Erroneous HbA1c measurements in the presence of β-thalassemia and common Chinese hemoglobin variants

Abstract

β-Thalassemia can cause errors in HbA1c determination using the Variant II Turbo system. HbE heterozygosity or HbE homozygosity also complicated HbA1c measurements. The Capillarys 2 Flex Piercing system detected all Hb variants and HbA1c in patients with β-thalassemia and could provide measurements with high accuracy.
