“…We evaluated the analytical and diagnostic performances of two one-step real-time reverse-transcription PCR assays for detecting respiratory viruses: the AdvanSure RV-plus real-time PCR assay (AdvanSure; LG Chem, Seoul, Korea) and the Real-Q RV II Detection assay (Real-Q RV II; BioSewoom, Seoul, Korea). The AdvanSure assay can simultaneously detect 15 respiratory viruses, including influenza (INF) virus types A and B; respiratory syncytial virus types A and B; parainfluenza virus (PIV) types 1, 2, and 3; adenovirus (ADV); human metapneumovirus; human bocavirus; coronavirus (CoV) OC43, 229E, and NL63; human rhinovirus (HRV); and enterovirus (ETV) [ 1 ]. The Real-Q RV II Detection assay, a revised version of the Real-Q RV Detection assay (BioSewoom) [ 2 , 3 ], can detect PIV 4 in addition to the viruses detectable by the AdvanSure assay; however, the Real-Q RV II cannot differentiate between CoV 229E and CoV OC43.…”
