Not significant: A low serum creatinine is probably not clinically significant and may depend on the lab method being used and your protein intake from meat. Serum creatinine measures the efficiency of your kidneys in removing metabolic waste.

?low protein diet: are you on a low protein diet--that could do it.

Not much-: An important thing to remember is that lab results are not useful unless there is a clinical context. Advice is based on focusing on the patient, not the numbers. Though you mention the BUN and Creatinine as being "very low",where there symptoms when labs were drawn? Why were they drawn in the first place? Without this context, it is best to ask your doctor what the results mean.

Don't Rx a lab value: My first concern is whether one of your arthritis meds is causing a mild interstitial nephritis. Your physician is the one who can answer this. You may be in for a trial of a medication change and/or a check of your ability to concentrate urine -- or this very slightly elevated creatinine may just be the result of getting a little older and perhaps having had some past damage.

Kidney insufficiency: On the surface, these blood test results suggest a significant degree of impairment of the function of your kidneys. This needs to be our first presumption, unfortunately. You need to follow up with your doctor for blood testing, urine testing and ultrasound to start.
