Tube 1: Contains only the patient's blood with nothing added (NIL) ("Negative control") Tube 2: Contains non-specific mitogens that stimulate patient's T-cells ("Positive control") Tube 3: Contains specific TB antigens; Since QFT-IT is an IFN- release assay, IFN- is measured in each tube after 16-24 h incubation.

The mononuclear cells (MNC) of cancer patients depressed the mitogen responses of normal cells in a coculture system. Progression through the cell cycle is controlled by cyclin-dependent protein kinases (Cdks), but the mechanisms that link growth factor signaling to the cell cycle machinery have not been established. I got a chest x-ray afterwards, which came out fine, and I had no symptoms, so I retook the test at a different lab, and my results were negative: TB1-Nil of 0.07, TB2-Nil of 0.09, Nil value of 0.01, and Mitogen value of >10.

A low response to Mitogen (<0.5 IU/mL) indicates an Indeterminate result when a blood sample. Lymphokines act to attract additional immune cells to mount an immune response, for instance in stimulating B cells to generate antibodies against the invading pathogen. Compared with TST, QFT results
The TB1-NIL tube specifically detects CD4+ lymphocyte reactivity, specifically stimulated by the TB1 antigens.
In absence of that, please do not worry. High Nil values are often seen in various autoimmune diseases and conditions. Repeat testing does not boost subsequent immune responses. Division of Tuberculosis Elimination
