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.
In July 2014, a panel of three strains of Streptococcus pneumoniae and two simulated samples of cerebrospinal fluid was sent to 30 reference laboratories in the IBD-labnet surveillance network for quality assessment testing. This report summarises the diagnostic results submitted by the participating laboratories.
ECDC promotes the performance of external quality assessment (EQA) schemes, in which laboratories are sent simulated clinical specimens or bacterial isolates for testing by routine or reference laboratory methods. EQA schemes, or laboratory proficiency testing, provide information about the accuracy of different characterisation and typing methods as well as antimicrobial susceptibility testing (AST) and the sensitivity of the methods in place to detect a certain pathogen or novel resistance patterns.
