Frequent, weak, stop and go urination, itchy skin. what are the chances i have a kidney disease?

Need test: The main tests for kidney function are serum creatinine and eGFR and presence of protein, especially albumin in urine. If you have any concern see your doctor. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
