In evaluating suspected interstitial cystitis, which tests are mandatory?

• A. Urinalysis and urine culture
• B. Complete blood count
• C. Renal ultrasound
• D. Chest X-ray

Answer: (A)

The essential step when evaluating suspected interstitial cystitis is to exclude infectious causes, since infection can mimic IC symptoms. A urinalysis is needed to detect signs of infection, blood, or inflammation in the urine, while a urine culture confirms whether bacteria are present and identifies the pathogen. If infection is found, the symptoms are more likely due to a urinary tract infection rather than interstitial cystitis, so treatment would target the infection rather than pursuing IC-specific management. Because of this priority, urinalysis and urine culture are the routine, mandatory tests in the initial evaluation. The other tests aren’t routinely required for diagnosing suspected IC. A complete blood count isn’t necessary unless there are systemic signs or several red flags suggesting another process. Renal ultrasound would be reserved for symptoms or exam findings suggesting stones, obstruction, or other renal pathology. A chest X-ray has no role in evaluating bladder symptoms unless there are specific respiratory concerns.
