What is creatine phosphokinase (CK)?

Creatine phosphokinase (a.k.a., creatine kinase, CPK, or CK) is an enzyme (a protein that helps to elicit chemical changes in your body) found in your heart, brain, and skeletal muscles. When muscle tissue is damaged, CPK leaks into your blood.

What is a CPK enzyme & how does it work?

As its name suggests, the function of the CPK enzyme is to add a phosphate group to creatine, a naturally occurring chemical found in your muscle cells. As a result, creatine turns into phosphocreatine — a high-energy substance used by your body to generate energy.

What does CPK stand for?

StatPearls [Internet]. Ravinder S. Aujla; Roshan Patel. Last Update: October 24, 2022. Creatine phosphokinase (CPK), also known by the name creatine kinase (CK), is the enzyme that catalyzes the reaction of creatine and adenosine triphosphate (ATP) to phosphocreatine (PCr) and adenosine diphosphate (ADP).

What does high CPK mean on a blood test?

If the test finds high total CPK levels in your blood, this could mean that either acute (short-term) or chronic (long-term) degeneration or damage has happened to your heart, brain, or skeletal muscle. Keep in mind that in case of certain injuries, the CPK enzyme levels peak only after two days have passed.
