Bleeding after cervical thin-layer liquid-based cytology and HPV screening in general cervical screening can get better in about 3~4 days. 1. Cervical thin-layer liquid-based cytology: TCT screening is a method of screening for cervical lesions by using a cell brush to remove cellular tissue from the cervical canal, which will cause a small amount of vaginal bleeding due to localized capillary rupture during the process of removal, which will gradually disappear in 3~4 days. 2. HPV (human papillomavirus) screening: it is also a way of cervical screening, also using cell brush to take the cell tissues in the cervical canal, which will also cause a small amount of vaginal bleeding after sampling, and it will disappear in 3~4 days. Women who experience a small amount of bleeding after cervical screening need not worry too much, and the bleeding will usually stop in 3-4 days. If there is persistent bleeding, it is necessary to consult a doctor.
