Do you need to check HPV for blood?

HPV infection can cause cervical intraepithelial lesions and cervical cancer. Persistent infection of high-risk HPV types is the most important factor to promote the occurrence of cervical cancer. Therefore, early detection of HPV infection, accurate typing and virus quantification are of great significance for the prevention and treatment of cervical cancer. HPV testing is gradually promoted in clinical practice as a routine screening method for cervical cancer and precancerous lesions. After removing excessive mucus from the vagina and cervix, turn it counterclockwise 3 times 1~15 cm inside the cervical os. Then put the brush into the bottom of the transfer tube, close the bottle cap, and store it at room temperature for two weeks.
