HPV Testing Guide
An HPV test checks for the human papillomavirus, focusing on the high-risk types linked to cervical cancer. The test is done with a sample of cells collected from the cervix, the same swab used for a Pap test, so the two are often performed together. Unlike a Pap test, which looks for abnormal cells, the HPV test looks for the virus itself, specifically the high-risk strains that can cause those abnormalities. Finding a high-risk HPV infection does not mean you have cancer, and most infections clear on their own within a couple of years. But a persistent high-risk infection raises cervical cancer risk, which is why HPV testing is a cornerstone of cervical screening for women.
What an HPV Test Checks
The HPV test looks for the DNA of high-risk human papillomavirus types, those most strongly linked to cervical cancer. It does not check for every strain, only the ones that matter most for cancer risk. Testing is limited to specific types rather than the dozens of low risk ones that cause warts.
Because high-risk HPV is found with a cervical cell sample, the test is most often performed during a pelvic exam. Results report whether a high-risk type is present, which guides the need for closer follow up.
How HPV Testing Relates to the Pap Test
The HPV test and Pap test are complementary. The Pap test looks for abnormal cervical cells, showing whether the virus has caused changes. The HPV test looks for the high-risk virus itself, showing whether the infection is present. Together they give a fuller picture of cervical cancer risk.
In modern screening, co-testing with both is common for certain age groups. Depending on your age and history, your clinician may order an HPV test alone, a Pap alone, or both at the same visit, using the same sample.
Who Should Be Tested and When
HPV testing is primarily recommended for cervical screening in women. Guidelines vary by age, with screening typically starting around age 25 and HPV testing or co-testing recommended at regular intervals through the screening years.
Your clinician follows current guidelines based on your age, risk factors, and past results. For men, there is no routine HPV test that parallels cervical screening, but HPV is linked to other cancers for which screening may be discussed.
Understanding Your Results
A negative HPV test means no high-risk virus was found, which is reassuring and supports a longer interval before the next screening. A positive result means a high-risk type is present, but it does not mean cancer, and most infections clear on their own.
If you test positive, your clinician guides next steps, which may include a Pap test if not done, more frequent monitoring, or colposcopy depending on the combination of results. Most positive findings resolve without treatment, and regular follow up is the key to prevention.
Frequently Asked Questions
What does an HPV test detect?
An HPV test detects the DNA of high-risk human papillomavirus types linked to cervical cancer. It does not check for every strain, only those that matter for cancer risk, using a cervical cell sample like the Pap test.
How is an HPV test different from a Pap test?
A Pap test looks for abnormal cervical cells, while an HPV test looks for the high-risk virus itself. They are often done together from the same sample to give a fuller picture of cervical cancer risk.
What does a positive HPV test mean?
A positive test means a high-risk HPV type is present, but it does not mean you have cancer. Most infections clear on their own. Your clinician may recommend a Pap test, closer monitoring, or further evaluation.
Who should get an HPV test?
HPV testing is part of cervical screening for women, usually starting around age 25 at intervals set by guidelines and risk. There is no routine HPV test for men, though HPV can be discussed in relation to other cancers.
