This article needs to be updated.(May 2020) |
This article contains a lot of positive statements with no indication that most of them apply to all automated real-time PCR tests, not just this proprietary brand (see Cepheid (company)). The difference between a GeneXpert MTB/RIF test and a GeneXprt test for anything else is swapping out a single reagent, so it would be repetitive to have a separate article for each one (see Cepheid (company)#System). The omission of this context means that it contains promotional content. (May 2022) |
The Xpert MTB/RIF is a cartridge-based nucleic acid amplification test (NAAT) for rapid tuberculosis diagnosis and rapid antibiotic sensitivity test. It is an automated diagnostic test that can identify Mycobacterium tuberculosis (MTB) DNA and resistance to rifampicin (RIF). It was co-developed by the laboratory of Professor David Alland at the University of Medicine and Dentistry of New Jersey (UMDNJ),[1] Cepheid Inc. and Foundation for Innovative New Diagnostics, with additional financial support from the US National Institutes of Health (NIH).[2]
In December 2010, the World Health Organization (WHO) endorsed the Xpert MTB/RIF for use in tuberculosis (TB) endemic countries.[3] The announcement followed 18 months of assessing its field effectiveness in tuberculosis, MDR-TB, and TB/HIV co-infection.[4] The test may enable the diagnosis of TB in patients likely to be missed by traditional tests.[4][5]
According to the Centers for Disease Control and Prevention (CDC) in 2015,[6] the Xpert MTB/RIF test was "revolutionizing TB control by contributing to the rapid diagnosis of TB disease and drug resistance. The test simultaneously detects Mycobacterium tuberculosis complex (MTBC) and resistance to rifampin (RIF) in less than 2 hours. In comparison, standard cultures can take 2 to 6 weeks for MTBC to grow and conventional drug resistance tests can add 3 more weeks."[6]
