Posted December 17, 20186 yr comment_75412 Hi All, Does anyone out there have a critical value for CPK (Creatine Phosphokinase)????? If so, what is your cut off value? We do not currently have a critical value for this test, but our medical director was asked by a specialist to consider a cut off of 2000mg/dL where he considers that a very high abnormal for patients he typically sees. However, we do orthopedic surgery here and do not think this is a good place to start, if we add this at all. Any thoughts would be very appreciated!!!!! Linda
