Answer

In individuals who are immunosuppressed, are from third world countries, or have a history of travel, intestinal tuberculosis (TB) may need to be excluded. In such cases, tuberculin purified protein derivative (PPD) or interferon-gamma assays (eg, QuantiFERON-TB, T-SPOT, TB test) may be indicated, as well as culture for amebiasis, giardiasis, Strongyloides infection, and studies for histoplasmosis and coccidioidomycosis. [1] Chest radiography may exclude pulmonary TB, but this imaging modality does not exclude extrapulmonary TB. [1]
