新生儿苯丙氨酸定量测定试剂盒的稳定性研究

摸索新生儿苯丙氨酸（Phe）定量测定试剂盒的稳定性，以建立有效的改进措施．采用破坏性试验的方法，把试剂盒以及试剂盒里的各组成部分，包括空白反应板、铜试剂、反应物A、反应物B、硫酸锌试剂和参考标准品滤纸干血片分别置于4℃冰箱（3d，7d）、37℃恒温箱（3d，7d），按照试剂盒的说明书进行操作，根据检测的准确度、精密度、灵敏度、特异性和线性的变化进行试剂盒的稳定性研究．试剂盒的各组成部分以及整个试剂盒在37℃恒温箱保存3d和7d，在4℃冰箱保存3d和7d，其测得的准确度、精密度、灵敏度、特异性和线性均保持不变．新生儿苯丙氨酸（Phe）定量测定试剂盒具有良好的稳定性．

The Study of the Stability of Neonatai Phenylanine Quantitative Diagnostic Kit

The grope for the stability of neonatai phenylalanine（Phe） quantitative diagnostic kit helps to build up valid improvement measure. By adopting destructiveness experiments, a kit and the inside of a kit of each constitute part, include blank reaction plank, copper and respond thing A and respond thing B, white vitriol and referenced standard rticle filter paper stemed a blood slice are placed in 4 ℃ refrigerators for 3 days and 7 days respectively, 37 ℃ constant temperature box for 3 days and 7 days. An operation is carried on according to the try of a kit of the manual. A research on the stability is conducted according to the examination of accurate degree, sophistication, intelligent degree, particularity and line variety. A kit of each constitutes a part and the whole are kept in 37 ℃ constant temperature box for 3 days and 7 days, and in 4 ℃ refrigerators for 3 days and 7 days, The results obtained in accurate degree, sophistication, intelligent degree, particularity and line are all constant. Neonatai phenylalanine （Phe） quantitative diagnostic kit has a good stability.
