Introduction: The COVID-19 pandemic is still in force, causing global public health challenges and threats. Although vaccination and herd immunity have proven to be the most efficient way to control the pandemic, massive and early testing of patients using the RT-qPCR technique is crucial for constant genomic surveillance. The appearance of variants of SARS-CoV-2 with new mutations can reduce the efficiency of diagnostic detection.

- 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.
