Tests for painful bladder syndrome may initially include an analysis of the urine and blood stream to identify any infection. A pelvic exam might also be conducted to examine your pelvic organs (vagina, cervix, etc.) along with rectum and anus.
Some doctors rely on the potassium sensitivity test for an indication of the painful bladder syndrome. This test compares your urgency to urinate with two different solutions (water and potassium chloride) in your bladder.
For a visual examination, your doctor might decide to examine the inner lining of the bladder by inserting a long, thin, camera-fitted tube via path of the urethra. This process is called cystoscopy.
Finally, for a decisive diagnosis, biopsy of the bladder might be performed. This process involves removing tissues from the bladder for lab analysis.
