blood enzyme activity assay blood creatine kinase activity assay 2022-02-24T16:36:18Z MMO:0000799 This is a method which quantifies the enzymatic activity of creatine kinase (CK) in a specified sample of blood. CK catalyses the reversible transfer of phosphate between ATP and various phosphogens such as creatine phosphate. Blood CK level is used as an enzymatic marker for myocardial infarction, rhabdomyolysis and acute renal failure. blood CK activity assay blood CPK activity assay blood creatine phosphokinase activity assay blood phosphocreatine kinase activity assay measurement_method_ontology slaulede
