A simplified SARS-CoV-2 detection protocol for research laboratories

Widespread testing is required to limit the current public health crisis caused by the COVID-19 pandemic. Multiple tests protocols have been authorized by the food and drugs administration under an emergency use authorization (EUA). The majority of these protocols are based on the gold-standard RT-qPCR test pioneered by the U.S. Centers for Disease Control and Prevention. However, there is still a widespread lack of testing in the US and many of the clinical diagnostics protocols require extensive human labor and materials, such as RNA extraction kits, that could face supply shortages and present biosafety concerns. Given the need to develop alternative reagents and approaches to allow nucleic-acid testing in the face of heightened demand and potential shortages, we have developed a simplified SARS-CoV-2 testing protocol adapted for its use in laboratory research with minimal molecular biology equipment and expertise. The protocol requires minimal BSL1 biosafety level precautions and facilities.
