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.
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.
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.
This report presents the results of an external quality assessment carried out in 2014 to test laboratories’ ability to correctly identify strains of Haemophilus influenzae.
In May 2012 a collection of five strains of Haemophilus spp was sent to 28 participating reference laboratories in the IBD-labnet surveillance network for quality assurance testing. The laboratories were asked to characterise the five strains by performing standard laboratory protocols for the methods usually used by the laboratory for: species identification, biotyping and serotyping by serological methods and/or PCR.
The results of this EQA are published in the this report.
