摘要
目的优选出粪便隐血试剂的稳定性最佳配方。方法采用正交试验方法,观察试剂组分四甲基联苯胺、过氧化脲、维生素C和聚乙烯吡咯烷酮在4℃条件下对粪便隐血试剂的稳定性影响。结果上述4种物质组分浓度分别为5、2、1及1g/L时,粪便隐血试剂的稳定性最好。结论通过正交法确定的最优配方可使试剂稳定性达180d。
Objective Optimization the prescription for the stabiblity of FOB kit. Method The kit such the single conposition as tctramethyl benzidine,urea peroxide, VitC, polyvinyl pyrrolidone to optimize the stability by orthogonal experiment at 4 ℃. Results Based on the experiment, we follow the consequence which the concentration respectively 5, 2, 1, 1 g/L is the best. Conclusion The stability of kit is up to 180 days by the optimal prescription.
