Abstract

Evaluation of the Fluorotype MTB Assay for the Rapid and Reliable Detection of Mycobacterium Tuberculosis in Respiratory Tract Specimens by Ulrich Eigner, Anke Veldenzer, M. Holfelder

We performed the first evaluation study of the new FluoroType MTB assay, a HyBeacon based nucleic acid amplification test for the direct detection of Mycobacterium tu-berculosis in respiratory tract specimens. Using mycobacterial culture as a refer-ence, 661 specimens were tested. Sensitivity and specificity were 95.1% and 96.4% for all specimens, sensitivity was 100% for smear-positive and 84.6% for smear negative specimens, respectively. The FluoroType MTB assay showed fast and accurate results within 3 hours, including DNA extraction.
