Distribution of quantitative SARS-CoV-2 antigen results for the five samples of the EQA survey in March for automated immunoassays. Participants could report their results in pg/mL (blue) or TCID50/mL (red). The light blue dot represents the ScheBo SARS-CoV-2 Antigen ELISA while the dark blue dots represent the Lumipulse G SARS-CoV-2 Antigen assay. All TCID50/mL results were obtained by the LIAISON SARS-CoV-2 Ag assay. Five results (three for HCoV 229E and two for the negative sample) indicating 0 pg/mL are not displayed in this diagram.
