Why Is This Test Done?

Your healthcare provider may recommend a Pap test to screen for cervical cancer, monitor changes in your cervix after treatments, or check for signs of sexually transmitted infections (STIs) or other vaginal issues. It’s also part of routine health check-ups for women of certain ages.

What Happens During the Test?

A healthcare professional gently collects cells from your cervix using a small brush or spatula. The sample is then placed on a slide and prepared for microscopic examination. You may feel slight discomfort, but it usually takes only a few minutes.

What to Expect After the Test

You can return to your normal activities immediately after the test. There may be mild spotting or light bleeding for a day or two, but this is normal. Avoid douching or sexual activity for 24 hours afterward to allow the cells to heal properly.

What Does the Test Result Mean?

Results are interpreted by a pathologist and may indicate normal cells, inflammation, infection, or abnormalities that could require further testing or follow-up. Your provider will discuss the results with you and explain next steps if needed.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How often should I get a Pap test?
The frequency depends on your age, medical history, and overall health. Typically, women aged 21–65 are recommended to get a Pap test every 3 years if results are normal. If you have a higher risk (e.g., HIV, history of HPV, or prior abnormal results), your provider may recommend more frequent testing.
What if my Pap test shows abnormal cells?
Abnormal results don’t always mean cancer, but they may indicate changes that need further evaluation. Your provider could recommend additional tests, such as HPV testing or a colposcopy, to investigate further. Early detection increases the chances of successful treatment.
Can I prepare for a Pap test?
No special preparation is needed, but avoid using vaginal medications, douches, or sexual activity 24 hours before the test. If you’re on your period, schedule the test for a day when your cycle is stable to get the most accurate results.
