Reverse Transcription Digital PCR (RT-dPCR) enables higher accuracy quantification
The COVID-19 pandemic has drawn heightened concern, with over eleven million positive SARS-CoV-2 cases confirmed worldwide by July 2020.1 RT-qPCR currently serves as the clinical standard for the detection of SARS-CoV-2 viral RNA and subsequent diagnosis of COVID-19. However in a recent study, it was demonstrated that digital PCR (dPCR) provided better sensitivity for rare viral targets and in turn identifying patients who ultimately were diagnosed with COVID-19.2 Reverse transcription digital PCR (RT-dPCR) is a valuable technique which enables improved consistency and lower limits of detection compared to qPCR. Quantification of extremely rare SARS-CoV-2 viral RNA target material is also possible without the need for a comparative standard curve.
The Combinati |Q| SARS-CoV-2 Triplex Assay was designed as a single tube solution for SARS-CoV-2 identification and quantification with an integrated control assay for human gDNA. This assay paired with the true 1-step RT-dPCR workflow of the Absolute Q dPCR platform enables integration of sample digitization, reverse transcription, PCR and data collection into a single instrument and can be completed in approximately 80 minutes.
