If your symptoms are not typical, further tests may be needed to confirm the diagnosis and rule out other conditions.
You may have:
- a blood test to look for signs of infection
- a pregnancy test for women
- a urine test to rule out other conditions, such as a bladder infection
- an ultrasound scan to see if the appendix is swollen
- a CT scan
It can sometimes take a while to get the test results.
Your surgeon may recommend a laparoscopy to examine your appendix and pelvic organs if the diagnosis is still uncertain.
Removing the appendix is usually recommended if appendicitis is suspected, rather than risk it bursting.
This means some people will have their appendix removed even though it's eventually found to be normal.
If a doctor is unsure whether you have appendicitis, they may recommend waiting up to 24 hours to see if your symptoms improve, stay the same or get worse.
If they suspect your appendix has burst, you'll be sent to hospital immediately for treatment.
