【摘要】目的： 对 SYSMEX 干化学 UC-3500 及流式 UF-4000 全自动尿液分析仪智能审核规
则和有效性进行验证。方法：收集 2021 年 5 月 14 号至 2021 年 6 月 16 号的门诊新鲜尿液

标本共 303 份，采用双盲法，验证干化学定性结果等级以及尿有形成分数量范围一致性的复
检规则。然后通过再次检测 9206 份尿液标本，对规则有效性进行验证分析。结果：经过统

计分析，得出真阳性率 35.97%（109/303），假阳性率 18.48%（56/303），真阴性率 42.90%
（130/303），假阴性率 2.64%（8/303），复检率 43.56%（132/303）。经验证：镜检率 8.17%

（752/9206），无效审核 0.00%，有效拦截率 93.58%（8615/9206）、仪器无效拦截 0.00%， 一
致性 100%。结论：假阴性率 2.64%（<5%）符合要求，本实验室全自动尿液分析仪的智能

审核规则验证通过。无效拦截率及无效审核率为 0.00%以及一致（100%）性高，本规则有效
性验证通过,不需要进行调整。经仪器筛选需要镜检标本后，提高尿液检验工作的效率，同时

降低复检率，提高临床适用性。

The Validation of Sysmex UC-3500 and UF-4000 automatic urine analyzer intelligent audit
rules and effectiveness

[Abstract] Objective：The intelligent auditing rules and validity of Sysmex dry chemical UC -
3500 and flow UF-4000 automatic urine analyzer were verified. Methods：A total of 303 fresh

urine samples were collected from outpatient clinics 2021 May 14 to June 16 of the 2021.Double-
blind method was used to Set up a review rule for the consistency of the qualitative results of dry
chemistry and the quantitative range of urinary formed components. Results：The results showed

that the true positive rate was 35.97% (109/303) , the false positive rate was 18.48% (56/303) , the
true negative rate was 42.90% (130/303) , the false negative rate was 2.64% (8/303) , the
reexamination reexamination rate was 43.56% (132/303).The microscopic examination rate was

8.17% (752/9206) , the invalid examination rate was 0.00% , the effective interception rate was
93.58% (8615/9206) , the instrument ineffective interception rate was 0.00% , the consistency was
100% were verified. Conclusions: The false negative rate was 2.64%,this meets the requirements,
the intelligent audit rules of the automatic urine analyzer in our laboratory has been verified. The

invalid interception rate and the invalid audit rate are 0.00% and the consistency (100%) is high, the
validity of this rules is verified and No adjustments are required. After screening the specimen
needed by the instrument, the efficiency of urine examination can be improved, and the
reexamination rate can be decreased, so the clinical applicability can be improved.
