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 order these tests:
- Urine analysis. If it's suspected that you have a bladder infection, your doctor may ask for a urine sample to determine whether bacteria, blood or pus is in your urine.
- Cystoscopy. Inspection of your bladder with a cystoscope — a thin tube with a light and camera attached that can be inserted through the urethra into your bladder — may help with the diagnosis. Your doctor can also use the cystoscope to remove a small sample of tissue (biopsy) for analysis in the lab. This test most likely won't be needed if this is the first time you've had signs or symptoms of cystitis.
- Imaging tests. Imaging tests usually aren't necessary, but in some instances — especially when no evidence of infection is found — they may be helpful. For example, an X-ray or ultrasound may help rule out other potential causes of bladder inflammation, such as a tumor or structural abnormality.
