A Pap smear (also called a Pap test) is a screening test that collects a small sample of cells from the cervix — the lower part of the uterus that opens into the vagina. A laboratory examines the cells for early changes that, if left alone, could develop into cervical cancer over years. It is a screening test, not a diagnosis: an abnormal result means the cells need a closer look, not that cancer is present. The short video embedded above shows a real collection, which takes about a minute.

The test, step by step

1. Position and speculum. You lie on an exam table with your feet supported. The clinician gently places a speculum in the vagina so the cervix can be seen clearly.

2. Collecting the sample. Using a small brush and/or spatula, the clinician sweeps the surface of the cervix a few times to collect loose cells. This is the part shown in the video.

3. Preserving the cells. The sample is either spread on a glass slide or rinsed into a small container of liquid, and sent to the laboratory.

4. Done. The speculum is removed and the test is over. Any spotting afterwards is usually light and brief.

Does it hurt?

Most people describe a Pap smear as uncomfortable pressure rather than pain — a brief scraping or pinching sensation while the sample is collected. It is normal to feel nervous beforehand; telling the clinician helps, because a slower pace and a smaller speculum can make it easier.

What the results mean

A normal (negative) result means no cell changes were found, and routine screening continues on the usual schedule. An abnormal (positive) result means some cells look different. Most abnormal results are caused by HPV infection or mild changes that resolve on their own, and the usual next step is closer follow-up — a repeat test, an HPV test, or a colposcopy, where the cervix is examined under magnification. Only a small minority of abnormal results involve high-grade changes that need treatment.

Why screening matters

Cervical cancer usually develops slowly, over many years, from cell changes that a Pap smear can catch early — when they are easiest to treat. That long window is exactly why routine screening works, and why keeping to your recommended schedule matters more than any single test.

Frequently Asked Questions

How often should I have a Pap smear?

Guidelines commonly recommend screening every 3 years with a Pap test alone, or every 5 years when combined with an HPV test, for most people aged 21 to 65 — but recommendations vary by country and personal history, so follow your clinician's schedule.

Is a Pap smear the same as an HPV test?

No. A Pap smear looks at the cells themselves; an HPV test checks for the virus that causes most cervical cell changes. They are often done together from the same sample (co-testing).

What should I avoid before a Pap smear?

Many clinics suggest avoiding intercourse, douching, and vaginal medicines for about 48 hours before the test, and not scheduling it during a heavy period day, because these can affect the sample.

Can I have a Pap smear if I am pregnant?

Pap smears are commonly done during pregnancy when screening is due. Tell your clinician you are pregnant so the visit is planned accordingly.
