About test
What does Creatine Phosphokinase Muscle/Brain (CPK MB), Serum measure?
This test measures the MB fraction of creatine phosphokinase (CPK-MB), an enzyme found mainly in heart muscle and, to a lesser extent, skeletal muscle. It may be used to help evaluate possible heart muscle injury or to monitor changes in cardiac enzyme levels alongside other clinical findings and tests. Results should be interpreted in the context of symptoms, medical history, and other investigations.
