The good field performance of the Abbott RealTime MTB assay makes it valuable for the diagnosis of extrapulmonary tuberculosis in a low-prevalence setting.
XpertMycobacterium tuberculosis/rifampicin (Xpert MTB/RIF) assay has been endorsed by the World Health Organization (WHO) for diagnosis of extrapulmonary tuberculosis (EPTB), while the sensitivity and specificity have not been fully evaluated.
These results demonstrate that the Anyplex MTB/NTM MDR-TB assay is an efficient and rapid method for the diagnosis of pulmonary and extrapulmonary TB and the detection of isoniazid resistance.
We tested consecutive samples from patients suspected of extrapulmonary tuberculosis with Xpert MTB/Rif, evaluated its sensitivity and specificity against solid and/or liquid culture and CGS.
