Most centrioles form by duplication, where each of the two-preexisting centrioles direct the formation of one new procentriole, providing a mechanism to control the number of centrioles formed. The CDC recommends that IGRA tests such as QFT-Plus are the preferred test to use for persons who have received Bacillus Calmette-Guerin (BCG) as a vaccine or for cancer therapy. This test is for the diagnosis of latent TB (tuberculosis) infection, but not of active TB disease which requires AFB culture and smear (See AFBHSC). Peripheral blood mononuclear cells (PBMC) are cultured in vitro with plant lectins (mitogens) such as phytohemagglutinin (PHA) and pokeweed mitogen (PWM). The black mark on the side of the tubes indicates the validated range of 0.8 - 1.2 mL. Pokeweed Mitogen (PWM)-induced Lymphocyte Proliferation Measurement of human lymphocytes proliferative responses to various stimuli is a fundamental technique used to assess their biological status and functions. Federal government websites often end in .gov or .mil. Table 2. Indeterminate result suggests the need for further investigation or repeat testing.

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. For each patient, collect 1 mL of blood by venipuncture directly into each of the QFT - Plus Blood Collection Tubes. The QuantiFERON-TB Gold Plus result is determined by subtracting the Nil value from either TB antigen (Ag) tube.
