This document is the first update of the technical report ‘Options for the use of rapid antigen detection tests (RADTs) for COVID-19 in the EU/EEA’. It is intended to facilitate further discussions between Member States on the settings and purpose for which it is appropriate to use RADTs and summarises key considerations for their implementation. Reaching an agreement on settings and performance criteria will be critical for the success of EU/EEA-wide surveillance purposes and for measures related to cross-border travel.
