TCT test is short for liquid-based thin-layer cell testing, a screening test for HPV that is very necessary. TCT is a cervical cancer cytology screening technique that uses a liquid-based thin-layer cell testing system to detect cervical cells and perform cytologic classification for diagnosis. It can significantly improve the satisfaction of the specimen and the detection rate of abnormal cervical cells. It can also detect some pre-cancerous lesions, microbial infections and so on. Currently, screening for high-risk HPV virus is mainly through TCT and HPV testing. These two tests are the main means of preventing early cervical cancer lesions, and women are recommended to be screened as early as possible. Once high-risk HPV virus infection occurs, it is important to treat it promptly and follow the doctor’s instructions for medication to strive for early recovery. Precautions before having TCT and HPV tests are as follows: 1. Avoid sexual intercourse within 24 hours before the test so as not to affect the test results. 2. Do not douche the vagina or use vaginal suppositories within 48 hours, and do not do endoscopy. 3. If there is inflammation, it is recommended not to check and treat the inflammation first so as not to affect the diagnostic results. 4. It is best to take the test during the non-menstrual period. Once you have been detected with high-risk HPV infection, in addition to actively cooperating with the doctor’s treatment, you must pay attention to personal hygiene, eliminate unclean sex, maintain a regular routine, and improve immunity.
