Flowchart of sample selection in study of quantitative SARS-CoV-2 spike receptor-binding domain and neutralizing antibody titers in previously infected persons, United States, January 2021–February 2022. Nonnumeric results are quantitative receptor-binding domain assays with invalid results due to insufficient serum volume, lost sample, or poor reproducibility. NCLS, Nationwide Commercial Laboratory Seroprevalence Survey.
