CREATININE PHOSPHOKINASE (MUSCLE/BRAIN)

The creatinine phosphokinase (CPK) muscle/brain test specifically measures the levels of CPK isoenzymes, CPK-MB (heart) and CPK-MM (skeletal muscle), in the blood. Elevated CPK-MB levels can indicate myocardial infarction (heart attack), while elevated CPK-MM levels suggest muscle damage or disease. This test is used to diagnose and monitor heart and muscle conditions, such as myocardial infarction, rhabdomyolysis, and muscular dystrophy. It provides valuable information for assessing the severity of muscle and heart damage, guiding treatment decisions, and monitoring the effectiveness of therapeutic interventions.
