The tuberculin skin test [TST] is implanted just under the skin and then sits for a predetermined amount of time. The underlying paradigm for indirect testing is that patients with TB-sensitized lymphocytes will produce a stronger CMI response than cells that have never been exposed to the antigen.

T cells are one of two primary types of lymphocytesB cells being the second typethat determine the specificity of immune response to antigens (foreign substances) in the body. The phlebotomists at the collection centre of Super Religare Laboratories and its clients draw blood from voluntary test seekers for QFT-G assay and place it directly into three 1 mL tubes each containing either ESAT-6, CFP-10 and TB7.7 or PHA (a mitogen used as a control with a positive assay result) or saline (used as a nil sample to measure the background level of IFN-). B-cell mitogens stimulate human peripheral blood lymphocytes in the following order of effectiveness: levan, lipopolysaccharide, dextran. 0000009517 00000 n The Nil sample adjusts for background, heterophile antibody effects, or non-specific IFN- in blood samples. TST and QFT do not measure the same components of the immunologic response and are not interchangeable. However, in patients with high suspicion of exposure, a negative test should be repeated on a new sample. TST, interpretation and indicated applications of QFT differ between those persons at low risk and those at increased risk for Must be collected and shipped directly to ARUP the same calendar day. The way we interpret it is, there should be a difference of more than O.35 IU/ml, between TB antigen ( 0.479 in your case ) and nil antigen (0.040 ). The in vitro responses to these mitogens were abolished by the removal of B lymphocytes or by the depletion of phagocytic cells. Pottumarthy S, Morris AJ, Harrison AC, Wells VC. 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.

During G2 phase, the cell is again stable. A growth factor is a naturally occurring substance capable of stimulating cell proliferation, wound healing, and occasionally cellular differentiation. 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.
