The Rheonix COVID-19 MDx Assay is a fully automated test that enables detection of SARS-CoV-2, the virus that causes COVID-19, directly from respiratory samples. The test is designed to operate on the Rheonix Encompass MDx workstation, and requires no technician involvement after samples are loaded onto the workstation. The sample-to-answer test will facilitate same-day test results for low- and medium-throughput laboratories, allowing for more rapid decisions regarding isolation and treatment of infected patients.
