QuantiFERON-TB Gold (Cellestis Limited, Carnegie, Victoria, Australia) is an interferon gamma release assay that was approved by the US Food and Drug Administration in 2005 for the diagnosis of tuberculosis infection and for the screening of immigrants to the United States and healthcare workers. 10. QuantiFERON-TB Gold identifies latent tuberculosis infection better than the tuberculin skin.
QuantiFERON-TB Gold Plus is an indirect test for M. tuberculosis infection (including disease) and is intended for use in conjunction with risk assessment, radiography, and other medical and diagnostic evaluations. Limitations. A negative QFT-Plus result does not preclude the possibility of M. tuberculosis infection or tuberculosis disease: false negative results can be due to stage of.
The QuantiFERON-TB Gold blood test will come back with either a positive or a negative result. In some people, an inconclusive result may occasionally occur. A negative result means that there is not active or latent tuberculosis infection.

This test was approved by the US Food and Drug Administration (FDA) in 2005.
QuantiFERON-TB Gold In-Tube (QFT-GIT) assay is an IGRA that uses ELISA to quantify interferon-gamma release in vitro when patient’s whole blood is exposed to a cocktail of 3 mycobacterial proteins (ESAT-6, CFP-10, and TB 7.7).
A negative QuantiFERON-TB Gold result does not preclude the possibility of Mycobacterium tuberculosis infection or tuberculosis disease. False negative results can be due to the stage of infection (eg., specimen obtained prior to development of cellular immune response), co-morbid conditions that affect immune functions, or other individual immunological factors. Additionally, heterophile.
