Liver function tests can be used to know about the liver functions or liver injury. The most common and widely used liver enzymes tests are the aminotransferases that include aspartate aminotransferase (AST or SGOT) and alanine aminotransferase (ALT or SGPT). These enzymes are normally present within liver cells and to a lesser extent in the muscle cells. If the liver is injured or damaged, the liver cells spill these enzymes into the blood, which causes the SGOT and SGPT enzyme blood levels to rise.
