Proficiency testing

Proficiency testing (PT) or external quality assurance (EQA) is essential for accreditation and good quality assurance programmes.

The EURL regularly provide PT distributions for the NRLs covering hepatitis A virus and norovirus genogroups I and II in different food matrices (e.g. raspberries, leafy greens and bivalve molluscan shellfish). Please be aware that the number of PTs from the EURL may not be satisfactory for maintaining accreditation for ISO 15216.

Invitations and instructions will be found under respective year for each PT.
