Liver Function Test
Measures overall liver function.
Description: 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.
Recommended 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 treatment is working
- To measure the degree of scarring (cirrhosis) on the liver
- If you’re experiencing the symptoms of a liver disorder
