abnormal circulating aspartate transaminase level decreased circulating aspartate transaminase level MP:0005632 MPheno.ontology decreased AST level decreased circulating AAT level decreased circulating ASAT level decreased circulating SGOT level decreased circulating aspartate aminotransferase level decreased circulating serum glutamic oxaloacetic transaminase level less than normal concentration in the blood of this enzyme, which catalyzes the reversible transfer of an amine group from l-glutamic acid to oxaloacetic acid, forming alpha-ketoglutaric acid and l-aspartic acid; aids in diagnosis of viral hepatitis and myocardial infarction reduced AST level reduced circulating AAT level reduced circulating ASAT level reduced circulating SGOT level reduced circulating aspartate aminotransferase level reduced circulating aspartate transaminase level reduced circulating serum glutamic oxaloacetic transaminase level
