TCT is usually done by taking a specimen from the cervical canal and sending it for pathological examination. TCT is a cervical cancer prevention test that can detect abnormal cells in the cervix. Before taking the specimen, the patient empties the bladder, takes off one side of the pants and lies on the gynecological bed, takes the bladder truncated position, the doctor enters the vagina with a vaginal speculum, exposes the cervix, wipes the secretion around the cervical opening with a cotton swab, then enters the cervical opening with a TCT brush and rotates it 360 degrees in a clockwise direction for about 10 turns and puts the end of the brush into the cervical canal. The brush is then removed and placed in a bottle with fixing solution and sent to the pathology department for examination, and the results are usually available in two to three days. If both tests are normal, the examination can be done once a year regularly. If TCT and HPV are abnormal, especially with high-risk HPV infection, electronic colposcopy is recommended, and if necessary, cervical biopsy should be performed at multiple points for pathology. It should be noted that no vaginal plugs should be inserted before the examination and it is best not to have sex for 24 hours. Therefore, the TCT examination is only to take cells from the cervix and send them to pathology, there is usually no discomfort, but there will be a small amount of vaginal bleeding after the examination, which will clear up on its own after a few days, so don’t worry.
