Thus from a licensing standpoint, the annual NIL value per student-athlete could range from $1,000 - $10,000, whereas professional athletes garner between $50,000 - $400,000 for the same group usage licenses. This is a measure of the cells ability to produce gamma interferon in response to non-specific mitogen stimulation. In a CDC-sponsored multicenter trial, QFT and TST results were moderately A mitogen is a small bioactive protein or peptide that induces a cell to begin cell division, or enhances the rate of division ( mitosis ).

Mitogen-Nil The maximum non-specific stimulated interferon- gamma level that may be produced by the patient's lymphocytes minus the Nil (i.e., basal) level of interferon-gamma. I presume your 2 year old child had received the BCG vaccination. the concentration of IFN- in the separated plasma is determined by enzyme-linked immunosorbent assay (ELISA). Improper specimen collection and handling are the most common reasons for an indeterminate result. Components of the organ or disease panels may be ordered individually. It's used to look at overall health and find a wide range of conditions, including anemia, infection and leukemia. The magnitude of the measured gamma interferon level cannot be correlated to stage or degree of infection, level of immune responsiveness, or likelihood for progression to active disease. (6). A cell cycle is a series of events that takes place in a cell as it grows and divides. of active, infectious tuberculosis might result in extensive transmission to highly susceptible populations. Quantiferon TB test interpretation is slightly difficult. View All.

The QuantiFERON-TB Gold blood test takes some of the guesswork out of the tuberculosis screening process. Fortunately, the ESAT-6 and CFP-10 antigens are absent from all BCG strains and from most non-tuberculosis mycobacteria. 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-). Low values can occur due to sample handling errors that adversely impact lymphocyte activity/viability, low lymphocyte counts, and other factors that decrease cell mediated immune responses. 0000007480 00000 n If technical issues are suspected with the collection or handling of blood samples, repeat the entire QuantiFERON TB Gold Plus test with new blood specimens.

This statement provides interim recommendations for using and interpreting QFT. Gerald H. Mazurek, M.D. QFT results are based on the proportion of IFN- released in response to tuberculin as compared with mitogen, QFT uses unique blood collection tubes that enable immediate exposure of viable blood lymphocytes to highly specific TB antigens (ESAT-6/CFP-10/TB-7.7 (p4)).
