Hi Vanessa. I ws sent to the urologist because of pain and blood in my urine. They did a series of tests including since antiobiotics didn't work, ct scan, ivp, rinalysis, cystoscopy at the urologist. Stones, cancer everything urological wise has been ruled out. The only test the urologist didn't do was the potassium test for ic, and he never even mentioned it to me. My gynecologist tested me for it, and I could definitely tell the difference between the two solutions.
