Timely detection of severe acute respiratory syndrome due to coronavirus 2 (SARS-CoV-2) by reverse transcription quantitative polymerase chain reaction (RT-qPCR) has been the gold- strategy for identifying positive cases during the current pandemic. However, faster and less expensive methodologies are also applied for the massive diagnosis of COVID-19. In this way, the rapid antigen test (RAT) is widely used.

- The study investigates the effectiveness of different virus transport media (VTM) for transporting nasopharyngeal swab samples during the COVID-19 pandemic in Santiago, Chile.
- Five VTM types were compared: DNA/RNA Shield™, NAT, VTM-N, Ezmedlab™, and phosphate-buffered saline (PBS), using RT-qPCR amplification profiles.
- Results indicated that DNA/RNA Shield™ performed best, showing higher fluorescence and lower Cq values, while PBS performed poorly and may hinder accurate sample diagnosis.
