Which test is included in the special tests for pneumonia that helps identify HIV infection?

When evaluating pneumonia in a patient who may be immunocompromised, identifying HIV infection is important because HIV weakens the immune system and raises the risk of opportunistic pneumonias. The test that identifies HIV infection is the ELISA for HIV, which detects antibodies to the virus (and, in modern testing, may also screen for relevant antigens). A positive ELISA is typically followed by a confirmatory test. The other options either look for the causative organism in the lungs (sputum culture), provide imaging information (CT scan), or specifically test for tuberculosis (acid-fast stain), none of which determine HIV status.
