Frequencies of mycobacterium tuberculosis specific IFN-γsecreting T cells in peripheral blood. In patients with female genital tuberculosis, the frequencies of spots forming cells (SFCs) responding to early-secreted antigenic target 6-kDa protein and culture filtrate protein 10, respectively, and in total were all significantly different from those observed in non-TB patients (P < 0.01). The dividing line indicating the cutoff value of a positive T-SPOT.TB test (24 SFCs/10⁶ PBMCs). PBMCs = peripheral blood mononuclear cells, SFCs = spots forming cells.
