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.
What is CK? CK is an abbreviation for creatine kinase - also known as CPK - or phosphocreatine kinase. Creatine kinase is a muscle enzyme found in three different types in the human body. In skeletal muscle itâs in the form of CK-MM, in the brain, CK-BB, and in the heart muscle, CK-MB.
