The creatinine results that you describe are within the range of variation for the laboratory testing. The creatinine tests can vary between 0.1 and 0.15 up and down and this is just the normal variation in the accuracy of the testing. Hence, these numbers are basically the same and might suggest that you have an early stage of chronic kidney disease (CKD). I suspect that you are in Stage 3a CKD. The results of your urine tests are reassuring in that you do not have blood, protein or infection that is complicating your CKD. I would still recommend followup of your kidney function tests every 6 to 12 months.
