The enzyme aspartate aminotransferase (AST) is widely distributed in tissues, principally: hepatic, cardiac, muscle, and kidney. Elevated serum levels are found in diseases involving these tissues
Haemolysed samples are not assayed. Cyanokit (Hydroxocobalamin) may cause interference with results. Sulfasalazine and sulfapyradine at therapeutic concentrations may cause falsely low or high results.
