摘要:

目的 评价以丙三醇为稳定剂配制的精浆生化检测质控品的性能,以确定更优质量的精浆生化检测质控品配制方法。方法 分别检测用丙三醇为稳定剂配制的精浆生化检测质控品(A组)和精浆原液生化检测质控品(B组)中精浆果糖和精浆中性α-葡萄糖苷酶水平,参照相关指南对其进行均匀性和稳定性评价。对2种质控品进行日常质控检测,比较2种质控品的检测精密度。结果 A组和B组质控品精浆果糖和精浆中性α-葡萄糖苷酶F值均<F临界值[F0.05(9,10)=3.02],均匀性较好。A组精浆果糖项目配制29 d内t<t临界值[t0.05(5)=2.57],稳定性较好;B组精浆果糖项目第8天t>2.57,稳定性低于A组。A组精浆中性α-葡萄糖苷酶项目配制85 d内t<2.57,稳定性较好。B组中性α-葡萄糖苷酶项目配制29 d内t<2.57,稳定性低于A组。日常质控结果显示,A组和B组均有超过95%检测结果在±2s范围内,符合正态分布,A组和B组2个项目的质控数据变异系数(CV)均<10%。结论 2种质控品的均一性均较好,日常质控检测结果均可满足要求。以丙三醇为稳定剂的精浆生化检测质控品较精浆原液稳定性更高。

Abstract:

Objective To evaluate the performance of seminal plasma biochemical quality control products prepared with glycerol as stabilizer,in order to determine a high quality seminal plasma biochemical quality control product preparation method. Methods Group A used glycerol as stabilizer to prepare seminal plasma biochemical quality control products,and group B used seminal plasma biochemical quality control products directly into seminal plasma. The 2 groups were determined for fructose and neutral alpha-glucosidase,and the homogeneity and stability were evaluated. Daily quality control test and analysis were performed to compare the precisions of the 2 biochemical quality control products. The 2 biochemical quality control products were determined daily,and the precisions of the 2 methods were compared. Results In the homogeneity evaluation test,the F values of seminal plasma fructose and neutral alpha-glucosidase of the 2 groups were <Fcritical value [F0.05(9,10)=3.02]. The homogeneity was good. In the stability evaluation test,the fructose of group A had t<tcritical value [t0.05(5)=2.57] within 29 d after preparation,and the stability was good. The fructose of group B had t>2.57 at the 8th day. The stability was lower than that of group A. The neutral alpha-glucosidase of group A had t<2.57 within 85 d,and the stability was good. The neutral alpha-glucosidase of group B had t<2.57 within 29 d after preparation. The stability was lower than that of group A. The daily quality control results showed that the seminal plasma biochemical quality control results of the 2 groups(above 95%) were distributed within ±2s,and the coefficient of variation(CV) of the quality control data of the 2 items between the 2 groups was <10%. Conclusions The seminal plasma biochemical quality control product formulated with glycerol as stabilizer is more stable than seminal plasma stock solution,and it can be used as a stabilizer of seminal plasma biochemical quality control product.
