Additional Information

Testing begins with total creatine kinase analysis (CK). If the total CK activity is <100 U/L testing is complete. CK isoenzyme electrophoresis testing will not be performed. If the total CK activity is > or =100 U/L, CK isoenzyme electrophoresis (CKEL) will be performed at an additional charge.. Test sent to Mayo Medical Laboratories.
