Within one year's period a model for external quality control of urolithiasis was tested. This model includes specifications concerning precision as well as accuracy derived from diagnostic and therapeutic considerations. The quality indices obtained for precision QI-P and accuracy QI-R confirm that all analytical centres of urolithiasis in the GDR are to be found under the fixed specifications, partially to a considerable extent. Thus all participants indirectly demonstrated that the state of adjustment of instrumentation and thereby the reference factors remain stable for at least one year. The system being continued the specifications of precision (ST 0%) and accuracy (D0) might even be fixed more exactly from an analytical point of view.
在一年时间内，对尿路结石外部质量控制模型进行了测试。该模型包括从诊断和治疗考虑得出的有关精密度以及准确度的规范。所获得的精密度质量指标QI-P和准确度质量指标QI-R证实，民主德国所有尿路结石分析中心均符合既定规范，部分中心在很大程度上符合。因此，所有参与者间接表明，仪器的校准状态以及参考因素至少在一年内保持稳定。如果继续使用该系统，从分析角度来看，精密度规范（ST 0%）和准确度规范（D0）甚至可能会确定得更加精确。
