From last few months while urinating I see foamy urine, I did routine urine test it showed single + protein detected in urine, then I did blood serum Urea and Creatinine test results were normal, blood Urea nitrogen 15 mg/dL and Creatinine 1.18 mg/dL , then I did protien/ Creatinine ratio test which came high 0.98 mg/mg Creatinine I did blood sugar fasting test it came 110 mg/dL So please advise me what to do now and what is the reason of protein leak in my urine and how to cure it.
