Participation in the scheme
Committees & Advisory Groups
Steering Committee/Specialist Advisory Group
The scheme is organised with a formal Steering Committee ( UK NEQAS (Clinical Chemistry)) and membership of the UK NEQAS Specialist Advisory Group for Immunoassay. A member of the appropriate National Quality Assurance (NQA) Advisory Panel sits on the Steering Committee and the Specialist Advisory Group.
NQAAP and Joint Working Group
The National Quality Assurance Advisory Panels (NQAAP) are professional groups which have executive responsibility for maintaining satisfactory standards of analytical and interpretative work in laboratories in the UK, whether in the private or in the public sector, in which investigations are performed for the detection, diagnosis or management of disease in humans. The Chairperson of each of the Panels reports to the Joint Working Group (JWG) on Quality Assurance. Details of JWG conditions of EQA participation have been reproduced in the scheme manual and are available on the RCPath website.
