摘要
目的 :为了解 CA- 12 5、CEA、唾液酸 (SA)三种肿瘤标记物对妇科肿瘤的诊断的各自的和联合检测的敏感性。方法 :CA- 12 5用酶免疫法 (EL ISA) ,CEA用放射免疫法 (RIA) ,SA用化学比色法。结果 CA- 12 5敏感性为 83.6 % ,CEA为5 5 .7% ,SA为 70 .2 % ,三项联合敏感性达 98%。结论 :单种标记物无论敏感性还是特异性的诊断均受到限制 ,如采用联合几种检测则可提高敏感性和特异性 。
Objective:To investigate the sensitivities of each single test of the tumour symbols CA 125,CEA,SA and multi associated tests in the diagnosis of gynaecololgic tumour Methods:CA 125 were detected by enzyme immunoassary;CEA were detected by RIA;SA were detected by chemical colorimetric analysis Results:The sencitivities of CA 125,CEA,SA were 83 6%,55 7%,70 2% respectively and the sensitivities of multi associated tests were 98% Conclusion:Both sensitivity and specificity of each single symbol in diagnoses are restricted If the multi associated tests are used,not only the sensitivity and specificity but also the diagnostic levels of the early stage of tumour can be raised effectively
