Detection of SARS-CoV-2 RNA by direct RT-qPCR on nasopharyngeal specimens without extraction of viral RNA.
Category: Article Summary
Topic: Testing and Treatment
- In order to circumvent the limited availability of RNA extraction reagents and to reduce the cost and turn-around time of the assay, the authors describe a new protocol for direct RT-qPCR to detect SARS-CoV-2 in nasopharyngeal swabs. The new approach provides higher analytic sensitivity for detection than many other commercial and laboratory-developed methods, and the rate of RT-qPCR inhibition was similar to the standard approach.
