Mitogen stimulation leads to immune cell activation and is used as a measure of general immune function. A mitogen is a peptide or small protein that induces a cell to begin cell division: mitosis. The TB2 minus Nil value indicates interferon-gamma response of both CD4+ and CD8+ T lymphocytes, stimulated by the TB2 antigens. those with TB response less than 0.25 IU/ml and nil control greater than or equal to 0.1 IU/ml, and those with TB response 0.25-0.35 IU/ml, regardless of nil control value. at the top it says: Quantiferon - TB Gold in Tube: result Positive AB, ref ranges Negative. The association between borderline results and incident active TB within 3 to 24 months was investigated through linkage with the national TB-register. M. tuberculosis complex infection unlikely. 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.

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. See Special information section. eCollection 2018. A diagnosis of LTBI requires that TB disease be excluded by medical evaluation, which should include checking for signs and symptoms suggestive of TB disease, a chest radiograph, and, when indicated, examination of sputum or other clinical samples for the Reproducibility of interferon gamma (IFN-) release Assays. Performance of QuantiFERON-TB Gold Plus for detection of latent tuberculosis infection in pregnant women living in a tuberculosis- and HIV-endemic setting. 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. QuantiFERON-TB 4 -TB (QuantiFERON-TB Gold Plus = QFT-Plus) QuantiFERON-TB Gold (QFT) 60 2017 1 60 . A borderline range (0.20-0.99 IU/ml) was introduced in 2010 recommending a follow-up sample.

The mitogen tube must demonstrate an interferon- value of equal to or greater than 0.5 IU/ml higher than the value of the NIL tube. Lectins recognize particular carbohydrate moieties on membrane glycoproteins on the surfaces of host cells. Many mitogens are lectins, carbohydrate-binding proteins usually derived from bacteria or plants. TB1-Nil >0.35 is The tubes are shaken to mix antigen with the whole blood and incubated at 37 C + 1 C for 16 to 24 hours.
