Cervical TCT is a screening method for cervical cancer that can also be performed at the same time when married women undergo gynecological examination, and its specific examination process is as follows: 1. The examinee empties her bladder, removes one side of her trouser leg, and lies on the examination bed in the cystotomy position; 2. The gynecologist fully exposes the cervix after propping up the vagina with a speculum, wipes out the mucus of the cervix with cotton swabs and rotates the special TCT brush for two weeks along the clockwise direction in the mouth of the cervix to get the secretion as well as the detached cells from the cervix, and then pushes the brush into the special container for timely delivery to the hospital for examination.
