Which laboratory test is commonly ordered in cases of suspected appendicitis?

In cases of suspected appendicitis, a complete blood count (CBC) is commonly ordered because it helps to assess for signs of infection or inflammation. The CBC can reveal an elevated white blood cell count (leukocytosis), which is often indicative of an inflammatory process such as appendicitis. This test also provides additional information about the overall health of the patient by assessing red blood cells and platelets.

Other tests listed, such as urinalysis, may be performed to rule out urinary tract infections or other sources of abdominal pain, but they are not specifically diagnostic for appendicitis. Liver function tests are used to assess liver health and are not relevant in the context of suspected appendicitis. An electrolyte panel is used to check for imbalances in electrolytes, which may stem from various conditions but does not provide direct insight into appendicitis. Therefore, the CBC is essential for evaluating the likelihood of appendicitis and guiding further management.
