The Acute Care™ CK-MB assay is an in vitro diagnostic test for the measurement of the MB iso-enzyme of creatine kinase in heparinized whole blood/plasma. CK-MB measurements can be used as an aid in diagnosing acute myocardial infarction.
CK-MB is found primarily in cardiac tissue.1 CK-MB can be detected at elevated concentrations following myocardial damage. Abnormal plasma CK-MB concentrations are often associated with ischemia or necrotic heart injury. The increase in CK-MB concentration is often evident within 3 to 6 hours following onset of chest pain, reaching peak concentrations within 12 to 24 hours. CK-MB concentrations will generally return to normal within 24 to 72 hours.2 The determination of CK-MB is most beneficial when samples have been drawn at appropriate time intervals post onset of chest pain.
