Muscle Breakdown Test (CK, TOTAL)

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

When the total CPK level is very high, it usually means there has been injury or stress to the heart, the brain, or muscle tissue. For example, when a muscle is damaged, CPK leaks into the bloodstream. Determining which specific form of CPK is high helps doctors determine which tissue has been damaged.

The pattern and timing of a rise or fall in CPK levels can be diagnostically significant, particularly if a heart attack is suspected.

Special Preparation: None.
