The HPV DNA test is used to check for infection with HPV types associated with cervical cancer. Typically, the test looks for 14 different HPV types. HPV type 16 and HPV type 18 are most closely associated with cervical cancer.
How the Test Is Performed
The HPV DNA test may be done during a Pap test. If they are done together, it is called "co-testing."
You lie on a table and place your feet in footrests. Your health care provider inserts an instrument (called a speculum) into the vagina to open it slightly. This allows the provider to see the cervix. Cells are gently collected from the cervix area. The cervix is the lower part of the womb (uterus) that opens at the top of the vagina. The sample of cells is sent to a lab for examination.
How to Prepare for the Test
No special preparation is required for an HPV test. If you're getting a Pap test at the same time, it is recommended that you do not do the following in the 24 hours before the test:
- Douche (douching should never be done)
- Have intercourse
- Use tampons
For your comfort, you may want to empty your bladder just before the test.
How the Test will Feel
The exam may cause some discomfort. Some people say it feels like menstrual cramps.
You may also feel some pressure during the exam.
You may bleed a bit after the test.
Why the Test Is Performed
High-risk types of HPV can lead to cervical cancer. The HPV DNA test is done to determine if you are infected with one of these high-risk types.
Your doctor may order an HPV DNA test:
- If you have a certain type of abnormal Pap test result.
- Along with a Pap smear to screen people age 30 and older for cervical cancer.
- Instead of a Pap smear to screen people age 30 and older for cervical cancer. (Note: Some experts suggest this approach for those age 25 and older.)
The HPV DNA test results help your doctor decide if further testing or treatment is needed.
A normal result means you do not have a high-risk type of HPV. You may be asked to return in 3 or 5 years for repeat testing.
What Abnormal Results Mean
An abnormal result means you have one or more high-risk types of HPV.
If HPV types 16 or 18 are detected, your provider will recommend colposcopy. This is a procedure in which the cervix is magnified with a binocular-like instrument. Small biopsies (tissue samples) are often taken during this procedure to look for evidence of a precancerous change or cancer.
If the test is positive for one or more of the other high-risk HPV types, repeat testing in one year may be recommended. Your provider will advise you about next steps if your test is positive.
