The TB2 minus Nil value indicates interferon-gamma response of both CD4+ and CD8+ T lymphocytes, stimulated by the TB2 antigens. Among tuberculosis patients, a weak mitogen response was associated with a false-negative QFT result (75%) compared to a normal response (20%). During M. tuberculosis infection, the body generates cell-mediated immune (CMI) responses to the TB organism and its antigens. The agents which stimulate cell division are called mitogens, e.g., cytokinins, some steroids, however, some chemicals inhibit cell division, these are called mitotic poisons, e.g., azides, cyanides, colchicine, chalones, Page 2 etc. Mitogen tube. 29 the InBios active TbDetectanti-TB IgG antibody assay positive, the QuantiFERON - Gold!
