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.
Creatine kinase (CK) is an enzyme found in the heart, brain, and skeletal muscle. High amounts of CK are released into the blood when there is muscle damage. A CK blood test may be used to detect inflammation of muscles (myositis) or muscle damage due to muscle disorders (myopathies).
