Creatine Kinase (CK) Test. This blood test measures an enzyme called creatine kinase (CK) or creatine phosphokinase (CPK). Enzymes are chemicals that help the cells of your body work. Muscle cells make the creatine kinase enzyme. When muscle cells are injured or diseased, enzymes leak out of the cells and enter the bloodstream.
Test: CPK, Creatine Phosphokinase (CK) Creatine Kinase. This is a blood chemistry test to measure the amount of enzyme in the blood. The CPK enzyme is found in high concentration in heart and skeletal muscle; low concentration is brain tissue. CPK is an enzyme that catalyzes the creatine-creatinine metabolic pathway in muscle cells and brain tissue.
