ABSTRACT
We performed the first evaluation study of the new HyBeacon based FluoroType(®) MRSA assay for the detection of MRSA directly from 617 patient specimens. Using culture as the reference method sensitivity and specificity were higher than 95%. Results were available within 2.5h, including DNA extraction.

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 tuberculosis in respiratory tract specimens. Using mycobacterial culture as a reference, 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.

We evaluated the performance of a PCR-based dipstick assay used in our routine laboratory for the direct detection of Methicillin resistant Staphylococcus aureus (MRSA). 2941 clinical swab specimens were evaluated. Sensitivity and specificity were 94.1% and 98.3%, respectively. The PCR assay combines low instrumentation costs and minor hands-on-time with reliable results for MRSA identification.
