病人数据用于尿分析室内质控的四种方法学评价及临床应用

Evaluation of Four Methods For Inpatient's Data on Internal Quality Control of Urinalysis and Application

收集了52个工作日1626例住院病人尿常规标本十个项目的检测结果，分别采用四种统计方法对每日各项目的阴性率（PN）进行了统计学处理，计算出95％的置信区间并对其进行了方法学评价，结果表明：八个定性试验项目宜采用百分位数法进行统计学处理，比重（SG）和尿酸碱度（PH）宜采用正态公布法处理，运用该法绘制的各项目质控图连续观察了26个工作日的尿分析结果，效果满意。

Data of ten items from routine urinalysis in 1626 inpatients were collected. The negative rate and confi-dence limit of 95 percent to each item were calculated by four statistic methods and evaluated. The result showed that percentile was suit to eight qualitative items and normal distribution should be adopted on SG and PH. Uri-nalysis data of each item on their plot for quality control are satisfactory.
