Comparison of three multiplex real-time PCR assays for detection of enteric viruses in patients with diarrhea

In this study, the usability and performance of three commercially available multiplex real-time RT-PCR assays for the detection of major enteric viruses were investigated. In total, 481 fecal specimens were analyzed using the Allplex™ GI Virus Assay, the Rida®Gene Viral Stool Panel I, and the FTD Viral Gastroenteritis. The overall agreement between the assays was 99.9%. Despite convergent analytical performance, differences between the multiplex RT-PCR assays were apparent when considering their suitability for routine diagnostics.
