Testing for Interstitial Cystitis (IC)
There is no specific test to diagnose interstitial cystitis. Also, because its symptoms overlap with those of several other conditions, your doctor will first need to rule out other possible causes.
Tests your doctor may order or perform include:
- Urinalysis: This test helps your doctor rule out an infection.
- Cystoscopy: In this procedure, a doctor inserts a long, narrow tube with a camera, called a cystoscope, into the urethra and up to the bladder. This allows the doctor to view the inside of the bladder for ulcers, bleeding, or signs of cancer.
- Bladder Distention or Instillation: As part of a cystoscopy procedure, the doctor may slowly fill your bladder with liquid to test how much urine it can hold.
- Biopsy: During a cystoscopy procedure, your doctor may also remove a sample of tissue from your bladder to test for cancer.
