What is a Pap test (cervical cytology)?

The Pap test (cervical cytology), sometimes called a Pap smear, is a medical test used to find changes in the cells of the cervix. The cervix is the entrance to the uterus, at the top of your vagina. This test is usually done during your routine pelvic exam.

Why is it important for me to have a regular Pap test?

The Pap test detects cervical changes that might develop into cancer over many years. These changes have no specific symptoms. The Pap test is not 100% effective in finding changes though newer versions of the test have fewer errors. Having regular tests is the way to make sure that abnormal cervical changes (cervical dysplasia) are detected early.

Who should have a Pap test?

You should have regular Pap tests beginning at the age of 25 if you are sexually active (see the new Guideline for cervical cancer screening, January 2013). Women who have ever been sexually active, including lesbians and queer women, should have the test, even if you are not sexually active right now.* 

Asymptomatic women (women without symptoms of cervical cancer) from age 25-69 who are, or have been, sexually active are recommended to have the test every three years. 

After age 70 you may stop being tested, but only after three (3) negative Pap tests in a row over a period of 10 years. But if you are 70 and over and have never had a test, then you need to have one.

You should be particularly sure to have routine Pap tests if:

  • you have already been treated for cervical abnormalities or cancer;
  • you have undergone a partial hysterectomy (removal of the uterus without removing the cervix); or if you or your mother took DES during pregnancy. DES (Diethylstilbestrol) is a drug that was given to millions of pregnant women between 1941 and 1971 to help prevent miscarriages. It was, in fact, found not to prevent miscarriage and, further, led to problems in the reproductive organs of many of the offspring of women who took the drug.

*Please note that these new recommendations do NOT apply to women who have never been sexually active, have had a full hysterectomy for a benign (i.e. non-cancerous) disease, who have had previous abnormal Pap test results, and/or have a weakened immune system. If any of these situations apply to you, ask your health care provider about when you should have a Pap test. For more information, see the new Canadian Cervical Cancer Screening Guideline FAQ Should you be screened for Cervical Cancer?

What happens during a Pap test?

A doctor or nurse practitioner does the test. If the person doing the test is a man, you may request that a woman be present as well. Throughout the test, the doctor or nurse practitioner should explain each of her actions to you. You take off your panties, and then lie on an examination table and place your feet in stirrups. If you ask to have the top part of the exam table raised up, you can see the doctor or nurse as she works. She puts on surgical gloves and then carefully inserts an instrument called a speculum into your vagina. The doctor or nurse should gently open the speculum so she can see the cervix. Ideally, the speculum should be the smallest size needed to examine your vagina and should be warm to touch.

Next she uses a small flat wooden tool, a cotton swab, or a small brush to collect cells from your cervix. A Pap test does not check for sexually transmitted infections, though sometimes a test for HPV (Human papillomarvirus) is also done at this time (this is not available in every province). She places the cell samples in a container and sends it to a laboratory where technicians (cytologists) examine the cells under a microscope.

Getting through the exam

Pap tests should not hurt but they can be unpleasant. Some women experience mild bleeding after, but this is normal and should not cause alarm. Taking long, slow breaths can help you relax the muscles inside your vagina. Tell the doctor or nurse if this is your first exam. If you are too uncomfortable at any time, ask the doctor or nurse to stop.

If you are a survivor of sexual abuse or assault you may have difficulty with the exam. You do not have to disclose that you have this history. However, if you are ready to disclose, it may be helpful for the doctor or nurse to know. For more information about what survivors can do to prepare themselves for pelvic exams please visit Getting Through Medical Examinations: A Resource for Women Survivors of Abuse and their Health Care Providers.

You can also ask a friend or relative to be with you during the exam.

What should I do to ensure that the Pap test is reliable?

To ensure that a good sample is collected:

  • Do not use vaginal douches and/or contraceptive jelly or cream 48 hours before the test;
  • Limit sexual activity 24 hours before the test by not having vaginal intercourse or Inserting anything in your vagina; and
  • Schedule your appointment for when you are mid-cycle, not during your period. Avoid scheduling an appointment while using a treatment for a yeast infection, e.g. Canesten or other yeast infection treatments.

I've had the test, what happens next?

Written test results are sent to your doctor or nurse. Most results are normal, but approximately one in ten tests will detect abnormal cells. The doctor or nurse will let you know if abnormalities are detected. She will explain the results to you and what you will need to do next.

You will not be contacted if the results are normal.

Continue to see your doctor/nurse practitioner for a Pap test every three years if you are between the ages of 25-69, and have ever been sexually active, even if the tests are normal, so that any cervical changes can be noticed.

If you are 24 or younger, the new guidelines do not recommend routine screening, even if you are sexually active.  If you are 70 or older with three (3) successive negative Pap tests, the new guidelines suggest that routine screening may stop.
