Summary 

A total of 900 residual sera from nine laboratories were sampled in week numbers 17-20, 2020, and tested for antibodies against SARS-CoV-2 using a novel in-house assay established at the Department of Immunology, Oslo University Hospital. Based on these measurements, the estimated seroprevalence in the Norwegian population is probably close to 1% (1.0% (95% credible interval 0.1% -2.4%)).
