The alanine aminotransferase (ALT) test is typically used to detect liver injury. It is often ordered in conjunction with aspartate aminotransferase (AST) or as part of a liver panel to screen for and/or help diagnose liver disease.
AST SGOT â High, Normal, Low (Interpretation) AST is one of the two liver enzymes. it stands for aspartate amino transferase. This enzyme is also known as SGOT, which stands for serum glutamic-oxaloacetic transaminase. AST is a protein that is synthesized in the liver cells. When there is liver complication or damage, this enzyme leaks out and enters the blood stream, something that leads to increased level of this type of protein in blood. AST is also found in other parts of the body apart from liver.
