National Serological Panel

The National COVID-19 Serological Panel sought to determine the proportion of the population residing in Portugal that developed antibodies for the SARS-CoV-2 virus by performing and analyzing serological tests to estimate the prevalence of the infection. This study encompassed a total sample of 12 thousand volunteers, grouped by region and age group.

This project joined two groups of people with different skill sets: on one hand, epidemiologists, immunologists, microbiologists, and virologists from the Instituto de Medicina Molecular and Faculty of Medicine of the University of Lisbon and on the other, Statistics experts from PORDATA, responsible for the sample calculation. Blood collection and serological testing were carried out at the Germano de Sousa Laboratory Medicine Center, also a partner in this study, with its 314 testing points spread across the 102 participating municipalities.

This study was promoted by the Instituto de Medicina Molecular (iMM) and funded by Francisco Manuel dos Santos Society (SFMS) and Jerónimo Martins Group.
