尿碘标准物测定结果的统计分析

The Statistical analysis of the results of standard urinary iodine

目的 采用两种统计学检验方法 ,判定快速尿碘试剂盒法与标准方法的一致性。对同一组尿碘实验平均值与其标准值的比较 ,观测结果有无差异及对判定结果的影响。方法 用正态分布小样本容量的简化检验(A法 )和方差检验 (B法 )来判定两种测定方法所得结果的异同。结果 检验表明 :用 (A法 )对两种测定方法 ,所测标样的平均值进行比较 ,结果无差异。用 (A法 )再次对测定均值与标准值进行比较 ,结果也无差异。为准确评价快速法的测定结果 ,再采用 (B法 )进行统计比较 ,以提高数据质量。结论 应用两种统计学检验方法对同一组实验观察平均值与其标准值的比较结果 ,标样 2快速法结果偏低 ,其它经方差检验测定值与标准值相符。

Objective To judge the consistency of urinary iodine determination between the rapid test kit and standard method with two statistical methods. To compare the average value to standard value of same samples to know if the results have difference and have influence on the judgement.Methods The simplified test of normal distribution (method A) and analysis of variance (method B) were adopted to judge if the two testing methods have variation.Results The results showed that there were no variation in the average values determined by two test methods, and nor the determing values and standard values according to method A. To evaluate the results in fast method, method B was used to improve the data quality.Conclusions Adopting two statistical methods to observe the average values and standard values in the same samples, the results of fast method in sample 2 was lower,but the other ones were equal by method B.
