RESUMO
The hemoglobin A1c (Hb A1c) test is widely used to diagnose diabetes mellitus and monitor glycemic control in patients with diabetes. We evaluated the performance of the ARKRAY ADAMS A1c HA-8180 (ARKRAY KDK, Japan), an automated, HPLC-based Hb A1c analyzer. The ARKRAY ADAMS A1c HA-8180 was evaluated for its linearity and precision and compared to the HLC-723 G7 (Tosoh Corporation, Japan), according to the Clinical and Laboratory Standards Institute's guidelines. The coefficients of variation (CVs) for within-run precision at low and high levels were 0.6% and 0.3%, respectively, and the total CVs at low and high levels were 0.8% and 0.6%, respectively. The coefficient of determination (R2) was 0.9975, with linearity in the range of 3.0-18.5%. A comparison between the ARKRAY ADAMS A1c HA-8180 and HLC-723 G7 revealed a good correlation (r=0.9955) in the range of 4.8-14.6%. The runtime was 57 s per sample. The ARKRAY ADAMS A1c HA-8180 showed good analytical performance and high throughput. Therefore, it is suitable for routine use for clinical measurements of Hb A1c.
