Creatine Kinase MB (CK-MB) is an enzyme present in the cardiac muscle with a molecular weight of 87.0 kDa.Creatine Kinase is a dimeric molecule formed from two subunits designated as “M” and “B” which combine to form three different isoenzymes, CK-MM, CK-BB, and CK-MB. CK-MB is the isoenzyme of Creatine Kinase most involved in the metabolism of cardiac muscle tissue
Creatine Kinase MB (CK-MB) is an enzyme present in the cardiac muscle with a molecular weight of 87.0 kDa.1Creatine Kinase is a dimeric molecule formed from two subunits designated as “M” and “B” which combine to form three different isoenzymes, CK-MM, CKBB, and CK-MB. CK-MB is the isoenzyme of Creatine Kinase most involved in the metabolism of cardiac muscle tissue. 2 The release of CK-MB into the blood following MI can be detected within 3-8 hours after the onset of symptoms. It peaks within 9 to 30 hours, and returns to baseline levels within 48 to 72 hours. 3 CK-MB is one of the most important cardiac markers and is widely recognized as the traditional marker for the diagnosis of MI. The CK-MB Rapid Test Cassette (Whole Blood/Serum/Plasma) is a simple test that utilizes a combination of antibody coated particles and capture reagents to qualitatively detect CK-MB in whole blood, serum or plasma. The minimum detection level is 5 ng/mL CK-MB
