Key Findings
In this research study, N- and E- gene multiplex (ddCoV_N and ddCoV_E) RT-ddPCR method is redesigned and optimized to detect SARS-CoV-2 from wastewater samples and compared with the standard nCoV_N2 and E_Sarbeco RT-qPCR assays.

Reporting one-step RT-dPCR (reverse transcription digital PCR ) method based on SARS-CoV-2 ORF1ab, N, and E gene for detecting SARS-CoV-2 from pharyngeal swab samples. RT dPCR uses droplets of samples with as low as 2 gene copies to diagnose COVID-19 positive.
