Tests and diagnosisBy Mayo Clinic Staff
If you have symptoms of cystitis, talk to your doctor as soon as possible. In addition to discussing your signs and symptoms and your medical history, your doctor may recommend certain tests, such as:
March 18, 2015
- Urine analysis. For a suspected bladder infection, your doctor may ask for a urine sample to determine whether bacteria, blood or pus is in your urine. If so, he or she may request a urine bacterial culture.
Cystoscopy. During this test, your doctor inserts a cystoscope — a thin tube with a light and camera attached — through the urethra into your bladder to view your urinary tract for signs of disease.
Using the cystoscope, your doctor can also remove a small sample of tissue (biopsy) for lab analysis. But this test most likely won't be needed if this is the first time you've had signs or symptoms of cystitis.
- Imaging. An imaging test usually isn't needed, but in some instances — especially when no evidence of infection is found — imaging may be helpful. For example, an X-ray or ultrasound may help your doctor discover other potential causes of bladder inflammation, such as a tumor or structural abnormality.
