Creatine kinase, more commonly known as CK, is an enzyme that is present in all muscle tissue of the body including the heart and the brain. The normal creatine kinase levels in a man are between 38 and 174 units/L; while a woman's creatine kinase levels range from between 96 to 140 units/L.erum creatine levels indicate the overall health of the muscles within the body and if a serum creatine kinase test shows elevated levels, this is an indicator of strain on the muscles that may have been caused by simply heavy exercise or even something as serious as a heart attack.
