antibody testing

It seems like SARS-CoV-2 antibody tests should be pretty simple. Tests consist of SARS-CoV-2 antigens on a plate. If a person has antibodies for SARS-CoV-2, their antibodies bind to the antigens, and the test reads as positive. However, it is possible to get a false positive if some other antibody can bind by coincidence to the antigen.

There is evidence the first known coronavirus-related death in the United States occurred on Feb. 5. What does this mean for individuals, like Kelly Bradbury, who were sick at that time but unable to get tested? 


Many groups are working to develop antibody tests as part of the effort to aid doctors in the fight against COVID-19, including a northern Utah biomedical company.
