Clinical Significance

A CK test may be ordered whenever muscle damage is suspected and at regular intervals to monitor for continued damage. It may be ordered when someone has experienced physical trauma, such as crushing injuries or extensive burns. The test may be ordered when a person has symptoms associated with muscle injury such as muscle pain or weakness and when a person has nonspecific symptoms, especially when taking a drug or after an exposure to a substance that has been linked with potential muscle damage.



The CK test may sometimes be ordered when a person has chest pain and a heart attack is suspected. It may be ordered after a heart attack has been diagnosed to monitor for ongoing heart damage.
