National guidelines provide for HPV testing in patients with certain abnormal Pap smears and in other select clinical indications. The presence of high-risk HPV leads to more frequent examination or more aggressive investigation (e.g., colposcopy and biopsy). There is no medical indication for low-risk HPV testing (HPV types that cause genital warts or very minor cell changes on the cervix) because the infection is not associated with disease progression and there is no treatment or therapy change indicated when low-risk HPV is identified.
