Mitogenesis is the induction (triggering) of mitosis, typically via a mitogen. Additional information related to the test. TST and QFT do not measure the same components of the immunologic response and are not interchangeable. Mitogen - Nil: High, usually >10.0: This is a measure of the cell's ability to produce gamma interferon in response to non-specific mitogen stimulation.

The mitogen tube also acts as a false negative control. A qualitative result (i.e., Negative, Positive, or Indeterminate) is based on interpretation of the four values, Nil, TB1 minus Nil, TB2 minus Nil, and Mitogen minus Nil. Mitogen-Nil The maximum non-specific stimulated interferon- gamma level that may be produced by the patients lymphocytes minus the Nil (i.e., basal) level of interferon-gamma. RR-6):1--51. A qualitative result (Negative, Positive, or Indeterminate) is based on interpretation of the four values, NIL, MITOGEN minus NIL (MITOGEN-NIL), TB1 minus NIL (TB1-NIL), and TB2 minus NIL (TB2-NIL). Lithium-Heparin tube must not remain at room temperature for more than 3 hours after collection. Elevated Nil values greater than 8.0 IU/mL will produce a test interpretation of Indeterminate. False positive results may occur in patients with prior infection withM. marinum, M. szulgai,andM. kansasii. How do the indirect TB tests work?DuringM. tuberculosisinfection, the body generates cell-mediated immune (CMI) responses to the TB organismand its antigens.
