What Is QuantiFERON-TB Gold Blood Test? - HTQ.

For blood collection options. The QuantiFERON-TB Gold Plus (QFT-Plus) test is an interferon (IFN) -gamma release assay (IGRA) that assesses the cell-mediated immune response to 2 Mycobacterium tuberculosis complex antigens, ESAT-6 and CFP-10, by measuring IFN-gamma levels in plasma. These 2 proteins are absent from all bacille Calmett-Guerin (BCG) strains and from most nontuberculosis.

The QuantiFERON TB Gold In-Tube test is an indirect test for the M. tuberculosis infection which is based upon the measurement of the cell-mediated immune reaction to antigens simulating the mycobacterial proteins CFP-10, ESAT-6, and TB7.7. This combination of three mycobacterial proteins stimulates the patient’s T-cells in-vitro to release interferon-gamma, which then is measured using.

QuantiFERON Testing. The QuantiFERON TB Gold test (QFT-G) is a whole-blood test for use as an aid in diagnosing Mycobacterium tuberculosis infection, including latent tuberculosis infection (LTBI) and tuberculosis (TB) disease. This test was approved by the US Food and Drug Administration (FDA) in 2005.Patients infected with a M. tuberculosis complex organism normally have lymphocytes in their blood that recognise these antigens. This recognition process involves the generation and secretion of the cytokine, IFN-g. The detection and subsequent quantification of IFN-g by enzyme-linked immunosorbent assay (ELISA) forms the basis of this test.QuantiFERON-TB Gold Plus, Blood Advisory Information.
