| 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. |
