摘要
目的探讨临床常用防腐剂对尿液电导率测定的影响,以便在特殊情况下需要使用防腐剂防腐且需要测定电导率变化时选择对测定结果影响最小的防腐剂。方法用UF-1000i尿沉渣自动分析仪分别测定60例加了各种防腐剂尿液标本的即时及放置固定时间的尿液电导率。结果添加了甲苯和冰乙酸的尿液电导率无明显变化。添加了浓盐酸和甲醛的尿液电导率有明显变化。结论特殊情况下需要用添加防腐剂的尿液标本检测电导率时可选择甲苯和冰乙酸防腐。
Objective Explore what influence will the preservative have on the conductivity to help choose the preservative when using the preservative to preserve under special circumstance and tesing the preservative which has the mimimum effects on the results of changes the conductivity.Methods Use UF-1000i to test 60 conductivity samples which add different preservatives.Results The conductivity that adds toluene and glacial acetic acid has no obvious changes. The one that adds concentrated hydrochloric acid and formaldehyde has obvious changes.Conclusion When using the urine sample which adds preservative to test the conductivity, toluene and glacial acetic acid is acceptable under special circumstance.
