lbp liquid-based cytology examination is used to carry out cytologic classification and diagnosis, it is currently a more advanced international cervical cancer cytology examination technology, compared with the traditional cervical scraping Pap smear examination significantly improves the satisfaction of the specimen and cervical abnormal cell detection rate. 1.lbp liquid-based cytology: it is to brush the cervical cell specimen in a special fixative, make a thin cell slice through LBP sedimentation technology, and interpret the report, which is used to screen and confirm the diagnosis of cervical lesions. 2. Liquid-based cytology (TCT): the specimen is obtained with a brush, placed in a special fixative, filtered through a high-precision filtration membrane, and made into a thin layer of cell slices, which can be used to screen and confirm the diagnosis of cervical epithelial neoplasia and early cervical cancer. Lbp and TCT are both cervical cytology tests, but the way the cells are processed is different.
