Sexual intercourse should be avoided 24 hours before the TCT examination, and after the TCT examination, if the patient has no vaginal bleeding and no abnormal symptoms, he/she can have normal sexual intercourse. TCT is an important test for screening cervical cancer. In addition to not having sex 24 hours before the test, do not douche the vagina or use vaginal suppositories within 24-48 hours before the TCT test, and do not have an internal vaginal examination. If you have vaginal inflammation, it is recommended to treat the inflammation before performing the TCT test. The test needs to be performed during the non-menstrual period. The TCT test uses a specialized sampler to collect a sample of cervical cells during the test, which may cause a small amount of bleeding after the test. If there is a small amount of vaginal bleeding, it is not recommended to have sex, which may lead to wound infection. If there is no vaginal bleeding or the bleeding stops, you can have sex. If there is abnormal heavy vaginal bleeding, go to the hospital in time.
