A mitogen is a peptide or small protein that induces a cell to begin cell division: mitosis. 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). eCollection 2022 Dec 22. inability of the patients lymphocytes to generate the interferon-gamma immune response because of. QuantiFERON is a powerful Premolecular diagnostic technology that delivers results with high sensitivity, enabling the detection of M. tuberculosis infection even in early or latent stages. Special collection, incubation, and centrifugation procedures must be followed. A dichotomous cut-off (0.35 IU/ml) defines a positive QFT without considering test variability. However, immune cells that respond to mitogens may not respond to other antigens. *For a test to be considered positive, the TB antigen tube value minus the Nil tube value must be 0.35 IU/mL (FDA cleared breakpoint). A low response to Mitogen (<0.5 IU/mL) indicates an Indeterminate result when a blood sample. Do not under or over-fill.
