European Scheme Open to European Blood Transfusion Screening Laboratories
The Blood Proficiency Testing Scheme (B-PTS) is a form of external assessment of quality control management systems that uses inter-laboratory comparisons to determine the performance of blood transfusion screening laboratories responsible for testing individual blood donations. This scheme supplements each laboratory's own internal quality control procedures by providing an external measure of their testing capabilities.
The EDQM designs and organises the Blood Proficiency Testing Scheme according to "ISO/IEC 17043:2010 Conformity Assessment - General Requirements for proficiency testing".
Participation in the scheme provides laboratories with an objective means to assess and demonstrate the reliability of their data. This helps to build mutual trust between European blood establishments, which is an important element of an effective common system for the quality control of blood donations.
Four studies are organised each year.
Who Organises the Scheme and Who Can Participate?
The EDQM organises, co-ordinates and manages the scheme. Following registration, any blood transfusion screening laboratory can participate.
Achievements in 2016
