25 EQA organisers of 20 countries agreed to participate in the fourth “EurAAA1c” project. The name and logo of the project had been changed to EurAAA1c to acknowledge the participation of EQA organisers in Asia, America and Africa. The project is now called EurA1c.
16 EQA organisers used fresh whole blood samples and 13 organisers used lyophilised hemolysate samples (4 organisations used both fresh and lyophilised samples). In October 2019 the fresh whole blood samples were sent to the participants. From November 2019 up to April 2020 the lyophilised samples are assayed by the participants.
2020: EurA1c 2020 Report
IEQAS has been collaborating with this project annually since it was established in 2016, involving EQA providers in over 17 predominantly European countries. Two samples were distributed simultaneously via multiple EQA organisers to establish a European-wide picture of HbA1c performance. The project is part of the IFCC Committee for Education in the Use of Biomarkers in Diabetes (C-EUBD).The success of this EurA1c project highlights the importance of EQA in driving analytical quality improvement and follows on from the successful 2011 implementation of International Standardisation of HbA1c in Ireland.
