First rapid covid19 antigen test got FDA authorization thanks to hard work of FDA's career staff. It works on Quidel Sofia 2 Platform. My article on topic of rapid antigen tests from @CNBC in January cnbc.com/2020/01/26/op-… and from last week's @WSJopinion wsj.com/articles/the-c…
From our recently released testing blueprint we talk about how rapid, antigen based tests that (while not perfect) can allow an easy swab to give readable result right at point of care can fit into a broader strategy to greatly expand testing availability. healthpolicy.duke.edu/sites/default/…
Link to Quidel PR. The assay for SARS-CoV-2 should run on installed base of Sofia 2 machines in many doctor offices, used to screen for flu, strep, RSV. While the antigen tests have lower sensitivity than machines like GeneXpert they're cheap, easy to use businesswire.com/news/home/2020…
How Sofia 2 Works: "One approach is based on use of antibodies that adhere to parts of the virus... called antigens. If virus is present, the antibodies bind to these viral antigens and produce a chemical reaction that signals the presence of an infection" cnbc.com/2020/01/26/op-…
