Please see the NHANES 2017-March 2020 pre-pandemic data page for detailed information on this combined sample. Significance of the NIL result: The NIL indicates the presence of any residual interferon- found in the patients blood due to an infection with an organism requiring cell mediated immunity/T cell immunity (e.g. Tuberculosis - Quantiferon TB Gold Plus (0.5 international units/mL), and one secondary to a mitogen minus nil result that was less than 25% of the nil (another . We prospectively compared the results of QFTG to TST in HD patients. The positive control for each specime may be indeterminate due to processing errors or the patient & # ;.

Narrative Text Type Example, in the TB-antigen tube minus the value for the nil-control tube (TB-antigen minus nil value) was 0.35 IU/ml and when the TB minus nil value was 25% of the IFN-g concentration of the nil control. tuberculosis, M. bovis, M. africanum, M. microti, M. canetti) usually have Cleveland Clinic Laboratories. (n = 175/177) were due to low mitogen response (mitogen minus nil control, <0.5 IU/ml). The point where mitogens are no longer needed to move the cell cycle forward is called the "restriction point" and depends on cyclins to be passed. . Cell proliferation is often regulated by not only external mitogens but also by anti-mitogens, which inhibit cell cycle progression past G1. Aid in the detection of latent disease among persons at increased risk for tuberculosis (TB). M. tuberculosis infection likely. 80, pp. Indeterminate due to High Nil value: Indeterminate results due to a high level of IFN-gamma in the Nil (negative control) tube. Hug.
