There are several factors that can cause protein in urine - not all are diabetes related or kidney failure starting. Contamination of sample by other body secretions, high protein diet, recent high intensity exercise are a few but can also be associated with high BG levels and glucose in urine. I had fairly significant protein in urine when first diagnosed, but this did quickly resolve once my BG levels were better controlled. I would wait to see result of second test before worrying to much. IF it is still elevated ask doctor to run eGFR (kidney function) test - this needs a blood test.
