If a woman has not had sex, she cannot have a TCT because the TCT brushes the surface of the cervix and cervical canal to remove some of the shed cells, and if she has not had sex, there is no way to use a vaginal dilator to open the vagina and expose the cervix. If it is done blindly, it can damage the hymen, so TCT cannot be done at this time. if you are not married but have had sex, you can have TCT, including HPV cancer screening. After the test results come out, you can judge whether there is any viral infection in the cervix and whether there is any inflammation, and you can carry out treatment according to the results of the test. However, before the test, it is necessary to pay attention to not having intercourse for 3 days and not washing the vagina, so as not to destroy some of the shed cells in the cervical canal, which will affect the results of the test.
