are the alanine transaminase (ALT), aspartate aminotransferase (AST), albumin, and bilirubin tests. The ALT and AST tests measure enzymes that your liver releases in response to damage or disease. The albumin measures how well the liver creates albumin and the bilirubin tests measure how well the liver creates albumin, a protein, and how well it disposes of bilirubin, a waste product of the blood.
