Blood tests for liver function are used in monitoring the general state of health of the liver. Tests on liver function evaluate the levels of certain enzymes and proteins in your blood. Levels outside of healthy parameters can indicate liver problems. Patients with liver issues may have few, if any, physical symptoms.
Alanine aminotransferase (ALT) is an enzyme found in the liver that helps your body metabolise protein. Like AST, ALT is normally present in blood at low levels. If the liver is injured or damaged, ALT is released from the liver resulting in increased levels of ALT in the bloodstream.
