Appendicitis is suspected by the symptoms presented by the child and a good scan on the abdomen. If you think there is an inflammation of the appendix, can be useful to complete the study with some evidence: blood, urine, X-ray and / or ultrasound of the abdomen, etc.. Unfortunately there are none that would ensure the diagnosis in all cases. The “test” more targeted and ultimately will determine the referral to the surgeon is abdominal palpation.
