SARS-CoV-2 lateral flow assays for possible use in national covid-19 seroprevalence surveys (React 2): diagnostic accuracy study

The sensitivity and specificity of seven new lateral flow immunoassays (LFIAs) that were analysed using sera varied from 69% to 100%, and from 98.6% to 100%, respectively (compared with the two reference standards). None of the LFIAs tested meet the criteria for individual use.
