Abstract

The present work validated and evaluated a duplex real-time RT-PCR using specific primers and probes for genes RdRp from SARS-CoV-2 and GAPDH from humans; the latter was used as an endogenous control in all reactions. We evaluated the specificity, the sensitivity, the robustness, the reproducibility, the repeatability, the comparability, and the limit of detection. The predictive positive and negative values (PPV and PNV, respectively) and all the parameters evaluated using our duplex real-time RT-PCR was 100%. The detection limit was 100 copies/μL according to the acceptance criteria established for the validation of this protocol. Our duplex real-time RT-PCR demonstrated to be a good alternative for the diagnosis of COVID-19; in addition, this PCR was used adequately in suspicion of COVID-19, allowing it to control the number of false-negatives.
