I understand there are concerns about conflating serology and diagnostic tests. But the serology tests give useful information about our progress toward endemicity without pandemic. Sure, folks need to understand that these are nucleocapsid antibody tests and that a rate of seroreversion is seen (e.g. 14% peak down to 10% before climbing again last fall), but this matches well with covidestim.org PEI estimates after considering seroreversion. Labeling with type of antibody test would be helpful.
