A Pap smear is a quick office procedure where a clinician collects a small sample of cells from your cervix and sends them to a lab to check for abnormalities. The entire process typically takes less than five minutes, though the actual cell collection lasts only seconds. Here’s what happens from start to finish.
How to Prepare Beforehand
For the most accurate results, avoid intercourse, douching, and any vaginal medicines, spermicidal foams, creams, or jellies for two days before your appointment. These can wash away or obscure the cells the lab needs to examine. Try not to schedule the test during your menstrual period. It can technically be done while you’re menstruating, but it’s easier to get a clean sample when you’re not. If you’re experiencing bleeding outside your regular period, though, don’t delay your test.
What Happens During the Exam
You’ll change into a gown and lie back on the exam table with your feet in stirrups. Your clinician will ask you to slide forward so your hips are at the very edge of the table, which gives them a better angle to see your cervix.
The first step is inserting a speculum, a smooth plastic or metal instrument that gently holds the vaginal walls apart so the cervix is visible. Most providers start with the smallest size and warm it with tap water first. They’ll separate the labia with one hand, then slowly guide the speculum in with a slight downward angle. Once it’s in place, they’ll open it gradually until the cervix comes into full view. You’ll feel pressure and stretching at this point, which can be uncomfortable but is rarely painful.
Next comes the cell collection, which is the fastest part. Using a small spatula, the clinician places one end at the opening of the cervix and rotates it in a full circle to gently sweep cells from the outer surface. Then a tiny brush, about the diameter of a pencil, goes just inside the cervical opening and is rotated half a turn to gather cells from the inner canal. Some providers use a single broom-shaped device that collects both samples at once. You may feel a brief scraping or light cramping sensation during this step, but it passes in seconds.
The collected cells are either swished into a small vial of liquid (the more common method today) or spread directly onto a glass slide and treated with a fixative to preserve them. The speculum is then closed and removed, and the exam is over.
What It Actually Feels Like
Most people describe the speculum as the most noticeable part, a sensation of pressure or fullness rather than sharp pain. The cell collection itself feels like a quick scrape or pinch. Relaxing your pelvic muscles and taking slow breaths genuinely helps because tension makes the vaginal walls grip the speculum more tightly, which increases discomfort.
If you’re anxious, it’s worth telling your provider before they start. Knowing what to expect at each step reduces both anxiety and the perception of pain. Some clinicians will walk you through every movement as it happens, which many patients find reassuring. If you’ve had painful experiences in the past, ask about using a smaller speculum or extra lubricant.
After the Test
You can get dressed and go about your day immediately. Light spotting is common and normal but should stop within 24 hours. You shouldn’t feel cramping or lingering pain. If bleeding continues past a day or you experience discomfort lasting more than a few minutes, let your provider know.
Results typically come back within one to three weeks. The lab classifies what it finds using a standardized system, and results generally fall into a few categories.
Understanding Your Results
A normal (negative) result means no concerning cell changes were found. This is the most common outcome.
An unsatisfactory result means the lab couldn’t read the sample properly, often because there weren’t enough cells or something obscured them. You’ll simply need to repeat the test.
Abnormal results have different levels of severity:
- ASC-US (atypical squamous cells of undetermined significance) means some cells look slightly unusual but aren’t clearly abnormal. This is the mildest finding and is often caused by an HPV infection, inflammation, or even low estrogen levels. Your provider may order an HPV test or ask you to come back in a year.
- LSIL (low-grade squamous intraepithelial lesion) indicates mild cell changes, typically linked to an HPV infection. Many of these resolve on their own, but your provider will recommend follow-up testing to make sure.
- HSIL (high-grade squamous intraepithelial lesion) means more significant cell changes that could develop into cancer if left untreated. This usually leads to a colposcopy, a closer examination of the cervix, and possibly a biopsy.
An abnormal Pap result does not mean you have cancer. It means cells need closer monitoring or further evaluation.
Pap Smear vs. HPV Test
The collection process is virtually identical for both tests. The same speculum, the same brush or spatula, the same cervical swab. The difference is what the lab does with the sample. A Pap smear examines cells under a microscope to look for physical changes. An HPV test checks the same sample for the presence of high-risk strains of human papillomavirus, the virus responsible for nearly all cervical cancers. When both tests are done together (called co-testing), cells from a single collection can often be used for both.
How Often You Need One
Current guidelines from the U.S. Preventive Services Task Force recommend the following schedule for people at average risk:
- Ages 21 to 29: Pap smear every 3 years. HPV testing alone is not recommended in this age group.
- Ages 30 to 65: Three options, all equally acceptable. A Pap smear every 3 years, an HPV test alone every 5 years, or both tests together every 5 years.
- Under 21: No screening recommended, regardless of sexual activity.
- Over 65: Screening can stop if you’ve had adequate prior results, defined as three consecutive normal Pap results or two consecutive negative HPV results within the past 10 years, with the most recent test within the last 5 years.
- After a hysterectomy: If your cervix was removed and you have no history of high-grade precancerous cells or cervical cancer, screening is no longer needed.
People with HIV, a compromised immune system, or a history of high-grade precancerous lesions may need more frequent screening on an individualized schedule.
