16412-9Aspartate aminotransferase [Enzymatic activity/volume] in Red Blood CellsActive

Part Description

LP15426-7   Aspartate aminotransferase
Aspartate aminotransferase (AST) is an enzyme that is released by injured muscle cells and liver cell and is predominately found in the liver and heart. AST levels in the blood are most often used to monitor liver damage. AST is typically tested in conjunction with alanine aminotransferase (ALT) when a liver panel is ordered. High levels of AST in the bloodstream could indicate hepatitis, drug damage to the liver, cirrhosis, alcoholism, or other liver disorders. [Lab Tests Online:ast/tab/test] Source: Regenstrief LOINC
