The Liver Function Test (LFT) is a blood test to measure the function of your liver, and monitor for liver disease. Your liver is a crucial organ for your metabolism. When there is liver damage, there are several proteins that can be measured in the blood to indicate that there is a problem. Some of the tests for liver function include an alanine transaminase (ALT) test, an alkaline phosphatase (ALP) test, albumin and total protein test, an aspartate transaminase (AST) test, bilirubin test, Gamma-glutamyltransferase (GGT) test, L-lactate dehydrogenase (LD) test, as well as a test of your prothrombin time.
