UTIs can be diagnosed by analyzing a urine sample. The urine is examined under a microscope for bacteria or white blood cells, which are signs of infection. Your health care provider may also take a urine culture. To schedule an appointment for a urological concern, please call METROWEST UROLOGY at (508) 655-4422.
