探讨尿碘检测中尿样留取的影响因素

To Investigate the Influencing Factors of Urine Retention in Urinary Iodine Examination

目的探讨分析尿碘检测中尿样留取的影响因素。方法选取我院2017年4-6月随机抽取送检尿液标本135例为研究对象,将其随机分为A、B、C、D、E,5组各27例,5组人员采用不同方式检测,A组(ADA检测法与国标法检测)、B组(不同容器检测对比)、C组(不同采集时间检测对比)、D组(不同保存时间检测对比)E组(大量饮水与晨尿对比),分析其影响结果。结果国标法与ADA检测法尿碘值检测(P>0.05)。玻璃管尿碘值显然高于塑料管(P<0.05)。空腹晨尿与餐后6 h尿液尿碘值(P>0.05)。新鲜晨尿尿碘值显然高于冷冻2月后尿碘值(P<0.05)。新鲜晨尿尿碘检测值显然高于大量饮水后尿碘检验值(P<0.05)。结论两种检测方法相比较并无显著差异,但尿样采集、保存等取留方式对尿碘检验结果存在一定影响。

Objective To investigate the influencing factors of urine sampling in urinary iodine examination. Methods In our hospital from April to June 2017 were randomly selected from urine specimens of 135 cases as the research object, which were randomly divided into A, B, C, D E, 27 cases in each group. The 5 groups using different test method, group A(ADA detection and GB test) and group B(contrast different container detection) and C group(comparison of different acquisition time detection) and group D(different preservation time, detection, contrast) Group E(large amount of water compared with morning urine) Analysis of the impact of the results. Results National standard method and ADA test method, urine iodine value test(P>0.05). The glass tube urine iodine was obviously higher than that of the plastic tube(P<0.05). Fasting morning urine and urine iodine value at 6h after meal(P>0.05).The urine iodine value of fresh morning urine was obviously higher than that after freezing in February(P<0.05).The detection value of urine iodine in fresh morning urine is obviously higher than that of urine after drinking water(P<0.05). Conclusion There is no significant difference between the two methods, but the method of urine collection and preservation has a certain influence on urine iodine test results.
