What Are the Causes of Elevated Liver Enzymes Levels?
Alanine aminotransferase, or ALT, and aspartate aminotransferase, AST, are the liver enzymes. ALT is mainly found in the liver, while AST is found in the liver and other tissues, organs and cells. These two enzymes are also normally in the bloodstream in small amounts, but are elevated whenever there is damage in the liver cells.
