This report provides an analysis of the EQA performance of laboratories in the 28 EU/EEA countries in relation to the detection/isolation, identification, enumeration and quantification of Legionella spp. and the further characterisation of L. pneumophila, by serogrouping and sequence-based typing, from both clinical and environmental samples, where applicable.
This report presents the results of the ninth round of the external quality assessment (EQA-9) scheme for typing of Shiga toxin-producing Escherichia coli (STEC).
This report presents the results of the fourth round of the EQA on antimicrobial susceptibility testing (AST) for national public health laboratories for Campylobacter (Campylobacter EQA4-AST) within the Food‐ and Waterborne Diseases and Zoonoses Network (FWD-Net). The objectives of this EQA4-AST were to determine the accuracy of quantitative AST results reported by participants; to identify common laboratory problems related to the guidance in the EU protocol, and to assess the overall comparability of routinely collected AST data from national public health reference laboratories across Europe.
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.
This report presents the results of the third round of the external quality assessment (EQA) on antimicrobial
susceptibility testing (AST) for national public health laboratories on Salmonella (hereafter Salmonella EQA3-AST).
ECDC is supporting a large number of targeted External Quality Assessment (EQA) schemes with voluntary participation by reference or primary laboratories, which are active members of EU surveillance networks.
External quality assessment (EQA) is an essential part of any laboratory-based surveillance system, allowing for the monitoring of performance and comparability of results from participating laboratories, identification of potential issues, and deployment of resources and training where necessary.
