“…This serves as a quality assurance for the participating laboratory, provision of early warning for systematic problems associated with kits or operations; provision of objective evidence of testing quality; indication of areas that require improvement and to identify training needs, and to improve comparability and harmonized reporting between laboratories despite the use of different laboratory methods. EQAs are used in many different settings 11 , 13 , 26 both to provide a quality statement 9 , 10 , 26 , but also to help guide the reference laboratories in providing the appropriate laboratory tests 9 , 10 , 12 . This paper describes an EQA scheme for S. pneumoniae serotype identification arranged between national reference laboratories that started in June 2005 and is still on-going.…”

“…External quality assessment (EQA) schemes allow laboratories to assess their performance to identify and type a pathogen, even when different methodologies have been used 11 – 13 . The EQA results can also document that laboratory procedures at a certain time point are in accordance with internationally agreed procedures 9 , 10 , 14 .…”

An external quality assessment (EQA) scheme for pneumococcal serotype identification has been performed over a period of 11 years, by a network of European pneumococcal reference laboratories. We report the results from the EQA, and present an assessment of the acceptability and utility of the EQA scheme. Reports from 22 EQA panels distributed in 2005–2016 were analysed. Each EQA panel consisted of seven isolates. A questionnaire including seven questions related to the acceptability and utility of the EQA scheme was distributed to all participating laboratories. Altogether, 154 pneumococcal isolates were tested. Of the 92 serologically distinct serotypes currently defined, 49 serotypes were included in the rounds. Discrepant results were observed in eight EQA rounds, involving 11 isolates (7.1%, 95% CI: 4% to 12%). All participating laboratories reported that the EQA scheme was useful for quality assurance purposes. Our results show that comparable serotyping data can be obtained in different laboratories. The EQA participation helps to keep the typing procedures at a high standard and provides data for accreditation purposes. The EQA is helpful when new technologies are introduced, and reveal limitations of both genotypic and phenotypic methods. Continuation of the presented EQA scheme is planned.
