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 blood test is a laboratory test that measures creatine phosphokinase (CPK), which is one of the enzymes found in the brain, heart, and skeletal muscles. This is a useful test for helping doctors to diagnose problems such as muscle damage, heart attack, and related conditions.slide 1 of 4.urpose. When the CPK level in the blood is very high, it often means there has been injury or stress to the heart, skeletal muscle tissue, or even the brain. This is because CPK leaks into the bloodstream whenever this type of damage occurs.
