The influence of sample freezing at - 80 °C for 2-12 weeks on glycated haemoglobin (HbA1c) concentration assayed by HPLC method on Bio-Rad D-10® auto analyzer.INTRODUCTION
 HbA1c was assayed by ion-exchange HPLC method on Bio-Rad D-10® analyzer.  Storage for up to 12 weeks at - 80 °C with a single freeze/thaw cycle does not affect HbA1c concentrations measured with HPLC method on Bio-Rad D-10® analyzer.
