CK-MB (CK-2) 0017581

The Creatinine Kinase-Myoglobin Biomarker (CK-MB) is a more specific test for the heart muscle than the CK alone. It is used distinguish between skeletal muscle and heart muscle damage when your doctor suspects that you’ve had a heart attack (that is, if the troponin test is not available) especially in the presence of an elevated CK (Creatinine Kinase) and the reason is not obvious.
