What does Creatine Phosphokinase (CPK), Serum measure?
This test measures creatine phosphokinase (CPK), an enzyme found mainly in skeletal muscles, the heart, and the brain. CPK levels in blood may rise when muscle cells are injured or stressed. It may be used to help evaluate muscle damage, monitor certain muscle conditions, or assess possible heart-related muscle injury alongside other tests and clinical findings. Interpretation depends on symptoms, medical history, and other laboratory results.
