Development of a reagent kit for the qualitative detection of SARS-CoV-2 virus RNA in naso- and oropharyngeal swabs by real-time RT-PCR.

The coronavirus infection continues to spread around the world. In this regard, the purpose of this work was: to develop a set of reagents for the qualitative detection of SARS-CoV-2 virus RNA. The set was developed by CJSC «Ecolab», 20 positive samples were used to develop the kit. The research method consisted of several stages: isolation of SARS-CoV-2 RNA, RNA reverse transcription reaction and PCR amplification of cDNA with simultaneous detection of the result in real time. The main characteristics of the kit: analytical sensitivity - 100%, specificity - 100%, accuracy - 100%. Thus, our method for diagnosing a new coronavirus infection based on real-time RT-PCR makes it possible to qualitatively and quickly detect betacoronavirus RNA in clinical material from patients and healthy individuals with suspected coronavirus infection and other symptoms of SARS.
