Creatine Kinase (CK), Total, Serum

FAQ

1. What is Creatine Kinase?

   Creatine Kinase (CK) is an enzyme that helps produce energy in the muscle. The greatest number of CK enzymes are found in striated muscles like skeletal muscles and the heart. Lesser amounts exist throughout the brain, gastrointestinal tract, and urinary bladder.

2. What is a Creatine Kinase test for?

   A Creatine Kinase test can be used as a marker for muscle injury. Conditions that can result in elevated Creatine Kinase are:

   • Heart attacks
   • Skeletal muscle injuries
   • Some muscle disorders

   These conditions can cause Creatine Kinase to be released into the bloodstream as a byproduct of muscle injury, increasing this enzyme's blood concentration.

3. Why test for Creatine Kinase?

   A CK test may be used to detect conditions related to muscle breakdown and inflammation, such as:

   • Myositis
   • Rhabdomyolysis
   • Myopathies
   • Heart attacks

   A series of CK tests may be used to monitor the progression or resolution of muscle damage. If your CK results are abnormal, your doctor will guide you through further testing and treatment options.
