CLIN CHEM LAB MED:建立了一种多中心分析尿常规分析仪的智能检定标准

2020-01-31 MedSci MedSci原创

尿化学和尿形态元素分析的智能验证标准可以提高结果验证过程的效率,保证测试结果的可靠性。

虽然实验室信息系统(LIS)目前已被广泛应用,但常规尿液分析结果仍需人工验证。我们建立了智能验证标准来执行自动化的验证过程,减少了人工劳动。

研究人员对来自中国北京三家医院的患者共采集了4610例尿液标本。首先,测量了895个样品,建立了UF5000中成形单元参数的参考区间。其次,对2803个样本进行分析,建立智能验证标准(包括微观审核规则和手工验证规则)。最后,使用912个样本来验证智能验证标准的有效性和准确性。采用相衬显微镜进行显微观察。

在干化学分析和形成元素分析之间以及在特定参数(包括血红蛋白(红血球[RBC]),白细胞酯酶(白血球[WBC])和蛋白质(铸件))之间采用结果水平对应关系,以及 仪表标记,我们建立了七个WBC验证规则,八个RBC验证规则和四个强制转换验证规则。 根据显微镜检查结果,通过分析前面提到的预设规则,我们最终确定了七个显微镜检查规则,九个手动验证规则和三个自动验证规则。 镜检率为21.98%(616/2803),假阴性率为4.32%(121/2803),人工验证总率为35.71%(1001/2803),自动验证率为64.29%( 1802/2803)。 验证结果是一致的。

研究结果表明,尿干化学和尿形态元素分析的智能验证标准可以提高结果验证过程的效率,保证测试结果的可靠性。
