The results from an external quality control of dry-chemistry instruments are presented. The performance with regard to imprecision was good. With regard to accuracy, the performance was poor for aspartate aminotransferase, creatine kinase, lactate dehydrogenase, triglycerides and uric acid. The inaccuracy of alanine aminotransferase, bilirubin, cholesterol, creatinine, glucose and potassium was comparable to that obtained by hospital instruments using wet chemistry. There were no large differences with respect to quality between Seralyzer and Reflotron. However, Seralyzer users performed more analyses per week, analysed a higher number of constituents and had more experienced operators than the Reflotron users. Reflotron users more often analysed the sample in connection with the consultation. The importance of an established quality control programme for these instruments is underlined.
本文展示了干式化学分析仪外部质量控制的结果。其不精密度方面的表现良好。在准确度方面，天冬氨酸转氨酶、肌酸激酶、乳酸脱氢酶、甘油三酯和尿酸的表现较差。丙氨酸转氨酶、胆红素、胆固醇、肌酐、葡萄糖和钾的不准确度与医院使用湿化学法的仪器所获得的结果相当。在质量方面，Seralyzer和Reflotron之间没有显著差异。然而，与Reflotron的用户相比，Seralyzer的用户每周进行的分析更多，分析的成分数量更多，且操作人员更有经验。Reflotron的用户在会诊时更常对样本进行分析。强调了为这些仪器建立质量控制程序的重要性。
