Abnormal Pap Test

You may have a Reference Pap test as part of your routine gynecologic exam. A Pap test is used to identify abnormal cell changes on your Reference cervix Opens New Window Reference Opens New Window and to screen for Reference cervical cancer Opens New Window. Pap test screening is the most effective way to detect early abnormal cervical cell changes.

Women older than age 30 may have a screening test for HPV infection at the same time they have their Pap test.^{Reference 1}

Pap test screening schedule

The recommended Reference Pap test schedule is based on your age and on things that increase your risk. For most women, it is best to have a Pap test every 1 to 3 years. Talk to your doctor about when to have your first Pap test and how often to have this test.

Abnormal Pap test result

If your Pap test result is abnormal, the lab will use Reference the Bethesda system (TBS) to describe how severe the problem is. Your doctor will use these results to decide how to treat the problem.

Following an abnormal Pap test result, more tests may be needed to determine whether an infection is present or to determine the severity of cervical cell changes. These additional tests include:

• Reference Human papillomavirus (HPV) DNA test. HPV testing is done to identify high-risk types of HPV infection. If your abnormal Pap test is caused by HPV, knowing whether you have a high-risk type of HPV can help guide your evaluation and treatment decisions.
• Reference Colposcopy and cervical biopsy. A colposcopy uses a magnifying instrument called a Reference colposcope Opens New Window Reference Opens New Window to look at the vagina and the cervix. Cell abnormalities (Reference dysplasia Opens New Window) that might be missed by the naked eye can be seen with the colposcope. A cervical biopsy removes a small piece of the cervix so the tissue can be examined under a microscope.
• Reference Cone biopsy. This is an extensive form of a cervical biopsy. It is called a cone biopsy because a cone-shaped wedge of tissue is removed from the cervix and examined under a microscope. A cone biopsy may also serve as treatment by removing the abnormal cervical cells.

What to think about

Testing methods, such as Reference liquid-based collection, are being used in many areas of the United States. Liquid-based collection methods allow testing for HPV at the same time as a Pap test, but these methods may not be available everywhere and may be more costly.

The terms used to report Pap test results vary depending on which classification system is used. The Bethesda system (TBS) is used by most labs in North America. Other classification systems are used around the world.

• Reference The Bethesda system (TBS) classifies cervical cell changes by type of abnormality, such as Reference atypical squamous cells (ASC) Opens New Window.
• Older classification systems use the term Reference dysplasia Opens New Window to describe cervical cell changes or describe the changes as mild, moderate, or severe.
