We aimed to compare Xpert Ultra with Xpert for the diagnosis. Although the evidence base regarding the use of the Xpert MTB/RIF assay for diagnosis of pulmonary tuberculosis TB when testing respiratory samples is well established, the evidence base for its diagnostic accuracy for extrapulmonary and sputum-scarce pulmonary TB when testing non-respiratory samples is less clearly defined. A systematic literature search of 7 electronic databases Medline. GeneXpert MTB/RIF assay is a nucleic acid amplification NAA test which simultaneously detects DNA of Mycobacterium tuberculosis complex MTBC and resistance to rifampin RIF i.e. mutation of the rpoB gene in less than. （13 ） 195 はマルチプラットフォームデバイスであり、さま ざまな病原体の検出カートリッジの一つとして Xpert MTB/Rif がある。このカートリッジを使用す ると、溶解・均質化・殺菌処理した検体から約2 時 間で、結核菌群の遺伝子とリファンピシン（RFP）耐. Gene Xpert was negative for all 92 cases that were clinicoradiologically and histopathologically non-TB lesions true negative: 92/92, false positive 0/92. Thus, the sensitivity of Gene Xpert for spinal tuberculosis in our series is 91.18.
Regardless of the Xpert MTB/RIF result, patient specimens should also have mycobacterial culture to ensure isolates are available for drug susceptibility testing and genotyping.

WHO recommends Xpert MTB/RIF as initial diagnostic testing for tuberculous meningitis. However, diagnosis remains difficult, with Xpert sensitivity of about 50–70% and culture sensitivity of about 60%. We evaluated the.
Background: Background.The Xpert MTB/RIF Xpert assay, the first near-patient test for tuberculosis TB, detects Mycobacterium tuberculosis Mtb with a limit of detection LOD of 133 CFU/ml sputum, and detects mutations in the Mtb rpoB gene which cause Rifampicin resistance RIF-R. Rapid Implementation of the Xpert MTB/RIF diagnostic test 5 P a g e 1. Background Earlier and improved tuberculosis TB case detection - including smear-negative disease often associated with HIV - as well as expanded.

Results Gene Xpert MTB/RIF showed sensitivity, specificity and accuracy of 98.15%, 75% and 96.55% respectively in detection of mycobacterium tuberculosis. Regarding rifampicin mono-resistance, it carried the best sensitivity and. The objective of this study was to evaluate the performance of the Gene-Xpert MTB/RIF sputum test for diagnosing pulmonary tuberculosis TB among patients sputum acid-fast bacillus AFB smear.
technologies, owing to their rapidity, sensitivity, and speciﬁcity. One of the latest systems, the GeneXpert MTB/RIF Xpert assay, was evaluated only recently in a large study with pulmo-nary specimens. The Xpert assay uses. 2012/03/14 · Cepheid's Xpert® MTB/RIF delivers results in less than 2 hours, without making demands on expertise, infrastructure or biosafety measures beyond what can be expected in most peripheral. INTRODUÇÃO: Em 2013, no Sistema Único de Saúde, foi implantada uma ferramenta rápida para o diagnóstico da tuberculose TB, o método GeneXpert MTB/RIF, que detecta a presença do material genético do complexo Mycobacterium tuberculosis e a resistência à rifampicina em uma única reação, fornecendo resultados dentro de 2 h.
