RT-qPCR is used world-wide to test and trace the spread of SARS-CoV-2. “Extraction-less” or “direct” RT-PCR is an open-access qualitative method for SARS-CoV-2 detection from nasopharyngeal (NP) samples with the potential to generate actionable data more quickly, at a lower cost, and with fewer experimental resources than full RT-qPCR. This study provides novel evidence in an international, inter-laboratory ring trial about the practical utility and performance of the direct RT-PCR method with participation by ten laboratories currently experiencing many of the testing limitations. The direct method should be considered as a viable, fit-for-purpose resource to address the growing need for population monitoring during a challenging vaccination roll out and amidst the emergence of increasingly transmissible strains of SARS-CoV-2.
