Cervical cytology test is a simple, economical and non-invasive classical screening technique for cervical cancer and precancerous cervical lesions, which is performed by a clinician-like, pathologist under a microscope to interpret the cell morphology on specially processed cervical cytology films to understand the presence of abnormal epithelial cells. Currently, there are two types of cervical cytology tests: 1) traditional cervical cytology smear (also known as cervical scraping and Pap smear), which is gradually replaced by liquid-based cytology because of its low positive rate due to many factors; 2) cervical liquid-based cytology test (LBC, TCT), which is mostly used in clinical practice because of its advanced membrane collection, ultra-thin film production and computer-assisted film reading. Currently, this method is mostly used in clinical practice, and the cost is slightly higher compared to the former. Traditional cervical cytology smear report Traditional cervical cytology, commonly known as cervical smear, is usually classified according to the 5 levels of Pap smear, i.e., from I to V. Usually, Pap smear I is considered normal and recommended to be reviewed after 1 year; Pap smear lla is considered normal or inflammatory and recommended to be reviewed in 3-6 months; Pap smear llb and above are recommended for further cervical HPV testing and colposcopy to clarify or exclude cervical The cervical HPV test and colposcopy are recommended to clarify or exclude cervical pathology. Cervical fluid-based cytology report Cervical fluid-based cytology uses a special membrane filming technique to filter out some blood cells and impurities, and can be read by computer to quickly find suspicious abnormal epithelial cells, which is more accurate than traditional scraping; at the same time, the report adopts TBS grading diagnostic criteria, which is more intuitive and assesses the satisfaction of the type and amount of similar cells: 1, NILM: no abnormal epithelial cells seen epithelial cells, equivalent to Pap grade I; 2, ASCUS: atypical squamous epithelial cells; 3, LSL: low-grade squamous intraepithelial neoplasia; 4, HSlL: high-grade squamous intraepithelial neoplasia; 5, ASC-H: atypical squamous epithelial cells, not excluding high grade lesions; 6, AGC: atypical glandular epithelial cells. Cytologic abnormalities in cases 2 to 6 need to be clarified or excluded by further colposcopy, etc. Cervical cancer and precancerous lesions. The sensitivity and specificity of the results are limited due to factors such as sampling, production and bias of the interpreters, i.e., the absence of abnormal cells or normal range in the reported results does not necessarily mean that the cervical cervix is normal or free of lesions. Biopsy, etc.
