If a woman is looking for a cervical biopsy to check for HPV infection, then the HPV test alone is more accurate. This is because the cervical biopsy only takes the cervical tissue in the area of the lesion, so it is not possible to test all the tissue on the cervix, so the HPV virus may not be clearly distributed in the area where the biopsy is taken, and cause no clear HPV virus infection to be examined on the biopsy, so it is possible that no pectus excavatum cells are found on the cervical biopsy, and no other abnormal problems are found, but at this point there is still HPV virus infection. Therefore, when a woman needs to be tested for HPV infection, she should not have a biopsy to confirm the diagnosis, but should have an HPVDNA or HPV karyotyping test to confirm the diagnosis. Cervical biopsy is mainly to detect the presence of cervical lesions, most commonly cervical intraepithelial neoplasia, or even cervical cancer, which must be diagnosed through biopsy, while HPV is only to detect HPV infection, not cervical lesions. So if a woman just wants to test for HPV infection, then there is usually no need for a biopsy, but a simple HPV virus test is sufficient, but if it is to check for cervical lesion problems, then a biopsy should be done.
