The participating blood donors were informed about the study and received the result of their SARS-CoV-2 antibody test. The study was approved as a surveillance study in all five Danish administrative regions and the appropriate institutional forms obtained. Confidence intervals for this combined measure were derived via the delta method. Each test week was considered independently and recurring donors could thus be included more than once. In addition, the estimated cumulative incidence of SARS-CoV-2-infected individuals was weighted to ensure that the age, sex, and regional distribution of the donors each week and within each strata matched that of the general population. Stratified versions of the test week-specific estimates were generated, stratified by sex, age (age strata: 17–35, 36–50, 51–60, and 61–72 years), administrative region, and whether the donor had previously been infected. The November seroprevalence was subtracted to both adjust for the assay specificity and to remove signals from earlier infections. The estimated cumulative incidence of SARS-CoV-2-infected individuals in the background population was then calculated as the difference between the anti-N IgG seroprevalence in November and the seroprevalence for the given test week divided by the observed test sensitivity. The anti-N IgG antibody seroprevalence among blood donors by test week was calculated in a Poisson model. The specificity of the assay was previously assessed in a national validation in the laboratories also analysing the current samples (Abbott Alinity: 99♳% (98♳–99♷) Abbott Architect: 99♵% (98♵–99♸)). We additionally tested donations from the first two weeks of November 2021, before Omicron was introduced into Denmark, thus representing a baseline for tracking subsequent increased seroprevalence consequent to Omicron infections. The anti-N IgG antibody measurements were performed over six rounds with sampling on odd-numbered calendar weeks during the study period. The anti-N IgG antibody result was interpreted as positive if the signal to cut-off (S/CO) ratio was above 1♴ as recommended by the manufacturer.

The Abbott SARS-CoV-2 anti-N IgG assay is based on the chemiluminescent microparticle immunoassay (CMIA) technique and was performed on automated Architect or Alinity systems.

In the current study, we used the SARS-CoV-2 IgG assay (Abbott Diagnostics, Abbott Park, Illinois, United States) to identify infection-induced immunity.
