A novel approach to external quality assessment (EQA) using the Internet mimics the diagnostic situation so that multiple tests can be requested and EQA cases can be 'tailor made' to address a specific chromosome syndrome, disease, or clinical dilemma. The web-based EQA system was trialled on a large UK EQA scheme, UK NEQAS for Clinical Cytogenetics. It has also been used to implement a new Cytogenetics European Quality Assessment scheme, CEQA, set up with the intention of providing laboratories in countries without access to a local EQA scheme the opportunity of participation in EQA. Overall, Internet-based EQA allows for a varied EQA programme. Poor performance was detected in both CEQA and UK NEQAS constitutional EQA schemes and also in the UK NEQAS oncology EQA scheme. The Internet-based EQA overcomes submission delays due to international surface mail. There is also a reduction in administration and assessors' time compared to a retrospective EQA involving the submission of unique cases for EQA assessment, as participants analyse the same three Internet-based EQA cases simultaneously. Many EU27 (EU member states) laboratories still do not participate in their national EQA schemes, so until EQA participation becomes mandatory as a component of compulsory laboratory accreditation, the quality of laboratory diagnostic service is unpredictable.
