The TB1 minus Nil value indicates the interferon-gamma response of CD4+ T lymphocytes, specifically stimulated by the TB1 antigens. Indeterminate results are uncommon and may be caused by a number of factors. testing of persons for whom LTBI screening is performed but who are not considered to have an increased probability if plans are also in place for the necessary follow-up medical evaluation and treatment (e.g., chest radiograph or LTBI Active tuberculosis is associated with suppressed 0000003313 00000 n Results are considered indeterminate if (mitogen -- nil) < 1.5 IU, which might be observed among Results generally indicate the following: Less than 30 mg of protein is normal . 21 E 69th Street.

All screen positive patients are retested in duplicate prior to reporting. latent. Negative QFT results do not require confirmation, but results can be confirmed with either a repeat QFT or TST if Available at http://www.cellestis.com. No history of any symptoms. Test Name Result Flag Reference Range Lab . The Nil value represents nonspecific reactivity produced by the patient specimen. http://www.cdc.gov/mmwr/pdf/rr/rr5905.pdf. However, the need for 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. Mitogen- and Antigen-induced Lymphocyte Proliferation Panel Measurement of human lymphocytes proliferative responses to various stimuli is a fundamental technique used to assess their biological status and functions. The TB2 tube also contains a set of TB peptides that induce gamma interferon responses from TB-sensitized CD8+ cytotoxic T lymphocytes. QuantiFERON-TB Gold (QFT) is a simple blood test. If TST is negative, then there is absolutely no issue. stream Peripheral blood mononuclear cells (PBMC) are cultured in vitro with plant lectins (mitogens) such as phytohemagglutinin (PHA) and pokeweed mitogen (PWM).

The test is based on the quantification of interferon-gamma RR-6):1--51. My first test had a TB1-Nil of 0.59, TB2-Nil of 0.02, and Mitogen-Nil of 9.93. It helps to detect Mycobacterium tuberculosis, the bacteria which causes tuberculosis (TB). health-care workers who, after their preemployment assessment, are considered at increased risk for exposure to tuberculosis. tuberculosis is referred to by the manufacturer and in FDA documents as human PPD.
