In case of high risk HPV infection, colposcopy is clinically required. During colposcopy, if local epithelial lesions are found in the cervix, a biopsy will need to be given and the whole process from colposcopy to biopsy laboratory tests will cost about 1000 yuan in total. It is advisable to go to the hospital for this examination when you have not had intercourse for 3-7 days after menstruation. Before the examination, routine blood tests, coagulation time tests, and routine leukocyte tests should be done, and a gynecological examination should be done to exclude acute inflammation of the pelvic cavity, and the tests should be normal before the colposcopy can be done. The pathology report of the biopsy will be available in 5 working days. It is recommended to keep the vulva clean after the biopsy to avoid infection.
