Abstract

Here, we describe a serological enzyme-linked immunosorbent assay for the screening and identification of human SARS-CoV-2 seroconverters. This assay does not require the handling of infectious virus, can be adjusted to detect different antibody types in serum and plasma and is amenable to scaling. Serological assays are of critical importance to help define previous exposure to SARS-CoV-2 in populations, identify highly reactive human donors for convalescent plasma therapy and investigate correlates of protection.

  • The ELISA was validated with 910 prepandemic serum samples, 174 PCR-defined SARS-CoV-2 case sera, and a five-sera NIBSC panel.

    “We validated a widely used enzyme-linked immunosorbent assay (ELISA) for SARS-CoV-2 IgG (15) with 910 serum samples from the prepandemic period and 174 sera from polymerase chain reaction (PCR)–defined SARS-CoV-2 cases, and a well-characterized five-sera panel from the National Institute of Biological Standards and Control (NIBSC) in the UK.”
  • The RBD and whole-spike ELISA responses were highly correlated, with very little interassay variation.

    “As previously noted (15), the RBD and whole-spike ELISA responses were highly correlated (fig. S3C), with very little interassay variation (fig. S4).”
  • The common cold coronavirus HCoV-229E generates antigenic variants that resist older sera yet stay sensitive to current sera.

    “but the common cold coronavirus HCoV-229E evolves antigenic variants that are comparatively resistant to the older sera but remain sensitive to contemporaneous sera50.”
  • Both the full-length S protein and the RBD itself are immunogenic and induce a strong protective neutralizing antibody response after recognition by the immune system.

    “Both the full-length S protein and the RBD itself are immunogenic and induce a strong protective neutralizing antibody response after recognition by the immune system.62,63”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
