The sensitivity of RFP-resistance which was carried out by Xpert MTB/RIF test was 100. 0% (14/14),while the specificity was 93. 6% (44/47). Conclusion The clinical value of Xpert MTB/RIF testwas superiorto acid-fast staining smear test and mycobacterium culture in upplementary diagnosis...
Performance strongly correlated with smear status and culture time-to-positivity. In patients infected with HIV compared with patients uninfected with HIV Xpert MTB/RIF showed a trend to reduced sensitivity (P = 0.09) and significantly reduced negative predictive value (P = 0.01). The negative ...
Depending on the culture method or CRS as the standard, sensitivity of the Xpert MTB/RIF assay for detection of MTB in pleural effusion, cerebrospinal fluid, thoracic drainage fluid and throat swabs specimens were lower than that of other specimens. According to the experimental results, we have...
目的探讨Gene X-pert MTB/RIF检测对肺结核病诊断的价值.方法选取2020年5月—2021年10月期间在张家港市第一人民医院接受治疗的拟诊断为肺结核病患者113例为研究对象,所有患者均接受Gene Xpert MTB/RIF系统分子检测,结核分枝杆菌(MTB)培养和抗酸染色镜检诊断,以Gene X-pert MTB/RIF系统分子检测结果为观察组,以MTB培...
Sensitivity and specificity of Cobas TaqMan MTB real-time polymerase chain reaction for culture-proven Mycobacterium Tuberculosis: meta-analysis of 27431 specimens from 19 studies. Am J Respir Crit Care Med. 2016;193:A7692.
The Xpert MTB/RIF assay (Xpert) is a rapid test for tuberculosis (TB) and rifampin resistance (RIF-R) suitable for point-of-care testing. However, it has decreased sensitivity in smear-negative sputum, and false identification of RIF-R occasionally occurs. We developed the Xpert MTB/RIF Ult...
Sensitivity and specificity were calculated for the stained smear and GeneXpert according to culture (Gold Standard) as well as for GeneXpert MTB/RIF in both negative and positive microscopy tuberculosis cases. Data’s statistical analysis was performed with SPSS13.0 software. Results Seven hundred ...
With the mycobacterium liquid culture drug sensitivity test as the gold standard, the sensitivity and specificity of Xpert/MTB/RIF for detection of resistance to rifampin was 100.0% and 98.0% , respectively. Conclusion The detection of Xpert MTB/RIF in bronchoalveolar lavage fluid has high ...
