OBJECTIVES: The influences of Hb variants on HbA(1c) values can cause mismanagement of diabetes; therefore, the effects of Hb E, H, and G-Taichung variants were evaluated. DESIGNS AND METHODS: HbA(1c) values of 2105 samples, including 37 samples with Hb E, H and G-Taichung variants identified by Hb electrophoresis and the PCR sequence, were evaluated by the ion-exchange (Bio-Rad Variant II Turbo analyzer) and boronate affinity (Primus CLC 385 analyzer) high performance liquid chromatography (HPLC) methods. RESULTS: In the patients with the Hb E and H variants, their HbA(1c) values determined by ion-exchange HPLC were significantly higher than those by boronate affinity HPLC. However, there were no significant differences of the HbA(1c) values in the patients with the Hb G-Taichung variant. CONCLUSIONS: The HbA1c levels might be interfered by the Hb E and H variants, but not the Hb G-Taichung variant, measured by the Bio-Rad Variant II Turbo analyzer.
