Corona Virus Disease 2019 (COVID-19) is a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This pandemic has brought the world to a standstill and threatened human lives. Many methods are known to date to detect this virus. Due to their relative sensitivity, polymerase chain reaction (PCR)-based assays are the most frequently applied and considered the gold standard. However, due to the rapid mutation rate of the viral genome and the emergence of new variants, existing protocols need to be updated and improved. Designing a fast and accurate PCR-based assay is of great importance for the early detection of this virus and more efficient control of the spread of this disease. This study describes a fast, reliable, easy-to-use, and high-throughput multiplex SARS-CoV-2 RT-PCR detection method. The assay was designed to detect two viral genes ( N and RdRP ) and a human gene ( RP ) simultaneously. The performance and the sensitivity of the assay were tested in 28 SARS-CoV-2 positive samples and compared with commercial kits, which showed 100% positive percent agreement with a limit of detection (LOD) value of 1.40 and 0.81 copies/µL or 35.13 and 20.31 copies/reaction for RdRP and N genes, respectively. The current assay is found accurate, reliable, simple, sensitive, and specific. It can be used as an optimized SARS-CoV-2 diagnostic assay in hospitals, medical centers, and diagnostic laboratories as well as for research purposes.
