2017年8月2日 · QFT-Plus is an IFNγ release assay, commonly known as an IGRA, and measures the cell-mediated immune response to specific TB antigens in whole blood. The test employs standard phlebotomy procedures using whole blood to make sample collection easy and fast.

QuantiFERON-TB Gold Plus is an in vitro diagnostic test using a peptide cocktail of CD4+ and CD8+ T cell antigens to stimulate cells in heparinized whole blood. Detection of interferon-gamma by enzyme-linked immunosorbent assay (ELISA) is used to identify in vitro responses to these peptide antigens that are associated with Mycobacterium ...

Advanced tuberculosis tests (TB tests) that aid in the detection of latent TB infection can significantly reduce the risk of TB disease and can help prevent new outbreaks from recent transmission. Newer latent TB test kits, known as Interferon-Gamma Release Assays (IGRAs), produce more accurate results than the century-old tuberculin skin test.

LIAISON ® QuantiFERON TB-Gold Plus is an exclusive immunoassay diagnostic solution based on CD8+ T-cell technology for the detection of interferon-y (IFN-y) in human lithium heparin plasma.

QuantiFERON®-TB Gold Plus (QFT-Plus) is a simple blood test that aids in the detection of Mycobacterium tuberculosis, the bacteria which causes tuberculosis (TB). Like its predecessor, QFT-Plus is an interferon gamma release assay, commonly known as an IGRA, and is a modern alternative to the tuberculin skin test (TST).

QuantiFERON-TB Gold Plus Kit provides: Detection of the cell-mediated immune response against M. tuberculosis. Quantitative measurement of the in-vitro INF-response of T cells against three recombinant peptide antigens of mycobacteria

Test Overview : The QuantiFERON TB GOLD PLUS (QFT) blood test measures a person's immune reactivity to M. tuberculosis and can be used as an aid in diagnosing infection. The test should not be used to differentiate latent tuberculosis infection from tuberculosis disease.
