本文对国产及进口CHE试剂进行评价,两种试剂的组成及不同温度下的稳定性相同,精密度良好(CV均<5%),相关系数为0.9826~1.054.国产试剂吸收峰为410nm,线性16500u/L,回收率97.5%~101.1%,平均98.6%,正常参考范围6634±±2956u/L,进口试剂吸收峰为405nm,线性14500u/L,回收率99.00%~102.3%,平均100.3%,正常参考范围66.79±3092u/L,结果表明,国产CHE试剂完全可以替代进口CHE试剂。
In this paper, the domestic and imported CHE reagents were evaluated. The composition of the two reagents and the stability at different temperatures were the same with good precision (CV <5%) and the correlation coefficient was 0.9826 ~ 1.054. The absorbency peak of domestic reagent is 410nm, the linearity is 16500u / L, the recovery rate is 97.5% -101.1%, the average is 98.6%. The normal reference range is 6634 ± 2956u / L, the recoveries ranged from 99.00% to 102.3% with an average of 100.3%. The normal reference range was 66.79 ± 3092u / L. The results showed that domestic CHE reagent could replace imported CHE reagent completely.
