Abstract

This study determined the reliability of dipstick urinalysis for detection of protein, glucose, blood and nitrites in non-random urine samples from 300 people aged > 50 years attending a health centre for check-up. The gold standards were fasting blood glucose for glucosuria and the sulfosalicylic acid method for urine protein. Microscopic examination of urinary sediment and urine culture were also performed for positive dipstick results for haematuria and nitrites. The sensitivity, specificity and positive and negative predictive values of the dipstick test for detection of protein were 80.0%, 95.0%, 22.2% and 99.6% and for glucose were 100%, 98.5%, 87.0% and 100% respectively. Dipstick urinalysis can be a reliable screening method for diagnosis of urinary tract infection and diabetes mellitus but not for proteinuria.

摘要

本研究旨在确定尿试纸分析在检测 300 名年龄大于 50 岁的体检人群中非随机尿液样本中的蛋白质、葡萄糖、血液和亚硝酸盐的可靠性。尿糖的金标准是空腹血糖，尿蛋白的金标准是磺基水杨酸法。对于尿潜血和亚硝酸盐阳性的尿试纸结果，还进行了尿沉渣和尿培养的显微镜检查。尿试纸试验检测蛋白质的敏感性、特异性、阳性预测值和阴性预测值分别为 80.0%、95.0%、22.2%和 99.6%，检测葡萄糖的敏感性、特异性、阳性预测值和阴性预测值分别为 100%、98.5%、87.0%和 100%。尿试纸分析可作为诊断尿路感染和糖尿病的可靠筛选方法，但不能用于蛋白尿的诊断。
