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 nil tube value is subtracted from the values of the mitogen, TB1, and TB2 tubes for the final result of the respective tubes. When patient results are Indeterminate due to a low Mitogen result, a comment is attached to the result: Possible impaired cellular immune response.

For each patient, collect 1 mL of blood by venipuncture directly into each of the QFT - Plus Blood Collection Tubes. The agents which stimulate cell division are called mitogens, e.g., cytokinins, some steroids, however, some chemicals inhibit cell division, these are called mitotic poisons, e.g., azides, cyanides, colchicine, chalones, Page 2 etc. On test for Saturday-Sunday blood Draws: collect sample before 1500 and ship to next.
