TL;DR: There is a firm and reproducible link between the IFCC RM and DCM HbA(1c) values.
Journal ArticleDOI
Approved IFCC reference method for the measurement of HbA1c in human blood.
Jan-Olof Jeppsson,Uwe Kobold,John R. Barr,Andreas Finke,Wieland Hoelzel,Tadao Hoshino,Kor Miedema,Andrea Mosca,Pierluigi Mauri,Rita Paroni,Linda M. Thienpont,Masao Umemoto,Cas Weykamp +12 more
TL;DR: The new reference method has been approved by the member societies of the International Federation of Clinical Chemistry and Laboratory Medicine and will be the basis for the future uniform standardization of HbA1c routine assays worldwide.
Journal ArticleDOI
Proficiency Testing/External Quality Assessment: Current Challenges and Future Directions
TL;DR: PT/EQA provides substantial value to the practice of laboratory medicine by assessing the performance of individual laboratories and, when commutable samples are used, the status of standardization or harmonization among different measurement procedures.
Journal ArticleDOI
The IFCC Reference Measurement System for HbA1c: A 6-Year Progress Report
Cas Weykamp,W. Garry John,Andrea Mosca,Tadao Hoshino,Randie R. Little,Jan-Olof Jeppsson,Ian Goodall,Kor Miedema,Gary L. Myers,Hans Reinauer,David B. Sacks,Robbert Slingerland,Carla Siebelder +12 more
TL;DR: A sound reference system is in place to ensure continuity and stability of the analytical anchor for HbA(1c), and the reproducibility at laboratories using CE was better.
Journal ArticleDOI
Influence of hemoglobin variants and derivatives on glycohemoglobin determinations, as investigated by 102 laboratories using 16 methods.
TL;DR: Influences of hemoglobin (Hb) variants and derivatives and Hb derivatives on results of glyco-Hb assays by 102 laboratories using 16 different methods were investigated and correct interpretation of results from patients with decreased erythrocyte half-life requires previous knowledge on this condition.
