1 The blood tests most frequently used for liver disease are the aminotransferases (alanine aminotransferase or ALT and aspartate aminotransferase or AST). 2  Normal levels of ALT ranges from about 7-56 units/liter, and 10-40units/liters for AST.
Additional tests that may be used to evaluate liver function include 2 1  : Gamma-glutamyl transferase (GGT): This test measures the amount of the enzyme GGT in the blood. 2  Higher than normal levels may indicate liver or bile duct injury.iver function tests (also known as LFTs or LFs) include liver enzyme readings. A single blood sample may include liver function testing for the following 1 1  : Alanine transaminase (ALT): An enzyme that helps metabolize protein.
