Both tubes contain peptide antigens from ESAT-6 and CFP-10 for stimulation of a CD4+ T-cell IFN-gamma response. In the 4 groups, 159 patients were positive by both TB1 and TB2 tubes, 1 patient was positive by TB1 only, and 4 were positive by TB2 only. A total of 1.1% (2/174) of results were indeterminate.

Taking it step by step, first evaluate the Nil and the mitogen result and then the results of the TB1 and TB2. Significance of the NIL result : The NIL indicates the presence of any residual interferon-γ found in the patient’s blood due to an infection with an organism requiring cell mediated immunity/T cell immunity (e.g. virus, fungus, intracellular bacteria, etc.). The MITOGEN-NIL value serves as the positive control for the patient specimen, demonstrating successful lymphocyte activity. The TB1-NIL tube specifically detects CD4+ lymphocyte reactivity, specifically stimulated by the TB1 antigens.
