摘要 目的:研究晨尿和随意尿标本蛋白与肌酐比值(Pr/Cr)在显著性蛋白尿预测中的作用。方法:选取本院门诊及住院患者82例,分析其晨尿、随意尿标本Pr/Cr与24h尿蛋白定量(Pr24h)的相关性,作出晨尿、随意尿、24h尿标本Pr/Cr的误差条形图和晨尿、随意尿标本Pr/Cr对显著性蛋白尿(Pr24h>0.3g)诊断的受试者工作特征曲线(ROC曲线),并确定诊断界值,计算敏感度、特异度、阳性似然比、阴性似然比。结果:晨尿、随意尿标本Pr/Cr与Pr24h)高度相关;晨尿、随意尿Pr/Cr与其相应蛋白浓度相比,离散程度明显缩小;晨尿、随意尿标本Pr/Cr对显著性蛋白尿诊断的ROC曲线下面积分别为:0.903、0.892,诊断界值分别为:34.3g/mol、34.9g/mol,以此界值计算敏感度、特异度、阳性似然比、阴性似然比分别为:0.864、0.864,0.826、0.783,4.97、3.98,0.165、0.174。结论:晨尿、随意尿标体Pr/Cr是诊断显著性蛋白尿的良好指标,尤其是作为排除非显著性蛋白尿的初筛试验价值更大。
