Yes.
However, creatinine is what they use to measure your renal function. However, for people that supplement creatine, the creatinine test is useless as people that supplement creatine will have higher levels.
If you are getting your yearly physical done, tell your doctor you take creatine.
1. Your doctor says creatine is dangerous
a. Your doctor hasn't read up on his facts
b. Find a new doctor
2. Your doctor should be able to have an alternative test done for renal health
You can avoid all this shit by drinking a proper amount of water (read 3l/1gal).
