Human Papillomavirus (HPV) E6/E7 Antigen in Cervical Cell Scrapings
This test measures the presence of specific viral proteins (E6/E7) from certain types of human papillomavirus (HPV) found in cervical cells. It helps assess whether HPV infection may be contributing to precancerous changes.

Why This Test Is Done
Your healthcare provider may recommend this test if you have symptoms like abnormal vaginal bleeding, persistent genital warts, or if you’re at higher risk for HPV-related conditions (e.g., due to a weakened immune system or history of HPV exposure). It’s also sometimes used as part of cervical cancer screening when other tests are inconclusive.
How the Test Works
A sample of cervical cells is collected (usually via a swab) and tested for the E6/E7 proteins, which are markers of high-risk HPV types linked to precancerous changes. The test detects these proteins through a specialized immunoassay method.
Sample Collection and Preparation
The test uses cells scraped from your cervix. This is a quick, painless procedure often done during a Pap test or colposcopy. The sample is then processed in a lab to identify the viral proteins.
What to Expect Before the Test
No special preparation is needed, but avoid sexual activity, douching, or using vaginal medications 24–48 hours before the test. If you’re pregnant or have a history of heavy bleeding, let your provider know.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Positive results indicate the presence of HPV E6/E7 proteins, which may signal an active infection by certain high-risk HPV types. While not all infections lead to cancer, persistent infection can increase the risk of precancerous lesions or cervical cancer. This test helps guide further monitoring or treatment options, such as follow-up exams or targeted therapies.
