The freeze dried bead chemistry of the Genedrive® 96 SARS-CoV-2 test is ideally suited for use on high throughput robotic platforms like the Biomek i7. Stable at room temperature for 4 hours after unsealing, many Genedrive® 96 SARS-CoV-2 Kit 96-well plates can be left arrayed and open in the laboratory environment during the set-up process. The ready-to-go nature of the test bead also removes the fluid dispensing steps required in other assays, increasing the overall throughput of the Biomex i7 compared to using a liquid based test set-up. Accordingly, once validated, Beckman Coulter estimates that this new turnkey solution could process circa 1,000 PCR samples per Biomek installed during a standard 8-hour working day, using just a 0.5 full-time-equivalent in technician time for processing.
Genedrive has already completed initial evaluation of Beckman Coulter's RNA extraction chemistry to confirm compatibility with the Genedrive 96 SARS-CoV-2 test. Further work is ongoing to validate clinical saliva samples which are a very relevant sample type for applications such as high volume occupational screening. Beckman's RNAdvance Viral XP has already been listed as an extraction method for swab samples for use with the Centers for Disease Control's EUA-authorized COVID-19 test in FDA's FAQ on testing for SARS-CoV-2.
