Will Creatine Affect Blood Test Results?
There’s a compound in your body called creatinine. We measure it in the blood as part of most routine blood work. The value obtained can be correlated to how well your kidneys are functioning. Creatinine is an inactive derivative of creatine. Supplementing with creatine can affect creatinine levels in the blood. This is very minor and if you tell your doctor you are using creatine, the tests will still be easy to interpret for him or herself.
