Dear Joseph,
Creatinine is produced in proportion to the total muscle mass. If you are a very large or muscular individual, you might have a slightly elevated creatinine. You could also be an exercise fanatic, the constant formation of creatinine may at times exceed the ability of your kidneys to eliminate this by-product of creatine. I don’t think that one spot value in time is a reason to think you have kidney failure or a renal stone, but rather a value that should be repeated to establish a trend or a baseline value.
I personally would not go changing my diet or start drinking enormous quantities of water until a problem has been established. Normal lab values are meant to categorize the majority of people in to safe ranges. If you are slightly out of this range , which you are, this simply means that further evaluation or consideration of why this value is elevated needs to be performed. If your doctor says this is nothing to be concerned about, I would believe him. If you are still concerned or have symptoms that concern you, I would repeat the test before altering your lifestyle. Continue to consult your physician, if there is something a Urologist needs to handle, a referral would be in order. Good Luck!
