| 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。 |

| Abstract: |
| ［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. |
