Creatine phosphokinase (CPK)

Optimal range: 29 - 168 U/L

Creatine phosphokinase (CPK) is an enzyme in the body. It is found mainly in the heart, brain, and skeletal muscle.

This test may be used to:

  • Diagnose heart attack
  • Evaluate cause of chest pain
  • Determine if or how badly a muscle is damaged
  • Detect dermatomyositis, polymyositis, and other muscle diseases
  • Tell the difference between malignant hyperthermia and postoperative infection



Optimal range: 0 - 0.06 ng/mL

Troponin proteins are released when the heart muscle has been damaged, such as occurs with a heart attack. The more damage there is to the heart, the greater the amount of troponin T and I there will be in the blood.
