Evaluation of the novel microarray-based Prove-it™ Bone&Joint assay for direct detection of pathogens from normally sterile body sites in comparison with culture and broad-range bacterial PCR.

The performance of Prove-it™ Bone&Joint, a novel microarray-based assay for direct pathogen detection from clinical samples was assessed. In culture-positive samples, Prove-it™ performed similarly with broad-range bacterial PCR in osteoarticular (sensitivity 62.9% vs. 57.7%) and non-osteoarticular samples (54.6% vs. 56.8%). Prove-it™ is a rapid tool providing preliminary results while awaiting culture results.
