Other common health conditions, such as diabetes, heart disease, pancreatitis, hemolytic anemia and thyroid
disease, can also cause
liver transaminase elevations. Most
liver diseases are characterized by greater ALT elevations than AST elevations except cirrhosis and alcohol abuse. ALT also rises in bile duct obstruction due to stone or tumor. In all liver related cases AST and ALT are pretty high, often double or more than double the normal value.
