The only rapid test for active tuberculosis is smear microscopy, which has poor sensitivity for both extrapulmonary and less extensive pulmonary forms of tuberculosis (1). Nucleic acid amplification tests have somewhat better but still suboptimal sensitivity (2), whereas mycobacterial cultures are sensitive but require several weeks before results are available (1). The tuberculin skin test (TST) and the new interferon-γ release assays (3, 4) detect a cellular immune response to tuberculosis antigens. On the basis of numerous longitudinal studies (5), the TST is considered to have good sensitivity for the detection of latent ...References1. Brodie D, Schluger NW. The diagnosis of tuberculosis.
