What Is Cervical Cytology?

Cervical cytology smear test (EC) is a screening method for cervical cytopathy, which checks for abnormal cells under a microscope. A vaginal speculum is generally used to scrape cells from the junction of squamous epithelium and columnar epithelium of the cervix, and perform cytological examination under a microscope. The purpose of the examination is to observe the morphology of exfoliated cells and screen for vaginal and cervical infections, cervical lesions, and cervical cancer. ACOG (American College of Obstetricians and Gynecologists) recommends: "All women who have sexual activity or are over 18 years of age should undergo a cervical cytology smear every year. When three or more consecutive tests are performed, satisfactory and normal results are obtained. , The doctor can decide to reduce the number of tests for low-risk people. " In recent years, a modern cervical cytology smear technique, namely liquid-based thin-layer cytology (TCT), has become more and more widely used in cervical cytology screening. It is currently the most advanced cervical cancer in the world. Compared with the traditional Pap smear test of cervical smear, the cytology test technology significantly improves the satisfaction of the specimen and the detection rate of cervical abnormal cells. The detection rate of TCT on cervical cancer cells is close to 100%. Can find precancerous lesions, microbial infections such as mold, trichomoniasis, chlamydia, etc.
