Which initial laboratory tests are commonly ordered for evaluating abdominal pain?

The initial laboratory tests commonly ordered for evaluating abdominal pain include a complete blood count (CBC) and a basic metabolic panel (BMP).

A CBC is useful in assessing for signs of infection, anemia, or other hematological conditions that might indicate an underlying issue related to abdominal pain. It provides information on red and white blood cell counts, hemoglobin levels, and platelet counts, which can be crucial in diagnosing conditions such as appendicitis, diverticulitis, or other inflammatory processes.

The BMP complements the CBC by evaluating the chemical balance and metabolism in the body, including glucose levels, electrolyte levels (such as sodium, potassium, and chloride), and kidney function indicators (like blood urea nitrogen and creatinine). Abnormalities in these values can reveal problems related to dehydration, renal impairment, or metabolic issues that may present with abdominal pain.

Together, these tests provide a comprehensive overview of the patient's general health and can guide further diagnostic and therapeutic interventions.
