What might abnormal Pap smear results indicate in a female patient?

Abnormal Pap smear results primarily indicate a potential presence of precancerous changes or cervical cancer, often linked to infection with the Human Papillomavirus (HPV). HPV is a sexually transmitted virus that has several strains, some of which are high-risk types associated with the development of cervical dysplasia and cancer. When a Pap smear shows abnormal cells, healthcare providers often test for HPV to determine if a high-risk strain is present, as this significantly influences the management and treatment options for the patient.

Other infections listed, such as Chlamydia trachomatis, Candida albicans, and Trichomonas vaginalis, can cause various gynecologic issues and may present with symptoms or changes in vaginal discharge but are not typically the direct cause of abnormal results on a Pap smear. The Pap test is specifically designed to detect changes in cervical cells, which are primarily associated with HPV-related lesions.
