Human Papillomavirus (HPV) Test
A human papillomavirus (HPV) test is done to check for a high-risk HPV infection in women. HPV is a sexually transmitted infection (STI). An HPV test checks for the genetic material (DNA) of the human papillomavirus. Like a Pap test, an HPV test is done on a sample of cells collected from the cervix.
There are many types of HPV. Some types cause warts that you can see or feel. Other types do not cause any symptoms. Most people do not know they have an HPV infection.
This test will show whether a high-risk type of HPV is present. In women, high-risk types of HPV (such as types 16, 18, 31, and 45) cause changes in the cells of the cervix that can be seen as abnormal changes on a Pap test. Abnormal cervical cell changes may resolve on their own without treatment. But some untreated cervical cell changes can progress to serious abnormalities and may lead to cervical cancer over time if they are not treated.
To learn more about treatment of abnormal cervical cell changes seen on a Pap test, see the topic Abnormal Pap Test.
Although HPV is found in both men and women, this test is not used on men. The HPV test is used to detect only high-risk types of HPV. Your doctor may diagnose genital warts that are seen during a physical exam. This test is not used to diagnose genital warts caused by low-risk types of HPV.
Why It Is Done
An HPV test is done to:
The HPV test may be done at the same time as the Pap test. The results of this test can help doctors decide if further tests or treatments are needed. To learn more, see the topic Pap Test.
How To Prepare
Before an HPV test, do not douche, use tampons, or use vaginal medicines for at least 48 hours.
You will be asked to empty your bladder just before the test, both for your own comfort and to help with the exam.
Talk to your doctor about any concerns you have regarding the need for the test, its risks, how it will be done, or what the results will mean. To help you understand the importance of this test, fill out the medical test information form(What is a PDF document?).
How It Is Done
An HPV test can be done in a doctor's office or clinic by:
For this test, you need to remove your clothes below the waist and drape a paper or cloth covering around your waist. You will then lie on your back on an examination table with your feet raised and supported by stirrups. This allows your doctor to examine your vagina and genital area.
Your health professional will insert an instrument called a speculum into your vagina. The speculum gently spreads apart the vaginal walls, allowing the inside of the vagina and the cervix to be examined.
Your health professional will then use a cotton swab or a small brush to collect several samples of cells from the cervix. Cells are collected from the visible part of the cervix as well as cells from inside the opening of the cervix (endocervical canal). The samples are then placed in collection tubes and sent to a laboratory for analysis.
An HPV test can also be done on a cell sample taken during your Pap test if a technique called a liquid-based Pap test was used. For a liquid-based Pap test, cells are collected by rotating a plastic brush on the cervix. The samples are then placed in a jar of solution and sent to a lab for examination. If you have this type of Pap test and it shows abnormal cells, an HPV test may be done later on the same sample.
How It Feels
You may feel some discomfort when the speculum is inserted, especially if your vagina is irritated and tender or if it is narrow. You may also feel pulling or pressure when the sample of cervical cells is being collected.
There is very little chance of a problem from an HPV test. You may worry or feel frightened if you need more testing.
After the procedure
A human papillomavirus (HPV) test is done to check for a high-risk HPV infection in women. HPV test results are generally available in 1 to 2 weeks.
