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.
The CPK isoenzymes test measures the different forms of creatine phosphokinase (CPK) in the blood. CPK is an enzyme found mainly in the heart, brain, and skeletal muscle. A blood sample is needed. This may be taken from a vein. The test is called a venipuncture. If you are in the hospital, this test may be repeated over 2 or 3 days. A significant rise or fall in the total CPK or CPK isoenzymes can help your health care provider diagnosis certain conditions.
