摘要
目的 考察尿碘在线消化—流动注射自动分析装置应用中的可靠性。方法 采集 3 5名学生的日间尿样 ,分别按照国家标准方法 (WS/ T10 7-1999)与尿碘自动分析装置的操作说明进行测定 ,并对自动分析装置的性能进行检验。结果 2种方法的尿碘中位数基本相同 ,频数分布一致 ,经配对 t检验 ,2种方法差异无显著意义(P >0 .5) ,尿碘自动分析装置直接测定尿样碘线性范围为 0～ 10 0 0 μg/ L,重现性好 (RSD<3 % ,n =6) ,抗干扰能力良好 ,分析频率每小时可达 70个 ,工作强度下降较大。结论 尿碘在线消化—流动注射自动分析装置具有操作简便、快速、测定灵敏、重现性好和准确特点 ,在上述方面较国家标准法有较大进步 ,很适合推广应用。
Objective To test the reliability of on-line digestion-flow injection automatic analysis device in the assay of urinary iodine (UI).Methods Thirty-five students daytime urine samples were collected,and determined by both national standard method (WS/T107-1999) and on-line digestion-flow injection catalysis spectrophotography method of UI automatic analysis device (UIAAD) respectively.The performance of UIAAD is tested and verified.Results The median and the frequency distribution of UI determination results by UIAAD method are in good agreement with those obtained by national standard method,the two methods have no significant difference through paired comparison t-test(P>0.5).The UIAAD method has good repeatability (RSD<3%,n=6) and ability of interference-resisting,the linerar range is 0~1000 μg/L,the frequency of analysis is 70 samples per hour,fairly large descends the working intensity.Conclusions This UIAAD has the advantages of being simple,rapid,precise and accurate for UI determination,and can be useful for surveillance of iodine deficiency disorders.
