HPV Testing: A Practical Guide to Screening and Results
Human papillomavirus (HPV) is a common sexually transmitted infection with many types, some of which are linked to cervical and other cancers. HPV testing looks for genetic material from high-risk HPV types in cells collected from the body, most often the cervix. This guide explains what the test detects, when screening is recommended, and how to interpret results.
Key takeaways
- HPV testing detects the virus itself, while a Pap test looks for abnormal cells that HPV can cause.
- Screening recommendations depend on age, prior test results, and whether you have a cervix.
- A positive high-risk HPV result does not mean you have cancer; most infections clear on their own.
- Some HPV tests can be done on a sample you collect yourself, depending on current guidance and availability.
- Talk with a clinician about which screening approach and interval is right for you.
What HPV Testing Detects
HPV testing identifies the presence of genetic material from high-risk HPV types in a sample of cells. These types are called high-risk because persistent infection with them is associated with cervical cancer and several other cancers. The test does not detect every HPV type, and it does not tell you how long you have had the infection.
Most HPV tests are run on a cervical sample collected during a pelvic exam, similar to the sample used for a Pap test. Some tests can also be performed on a self-collected vaginal sample when a clinician or program offers that option. Results are typically reported as positive or negative for high-risk HPV, and some tests specify whether HPV 16 or HPV 18, the two highest-risk types, are present.
Who Should Get Screened
Cervical cancer screening recommendations are based on age and risk factors. In general, screening begins at age 21 or 25, depending on the guidance you follow, and continues until around age 65 for people at average risk. Screening may include an HPV test alone, a Pap test alone, or both tests together, often called co-testing.
People who have been vaccinated against HPV still need routine screening, because the vaccine does not cover all high-risk types. If you have had abnormal screening results, a weakened immune system, or a history of cervical precancer, your clinician may recommend a different schedule. Screening is not routinely recommended for people who have had a total hysterectomy for a non-cancer reason, but individual circumstances vary.
How to Interpret Results
A negative HPV test means high-risk HPV was not detected in the sample. Depending on your age and screening history, your clinician may recommend waiting several years before the next test. A positive result means high-risk HPV was found, but it does not mean you have cancer. Many HPV infections clear without treatment, especially in younger people.
If your result is positive, the next step depends on which test was done and whether you also had a Pap test. Your clinician may recommend repeat testing sooner, a colposcopy to examine the cervix more closely, or a biopsy. A positive result for HPV 16 or 18 often leads to closer follow-up because these types carry a higher risk. Ask your clinician to explain what your specific result means for your next steps.
HPV Testing vs. Pap Testing
HPV testing and Pap testing are different tools that are often used together. A Pap test examines cells under a microscope to look for changes that could become cancer. An HPV test looks for the virus that can cause those cell changes. Because HPV testing can detect risk earlier, some guidelines now use it as the primary screening method.
Neither test diagnoses cancer on its own. If either test is abnormal, additional evaluation may be needed. Co-testing combines both methods and can be recommended for certain age groups. The right choice depends on your age, health history, and the guidelines your clinician follows, so discuss the options rather than assuming one test is always better.
Frequently Asked Questions
is hpv a std
Yes. HPV is a sexually transmitted infection. It spreads through skin-to-skin contact during vaginal, anal, or oral sex, and it is the most common sexually transmitted infection in the United States. Many people with HPV have no symptoms and do not know they have it.
is hpv an std
Yes, HPV is classified as a sexually transmitted infection. It can be transmitted through intimate skin-to-skin contact, including contact that does not involve penetration. Condoms reduce but do not fully eliminate the risk of transmission because HPV can be present on skin not covered by a condom.
Can HPV go away on its own?
Most HPV infections are cleared by the body's immune system within one to two years without treatment. However, some infections persist, and persistent infection with high-risk HPV types is what can lead to cell changes and, over many years, cancer. Regular screening helps detect persistent infections and any cell changes early.
Do I need HPV testing if I had the HPV vaccine?
Yes. The HPV vaccine protects against the types most commonly linked to cancer, but it does not cover every high-risk type. People who have been vaccinated should still follow the cervical cancer screening schedule recommended for their age and situation.
