Dr. Erna Lenters-Westra is devoted to her research in the field of glycated haemoglobin (HbA1c) for the Clinical Chemistry Department at Isala (Zwolle, the Netherlands). Isala partners with Queen Beatrix Hospital (Winterswijk, the Netherlands), which is the European Reference Laboratory for Glycohemoglobin and is amongst other things, responsible for creating the IFCC secondary reference materials which are the foundation for the global standardization of HbA1c. She has been involved in HbA1c standardization since 1995 and was a member of the IFCC Task Force on implementation of HbA1c standardization. Dr. Lenters-Westra also functions as an HbA1c consultant for most of the major diagnostic manufacturers and the IFCC Committee on the Education in the Use of Biomarkers in Diabetes (C-EUBD). Dr. Lenters-Westra has been published many times in recent years – some of her publications include extensive evaluations of Point-of-Care (POC) testing devices for acceptability in monitoring HbA1c and diagnosis of diabetes, investigation of biological variation as well as statistical models to properly evaluate quality targets for HbA1c instrumentation. She holds a PhD in medicine from the University in Groningen (Groningen, the Netherlands).
