Micro-Dx™ CE IVD – Results From Multi-Sites Clinical Evaluations Micro-Dx™ is the new kit for the in-vitro diagnosis of microbial pathogens without the need for cultivation. The kit is used with the SelectNA™plus instrument which automatically processes a variety of routine specimens ending up with human DNA depleted, pure DNA from eubacterial and fungal pathogens. Assaying is performed by broad-range 16S and 18S rRNA genes PCR or Real-Time PCR analysis which provides a positive-negative result after 3.5 to 4 hours. Identification of species by Sanger sequencing analysis is completed within another 3 to 4 hours. Here, the results of multi-sites evaluations by routine laboratories are presented which either used results from other molecular tests or culture as reference systems. In total, 409 samples were analyzed using Micro-Dx™ in 3 laboratories from Germany and in one laboratory each from Denmark, France, Switzerland and UK. Samples comprised of a variety of tissues, fluid biopsies and swabs. The evaluations indicated acceptable diagnostic performance of Micro-Dx™ with mean values of sensitivity of 89%, specificity of 85%, PPV of 76%, NPV of 88%, and concordance of 85%. In 7 of the 9 evaluations, Micro-Dx™ identified pathogens in reference-negative samples. By its automated sample extraction, Micro-Dx™ contributes greatly to the demand for a reduced hands-on workflow in routine molecular pathogen testing.
