Future Diagnostic Tools for Interstitial Cystitis

As researchers learn more about the causes of IC, more accurate and less invasive diagnostic procedures are likely to emerge. For example, some researchers are studying the possibility that urine samples from people with IC contain substances not found in normal urine. If an IC marker in the urine can be found, patients may not have to undergo a cystoscopic examination or biopsy to receive a diagnosis.
