Amplification-free fetal embryo antigen (CEA) detection method and application

The invention relates to a non-radioactive fetal embryo antigen (CEA) detection method and application, and belongs to the technical field of medical examination. The inventor puts forward that the original four times of washing are reduced to two times of washing, the step of two times of washing after the first time of incubation in the experimental intermediate process is omitted, and the original detection method is improved. The test proves that the detection process after improvement has no obvious difference from the result before improvement, and the result is stable. The method is especially suitable for scientific research of large-scale swelling label screening of hospital physical examination centers, third-party inspection institutions and the like. 本发明涉及一种免放法胎胚抗原CEA检测方法及应用，属于医学检验技术领域。本发明人提出，将原来的洗涤四次减少为洗涤两次，省略了实验中间过程的第一次温育后两次洗涤步骤，对原检测方法进行了改良。且经试验证实，改良后检测流程与改良前的结果并无明显差异，结果稳定。特别适用于医院体检中心及第三方检验机构等的大批量肿标筛查的科学研究中使用。
