External quality assurance scheme for Bordetella pertussis serology 2013
This report presents the results of an external quality assurance (EQA) scheme for Bordetella pertussis serology which was carried out during the summer of 2013. The aim of the EQA was to assess the ability of national reference laboratories from EU/EEA Member States to correctly perform laboratory serodiagnostic tests for pertussis and to identify any laboratories producing results which differed significantly from the values obtained by the majority of participants. Furthermore, the results of the EQA should enable a set of recommendations to be drawn up to improve methodologies and identify areas for training.
A panel of five freeze-dried sera containing different concentrations of anti-PT IgG was prepared with concentrations ranging from undetectable to clinically associated with infection. The panel was blinded and sent to participants who used their own routine diagnostic ELISA assays to determine the anti-PT IgG concentrations. Raw data were then returned for analysis. Twenty-one laboratories from twenty countries agreed to take part in the study and a total of 76 data sets were collected. The results for the data sets indicated that the assays carried out by most of the participants were accurate.
External quality assessment (EQA) of performance of laboratories participating in the European Antimicrobial Resistance Surveillance Network (EARS-Net), 2019
15 Oct 2020 - This report provides an analysis of the external quality assessment (EQA) for the antimicrobial susceptibility testing (AST) performance of laboratories participating in the European Antimicrobial Resistance Surveillance Network (EARS-Net) in 2019. A total of 952 laboratories (1–95 per country) from 30 EU/EEA countries participated in the EQA exercise.
European external quality assessment programme for influenza virus 2018
11 Feb 2019 - Influenza epidemics occur every winter with high impact on disease burden, hospitalisations and excess mortality in countries in the WHO European Region. To understand the characteristics of circulating influenza viruses during seasonal epidemics, virological influenza surveillance is performed and detected viruses are further characterised at national influenza centres (NICs) that are part of the wider network of the WHO Global Influenza Surveillance and Response System (GISRS). External quality assessments (EQAs) are important instruments in assessing the quality of the generated data that are reported nationally and internationally through The European Surveillance System (TESSy).
External quality assessment for the detection of Bordetella pertussis by PCR, 2018
11 Jan 2019 - This report presents the results of the second European Pertussis Laboratory Surveillance Network (EUPert-LabNet) EQA scheme for Bordetella pertussis PCR funded by ECDC on behalf of EUPert-LabNet. The EQA study was conducted between February and March 2018.
