Performance of QuantiFERON-TB Gold Plus for detection of latent tuberculosis infection in pregnant women living in a tuberculosis- and HIV-endemic setting. A dichotomous cut-off (0.35 IU/ml) defines a positive QFT without considering test variability. It is used to assure the patient has a healthy immune status and also serves as a control for correct blood handling and incubation. The association between borderline results and incident active TB within 3 to 24 months was investigated through linkage with the national TB-register. Depending on the strength of the immune response, a medical provider can determine if there is the possibility of an infection. The content you are about to view may be considered offensive and/or inappropriate. Mitogenesis is the induction (triggering) of mitosis, typically via a mitogen. 0.05 IU/mL. Half of the subjects in the borderline range will be negative at a level <0.20 IU/ml when retested and have a very low risk of developing incident active TB. They do so by binding to cell-surface receptors to initiate a complex array of intracellular signals that penetrate deep into the cytoplasm and nucleus (discussed in Chapter 15). The key difference between mitogen and growth factor is that mitogen is a small protein that induces the cell to begin cell division, while growth factor is a naturally occurring substance that is capable of stimulating cell proliferation, wound healing, and cellular differentiation. A mitogen is a small bioactive protein or peptide that induces a cell to begin cell division, or enhances the rate of division (). The analysis for the first and second measurements across the full range of nil, mitogen, and TB responses showed mean differences of 0.1 IU/ml, 0.2 IU/ml, and 0.1 IU/ml, respectively.

Blood collection tubes may be held at 4-27C for up to 3 days after incubation and prior to centrifugation. May also include abnormal ranges. The mitogen and nil tubes are identical between the two tests, and, as a reminder, the mitogen tube contains phytohemaglutanin, which serves as a positive control for T-cell activity, while the nil tube essentially measures the level of background or circulating IntraFERON-gamma in the patient.

It interferes with spindle formation and arrests cell division at metaphase. The CD8+ T cells normally participate in the host (patients) defense to MTB by producing interferon-gamma and other factors which activate macrophages to suppress growth of MTB in the patient, kill infected cells, or directly lyse intracellular MTB.
