The TCT test is fine, and an HPV test is also needed. TCT, also known as Thin Layer Liquid-based Cytology, is a primary screening test for cervical cancer, while HPV, also known as Human Papilloma Virus, is a test to determine whether or not you are infected with HPV. There is a slight difference between the two types of tests and their purposes, but the results of these two tests can be used to determine whether or not you have cervical cancer or precancerous lesions as early as possible. If TCT alone is performed and no problems are detected, it does not necessarily mean that there is no abnormality. To be on the safe side, it is still necessary to have an HPV test because HPV infection is one of the high-risk factors for cervical cancer. It is important to note that you should avoid sexual intercourse within 24 hours before having the test, as well as vaginal douching or the use of vaginal suppositories, and avoid having the test during menstruation. If the test results are abnormal, it is recommended to actively cooperate with the doctor for treatment.
