Depends on units,lab: In the US, the CK (Creatine phosphoKinase) or CPK levels are often reported with UNITS (which you didn't list) of mcg/L. Older labs use "U/L" (Units per Liter) based on their internal standard. Usually, the lab's reference range ("normal") is listed next to the number on the lab report. Without seeing a copy of the report, it is hard to comment on whether it is "normal" or not. Use HealthTap Prime
