Scheme Design

WEQAS is now registered with UKAS and offers a range of EQA schemes for Laboratory Medicine.  For a full list of the schemes offered, including analytes covered and material provided, please see the EQA Program Schemes section.

WEQAS  is now registered with United Kingdom Accreditation Services (UKAS) for compliance with conformity assessment - General requirements for proficiency testing (ISO/CASCO 17043:2010).  Accreditation status - recommended for accreditation.

Samples are distributed to participants on a regular basis, and a window of between two and three weeks, depending on scheme, is allowed for analysis of samples and submission of results. All schemes provide a comprehensive statistical report following processing of a distribution's returns.
