I have had a creatinine level of 0.8 for the last year or so. Every time I go to the rest room sometimes my urine is completely clear when I have not drank any water at all, other times is a very light pale yellow. I am not sure what to do. When I had urine dip stick test run back in December of 2018 it showed no protein, bilirubin or ketones or glucose in my urine. My GRF at the local emergency room for that same visit was 87. Using the calculator online it says it should be 96. Sometimes also my creatinine dips to 0.7 then back up to 0.8. I am at a loss of words as to what to do. My doctor will not send me to a nephrologist because he does not think there is any problem. All of 2007 my creatinine was 0.7 then in 2018 went up 0.8 then comes back down to 0.7. Would you be able to think of any possible problems that could be causing the clear urine without drinking lots of water?

The normal variation in the serum creatinine from day to day in laboratory testing is plus or minus 0.2 milligrams per deciliter (mg/dl). Hence, the numbers that you quote are not significantly different from each other and are in the normal range. The color of your urine has more to do with foods that you eat. The water you drink may lighten the urine but this is not a very good indicator of disease. I do not find evidence of kidney disease based on the information that you present.
