QuantiFERON test

QuantiFERON-TB Gold (QFT) is a simple blood test that aids in the detection of Mycobacterium tuberculosis, the bacteria which causes tuberculosis (TB). QFT is an interferon-gamma (IFN-γ) release assay, commonly known as an IGRA, and is a modern alternative to the tuberculin skin test (TST, PPD or Mantoux) QuantiFERON TB Gold test is a basic blood test that helps in the detection of the Mycobacterium tuberculosis which is responsible for causing tuberculosis. The QuantiFERON also called QFT, is an interferon - gamma release assay (IGRA) and is now used as an alternative to the tuberculin skin test (TST, PPD or Mantoux) QuantiFERON-TB Gold Plus (QFT-Plus) is a whole-blood test or interferon-gamma release assay (IGRA) that can measure a person's immune reactivity and aid in diagnosing Mycobacterium tuberculosis infection. It offers advantages over the conventional tuberculin skin test (TST) for diagnosing LTBI. 4,5. Recommended by the Centers for Disease Contro QuantiFERON-TB Gold.

Che cos'è il Quantiferon test? Il Quantiferon TB-2G è un test che si esegue su sangue venoso utile per: la diagnosi differenziale fra tubercolosi polmonare attiva ed infezione da micobatteri non tubercolari; individuare una infezione latente di tipo tubercolare nei soggetti maggiormente a rischio IGRA (Quantiferon-test) Voor de diagnostiek van latente tuberculoseinfectie (LTBI) kan gebruik gemaakt worden van de Interferon Gamma Release Assay (IGRA/Quantiferon test). Bij de afweer tegen tuberculose speelt de T-celafhankelijke immuunrespons de belangrijkste rol. De IGRA berust op het principe dat T-cellen van personen die gesensibiliseerd. QuantiFERON is a powerful Premolecular diagnostic technology that delivers results with high sensitivity, enabling the detection of M. tuberculosis infection even in early or latent stages. The QFT-Plus test employs a peptide cocktail simulating ESAT-6 and CFP-10 proteins to stimulate cells in heparinized whole blood. Detection of IFN-γ by ELISA is used to identify in vitro responses to these. The QuantiFERON®-TB Gold test (QFT-G) is awhole-blood test for use as an aid in diagnosingMycobacterium tuberculosis infection, including latenttuberculosis infection (LTBI) and tuberculosis (TB)disease. This test was approved by the U.S. Food andDrug Administration (FDA) in 2005. How does it work Interferon-Gamma Release Assays (IGRAs) are whole-blood tests that can aid in diagnosing Mycobacterium tuberculosis infection. They do not help differentiate latent tuberculosis infection (LTBI) from tuberculosis disease. Two IGRAs that have been approved by the U.S. Food and Drug Administration (FDA) are commercially available in the U.S

QuantiFERON test interpretation in patients receiving immunosuppressive agents: an alert To the Editor: Latent tuberculosis infection (LTBI) diagnosis in immune-mediated inflammatory diseases is complex because of the patient characteristics and the imperfection of available tests [1]. Functional T-cell assay What is a QuantiFERON test? The QuantiFERON (QFT) blood assay tests for tuberculosis. Patients must get their blood drawn for a QuantiFERON exam. However, QFT candidates receive exam results in 48-72 hours. Compared to PPD wait times, QuantiFERON provides a sizeable advantage The QuantiFERON-TB Gold Plus test uses specialized blood collection tubes, which are used to collect whole blood via venipuncture. Two of the 4 collection tubes contain antigens representing certain Mycobacterium tuberculosis proteins and 2 of the tubes are controls (Nil and mitogen). TB Antigen Tube 1 (TB1) and TB Antigen Tube 2 (TB2) both contain peptide antigens from the Mycobacterium. Le diagnostic de la forme latente se fait par l'intradermoréaction (IDR). Les limites de ce test ont favorisé le développement de tests sanguins plus spécifiques (ne croisant pas avec le BCG).
