We compared results for urea concentrations in plasma and serum as measured with the Kimble Blood Urea Nitrogen Analyzer method as the test method with those determined by continuous-flow analysis (AutoAnalyzer 1 method) as the comparison method. We evaluated accuracy and precision for patients' samples, National Bureau of Standards Standard Reference Material, College of American Pathologists Survey Validated Reference Materials, and College of American Pathologists Quality Assurance Service control materials. We found the test method to be more accurate and precise than the comparison method.
我们将用金宝血尿素氮分析仪法作为测试方法测得的血浆和血清中尿素浓度结果，与用连续流动分析法（自动分析仪1法）作为比较方法测得的结果进行了比较。我们对患者样本、国家标准局标准参考物质、美国病理学家协会调查验证参考物质以及美国病理学家协会质量保证服务对照物质的准确性和精密度进行了评估。我们发现测试方法比比较方法更准确、更精密。
