Interferon gamma release assay - Wikipedi

Interferon-γ release assays (IGRA) are medical tests used in the diagnosis of some infectious diseases, especially tuberculosis. Interferon-γ (IFN-γ) release assays rely on the fact that T-lymphocytes will release IFN-γ when exposed to specific antigens. These tests are mostly developed for the field of tuberculosis diagnosis, but in theory, may be used in the diagnosis of other diseases. The IGRA test measures the release of a substance called gamma interferon by white blood cells in a sample of blood when the cells are exposed to specific TB antigens. The IGRA test is not performed by all laboratories. The test requires viable white blood cells, so the IGRA blood sample must be received and tested by a laboratory within a.

The IGRA test is used to diagnose TB infection. This is when the TB bacteria is in the body but the person is not experiencing any symptoms suggestive of TB disease IGRA. IGRA's (Interferon-Gamma Release Assays) meten de in vitro respons op antigenen van de Mycobacterium tuberculosis bacteriën die niet aanwezig zijn in het BCG-vaccin noch in de meeste niet tuberculeuze mycobacteriën (NTM).

Bruk av IGRA-test omtales i tuberkuloseveilederen fra Folkehelseinstituttet. IGRA brukes som hovedregel kun til å avklare om pasienten har latent tuberkuløs infeksjon, ikke til diagnose av aktiv tuberkuløs sykdom. Målgruppen for denne testen er personer som har risiko for latent eller aktiv tuberkulose, så som personer fra høyendemiske. Prevalence of positive test data was stratified by age and country of origin. Studies were evaluated using a modified SIGN checklist for diagnostic studies. Data was compared using Fisher's exact test or χ (2) test, where appropriate. Results: Our literature search yielded 51 studies (n = 34 TST, n = 9 IGRA, n = 8 both). Recommendation of LTBI. QuantiFERON ®-TB Gold Plus blood test. Latent tuberculosis infection is a growing concern. In the US, up to 13 million people have latent tuberculosis infection (LTBI). 1 Without treatment, an average 1 in 10 people with LTBI will get sick with TB disease. 2 Testing for and treating LTBI in high-risk patients is the most effective way to prevent this from happening.

Interferon gamma release assay (IGRA) The interferon gamma release assay (IGRA) is a blood test for TB that's becoming more widely available. The IGRA may be used to help diagnose latent TB: if you have a positive Mantoux test ; if you previously had the BCG vaccination - the Mantoux test may not be reliable in these case QuantiFERON®-TB Gold Plus (QFT-Plus) is a 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) Mantoux vs IGRA Test. Since IGRAs are more costly and technically complex to do than the Mantoux test, in their 2011 policy statement, the WHO did not recommend replacing the Mantoux test by IGRAs as a public health intervention in low- and middle-income countries .
