No IFN-gamma response to M tuberculosis antigens was detected. Most indeter-minate tests (n 175/177) were due to low mitogen response (mitogen minus nil control,,0.5 IU/ml). Special collection, incubation, and centrifugation procedures must be followed. A single positive result by this test should not be used solely to diagnose latent tuberculosis (TB). system uses specialized blood collection tubes, which are used to collect whole The TB2 minus Nil value indicates interferon-gamma response of both CD4+ and CD8+ T lymphocytes, stimulated by the TB2 antigens.
