Human papillomavirus (HPV) antigens are pivotal in the diagnosis and prevention of cervical cancer. HPV antigens are proteins expressed by the virus that can be detected in cervical cells. Testing for these antigens can help in early identification of precancerous changes in the cervix. HPV vaccines, which contain inactivated or recombinant HPV antigens, stimulate the immune system to produce antibodies that protect against future HPV infections.
