Due to this lack of comprehensive guidance at the global and European levels, there has been a diverse approach to SARS-CoV-2 testing policies, weakening the potential benefits that serology testing can bring to addressing the challenges posed by the pandemic. Europe is a heterogeneous region that can influence the use and uptake of serology testing. The global challenge demands the generation of reliable and accurate epidemiological information that can timely inform policy making, whether for diagnostic, treatment, and prevention strategies. Serological testing is critical to respond to this demand.
The policy recommendations offered in this paper intend to enable the implementation of SARS-CoV-2 serology testing to support mitigation strategies at the regional, national, and local levels, to build community awareness and guide advocacy strategies. With the situation evolving rapidly, it is important to notice that this paper should be considered a “live” document that must be updated as new evidence emerges.
