凝聚胺法放射免疫快速测定癌胚抗原的应用

Application of polybrene in rapid radioimmunoassay carcinoembryonic antigen

摘要: 目的探讨凝聚胺在放射免疫测定癌胚抗原(CEA)中的应用。方法 26例血清标本分别用凝聚胺法和常规法相比较。结果凝聚胺法与常规法比较测定结果无显著差异。该方法的检测限为2 μg/L,线性范围0-80 μg/L,变异系数3.78%,回收率在96.65%-101.31%之间。结论凝聚胺法简单、快速,可以用于临床常规检测。

Abstract: Objective Explore the value of polybrene in carcinoembry, onic antigen (CEA) of radioimmunoassay. Methods 26 samples of serum were detection by polyrene and compared with normal test. Results There was not differences between the normal test and ploybrene test. The sensitivity of the assay was 2 μg/L.The linear range was from 0 to 80 μg/L The precision was 3.78 μg/L. The analytical recovery rate was from 96.65% to 101.31%. Conclusion The ploybrene test is simple, rapid and it can be used for normal test in clinic.
