CK-MB (Creatine kinase MB)
Rapid CDIATM CK-MB kits are intended for the diagnosis of heart attacks, including myocardial infarction.
Creatine kinase is a dimer existing in three isoenzymic forms, depending on the particular combination of its subunits: BB(brain type);MM(skeletal type); and MB(hybrid type). Creatine kinase-MB isoenzyme is released into circulation later than myoglubin, reaching abnormal levels within 4 to 6 hours after onset of symptoms. It reaches its highest level after about 18 to 24 hours, and returns to normal in about 2 to 3 days. CK-MB is widely recognized as the traditional marker for the diagnosis of acute myocardial infarction (AMI).
