Computerized tomography (CT) scan. In patients who are not pregnant, a CT scan (a type of X-ray study) of the area of the appendix is useful in diagnosing appendicitis and peri-appendiceal abscesses as well as in excluding other diseases inside the abdomen and pelvis that can mimic appendicitis.
Laboratory tests are not specific for appendicitis, but they may be helpful to confirm diagnosis in patients with an atypical presentation.For example, liver and pancreatic function tests (eg, transaminases, bilirubin, alkaline phosphatase, serum lipase, amylase) may be helpful to determine the diagnosis in patients with an unclear presentation.
