A multicentre evaluation of the urine test strip analyser Super Aution-4220 was carried out in six laboratories. The analytical performance of the instrument with regard to imprecision, linearity, detection limit, drift, carry-over and method comparison was studied. Using the Aution stick 8 test strip the pH, glucose, protein, ketones, bilirubin, blood, urobilinogen and leukocyte esterase were analysed. Specific gravity measurements were performed by refractive index method. Within-run and between-run imprecision determined at three levels of analyte were good. No carry-over was observed. Obtained results were linear through all the described analytical range. No significant drift was detected. Method comparison with some quantitative methods was performed and showed a good correlation with most of the analytes. The study of interferences showed minor interferences by common therapeutic drugs with the measurement of some analytes. During the assessment period of about 6 months no breakdown occurred in any laboratory. The Super Aution urine analyser appeared to be a highly automated analyser of urinary test strips. The operation was simple and the maintenance required only a few minutes a day.
在六个实验室对尿液试纸分析仪Super Aution - 4220进行了多中心评估。研究了该仪器在不精密度、线性、检测限、漂移、携带污染和方法比较方面的分析性能。使用Aution stick 8试纸条分析了pH值、葡萄糖、蛋白质、酮体、胆红素、血液、尿胆原和白细胞酯酶。通过折射率法进行比重测量。在三种分析物水平下测定的批内和批间不精密度良好。未观察到携带污染。在所有描述的分析范围内获得的结果呈线性。未检测到明显漂移。与一些定量方法进行了方法比较，结果表明与大多数分析物具有良好的相关性。干扰研究表明，常见治疗药物对某些分析物的测量存在轻微干扰。在约6个月的评估期内，任何实验室均未出现故障。Super Aution尿液分析仪似乎是一种高度自动化的尿液试纸分析仪。操作简单，每天只需几分钟进行维护。
