The TCT and HPV tests require brushing of the basal cells of the cervical canal, so there are certain time requirements, for example, no intercourse for 3 days before the test, no vaginal medication for 3 days, and no vaginal douching for 3 days, otherwise the normal cellular tissue of the vagina, including the cervix, will be damaged and the results of the tests may be affected. After the results of TCT and HPV are available, treatment can be administered according to the situation. If there is no major problem, TCT and HPV can be checked at intervals of one year, but annual checkups are necessary to ensure that there is no viral infection.
