用Tonks误差计算法建立放射免疫分析的室内质控

INTERNAL QUALITY CONTROL OF RIA WITH TONKS ERROR CALCULATION METHOD

根据放射免疫分析（ＲＩＡ）的方法学特点，以Ｔｏｎｋｓ误差计算法设计了适用于ＲＩＡ的室内质控图。质控图以正常参考范围确定允许误差的大小，该法简单易行、形象直观。以Ｔ３、Ｔ４测定为例，对此法允许误差计算、质控图制作及结果判断做了介绍。

According to the methodology feature of RIA, an internal quality control chart with Tonks error calculation method which is suitable for RIA is designed. The quality control chart defines the value of the allowance error with normal reference range. The method has the simplicity of its performance and directly perceived through the senses. Taking the example of determinating T 3 and T 4,the calculation of allowance error, drawing of quality control chart and the analysis of result are introduced.
