The following points should be avoided before the HPV and TCT tests: 1) Do not have sex before the test; 2) Do not insert vaginal pills before the test; 3) Do not douche vaginally before the test; 4) Do not do the test if the cervical area has undergone physiotherapy and is not more than two months postoperative to avoid local hemorrhage. The best time to do the TCT and HPV test is within 3-7 days after menstruation, because the cervical discharge is relatively small at this time, so that the satisfaction of the specimen taken will be normal in the clinic. You should not take a bath or have sex for one week after the test.
