Description
技术领域
本发明涉及生物技术领域，具体涉及一种尿碘定量检测试剂盒。
背景技术
碘是合成甲状腺急速的必须微量元素，机体摄碘不足或过多都将影响甲状腺功能，造成甲状腺的损伤，导致甲状腺疾病的发生。肾脏是碘的主要排泄器官，且碘90％经尿排出，10％经粪便排出。尿碘水平是直接评价人体碘营养状况的重要指标。尿碘的订量测定为诊断人们是否缺碘、碘摄入是否过量提供了重要的科学依据。
妊娠期缺碘会使得孕妇与胎儿甲状腺合成减少，婴幼儿的体格和智能发育受到孕妇碘营养水平的直接影响。所以孕妇尿碘水平能够有效反映孕妇碘摄入量和新生儿的碘营养状况。孕妇科学合理补碘，切忌盲目补碘。孕妇补碘的重要时期是妊娠前3个月内，由于胚胎早期补碘能够促使儿童的智力发育，预防婴幼儿发生克汀病。妊娠5个月后补碘难，以防止婴幼儿发生智力缺陷。
目前尿碘测定被国内外采用的技术有砷铈催化分光光度法，等离子色谱质谱法和化学发光法，这些方法都需要对样本提前进行消化处理，且消化时间长，耗时长。
发明内容
有鉴于此，本发明旨在提出一种尿碘定量检测试剂盒，以延长小而密低密度脂蛋白胆固醇检测试剂盒的有效时间，增强稳定性。
为达到上述目的，本发明的技术方案是这样实现的：
一种尿碘定量检测试剂盒，所述试剂盒内的检测试剂由尿碘试剂R1，尿碘试剂R2和尿碘校准品组成，所述尿碘试剂R1，尿碘试剂R2和尿碘校准品的组成成分以及浓度如下：
尿碘试剂R1
尿碘试剂R2
尿碘校准品
防腐剂 0.5％，
碘酸钾纯品。
进一步的，所述尿碘试剂R1中的催化剂Ⅰ为过氧化酰氯或过氧化氢钠中的一种，所述尿碘试剂R2中的催化剂Ⅱ为次氯酸钠。
进一步的，所述尿碘试剂R1中的催化剂Ⅰ浓度为0.02mol/L，所述尿碘试剂R2中的催化剂Ⅱ浓度为0.5mol/L。
进一步的，所述尿碘试剂R1和尿碘试剂R2中的防腐剂均为硫柳汞。
进一步的，所述尿碘校准品中的防腐剂为叠氮钠。
相对于现有技术，本发明所述的一种尿碘定量检测试剂盒具有以下优势：
本发明所述的一种尿碘定量检测试剂盒的检测试剂由尿碘试剂R1，尿碘试剂R2和尿碘校准品组成，适用于全自动生化分析仪的检测使用，样本无需提前进行消化处理，可直接用全自动生化分析仪进行测定，样本测定时间仅需10min，大大缩短了检测时间，提高了检测效率。
附图说明
图1为本发明实施例1所述的一种尿碘定量检测试剂盒试剂的线性关系图；
图2为本发明实施例2所述的一种尿碘定量检测试剂盒试剂的线性关系图。
具体实施方式
除有定义外，以下实施例中所用的技术术语具有与本发明所属领域技术人员普遍理解的相同含义。以下实施例中所用的试验试剂，如无特殊说明，均为常规生化试剂；所述实验方法，如无特殊说明，均为常规方法。
下面结合实施例来详细说明本发明。
本发明所述的一种尿碘定量检测试剂盒的检测原理为：
本发明的试剂盒是利用强氧化剂过硫酸铵在催化剂过氧化酰氯的作用下将尿液样本中的有机碘迅速消解为无机碘，无需对样本进行前处理，可节约检测时间，优化检测流程。
2Ce4++2I-→2Ce3++2I2 I2+As3+→2I-+As5+
尿样经过强氧化剂过硫酸铵的消化后，使有机碘消化成无机碘，然后在酸性环境中，利用碘对砷铈氧化还原反应的催化作用，反应中黄色的4价铈离子被还原成无色的3价铈离子，碘含量越高，反应速率越快，动态监测黄色4价铈离子被还原成无色的3价铈离子的反应速率，可得到碘含量。
本发明所述的一种尿碘定量检测试剂盒，所述试剂盒内的检测试剂由尿碘试剂R1，尿碘试剂R2和尿碘校准品组成，所述尿碘试剂R1，尿碘试剂R2和尿碘校准品的组成成分以及浓度如下：
