Abstract
We performed basic evaluation studies of the urinary oxalic acid measurement by capillary electrophoresis. This method showed CVs of within-run and between-day precisions of less than 6.0%, and the relative error of dilution linearity was good. The recovery test also showed good results. No effects of hydrochloric acid or ascorbic acid on the urinary oxalic acid measurement were detected. In addition, the correlation of urine samples with high-performance ion chromatography and capillary electrophoresis was good (y = 0.971x + 0.380, r = 0.997, n = 50). This study revealed that this method using capillary electrophoresis is applicable in routine testing.
