摘要
[目的]鉴别干化学分析法检测尿液尿潜血的假阳性。[方法]收集尿潜血+^+++号、UF-100尿沉渣分析仪检测尿红细胞<25/μL、镜检尿红细胞阴性的尿液200份,取0.5 mL试管中,用免疫胶体金法检测,阳性者为真阳性,阴性者为假阳性。[结果]假阳性为84例,占42%;真阳性为116例,占58%。[结论]免疫胶体金法可以鉴别尿潜血的假阳性。
[Objective] To distinguish false positive of urine occult blood by urine analyzer.[Methods] We collected 200 urine samples with occult blood(+)^(+++),RBC less than 25/μL detected by urine sediment analyzer and RBC negative by microscope.We took 0.5 mL urine into test tubes and detected occult blood by immunological colloidal gold method as gold standard.[Results] False positive cases were 84,taking up to 42% while true positive cases 110(58%).[Conclusion] Immunological colloidal gold method can be used to distinguish false positive of urine occult blood.
