When cells are damaged by disease or injury, large amounts of these leak out, causing blood tests to show that enzymes are elevated above normal. (You can roughly compare this situation to a car that's leaking oil. Leaks in many parts of the engine can have the same result: oil all over your driveway.)
An enzyme called creatine phosphokinase (CPK) is important for muscle function. The CPK isoenzymes test is a way to measure the levels of this enzyme in your bloodstream. CPK can be broken down into three separate parts: CPK-1 is mainly found in your brain and lungs.
