What is a Pap test?
The Pap test is a simple, quick, and painless gynecological examination that is the most reliable way to prevent cervical cancer. The Pap test was developed in 1928 by the distinguished Greek physician George Papanicolaou, who began his research as early as 1923—hence its name.
During the exam, the gynecologist takes a small sample of cells from the cervix, which is sent to a specialized laboratory for analysis.
Results are usually available within a few days, and the procedure takes less than 5 minutes.
What does a Pap test show?
The Pap test detects any changes or abnormalities in the cells of the cervix that, if not treated promptly, can develop into cancer.
It is worth noting that cervical cancer is the fourth most common form of cancer in women, and the Pap test, combined with regular preventive screening, can reduce deaths from it by 80%.
The most common findings that may be detected are:
- Cervicitis / vaginitis
- Atypical squamous cells of undetermined significance
- Low- or high-grade dysplasia
- Cancerous cells
In some cases, the test may also detect infections such as chlamydia, candidiasis, ureaplasma, mycoplasma, or herpes. However, it is not a test specifically for infections, as the absence of detection does not confirm that they are not present.
Important: The Pap test does not directly detect the HPV virus, but rather the cellular changes it may cause. A separate HPV test is required to detect the virus itself.
When & How often is it done?
It is recommended that the Pap test be performed annually as part of a routine preventive gynecological exam. However, if symptoms such as pain, bleeding, or unusual discharge occur, it is important to contact your gynecologist immediately.
Who should get tested:
- Women who are sexually active
- Women between the ages of 24 and 64—in younger women, lesions often resolve on their own
- Women with a gynecological history who have not undergone a hysterectomy
Special cases:
- First test: Recommended approximately 1 year after first sexual intercourse, as the HPV virus takes time to cause lesions
After childbirth: Provided there were no complications, the test is performed at least 3 months after delivery.
Types of exams
There are two ways to perform a Pap test:
Conventional Pap Test
The cell sample is placed directly on a microscope slide and analyzed in the laboratory. This is the classic method that has been used for decades.
Liquid-Based Pap Test (ThinPrep / BestPrep)
The sample is transferred to a laboratory tube containing a special liquid and analyzed using staining techniques. This method offers significant advantages:
- All collected cells are utilized
- It allows for multiple analyses to be performed on the same sample without the need for re-sampling
- It is considered more reliable than the conventional method
- It allows for simultaneous HPV testing when necessary
In our clinic, we use both methods as appropriate
Pap Test Results
Pap test results are usually available within a week of the test, at which point your doctor will contact you.
The results may show normal cells, various degrees of dysplasia, or evidence of HPV. Below we explain what each means:
Common Pap Test Results:
- Negative (Normal): No abnormal cells were detected. No further action is required until the next annual screening.
- Atypical cells of undetermined significance (ASCUS): Minor changes often associated with inflammation or the HPV virus. A follow-up test is usually required.
- Mild dysplasia (LSIL): Low-grade changes, often the result of an HPV infection. In many cases, they resolve on their own.
- Moderate or severe dysplasia (HSIL): High-grade changes that require further investigation and immediate follow-up.
- Carcinoma / Positive: Detection of cells that require immediate medical evaluation and treatment.
Remember: An abnormal result does not necessarily mean that cancer is present. In most cases, lesions can be effectively treated, especially when detected early.
How to Prepare for a Pap Test
To ensure the most reliable result, it is recommended to avoid sexual intercourse for at least 24 hours before the test, as well as vaginal douches or the use of vaginal creams and suppositories for the previous 2–3 days.
The test should not be performed during menstruation, as the presence of blood may affect the evaluation of the sample.
Also, if there is a suspected or confirmed infection, inform your doctor, as the test may need to be postponed.
Frequently Asked Questions (FAQ)
Category 1 indicates a normal result—no abnormal cells were detected. No further action is required beyond the regular annual screening.
Cervicitis is an inflammation of the cervix and is one of the most common findings. The presence of vaginal bacteria indicates a disturbance in the normal vaginal flora. Both conditions are treatable with appropriate therapy and are not necessarily associated with serious pathology.
The Pap test does not directly detect the HPV virus, but rather the cellular changes it may cause. If there is a suspicion, the gynecologist will recommend an HPV test, specifically using the PCR method, which can precisely identify the strain of the virus responsible for the infection.
Atypical squamous cells of undetermined significance (ASCUS) are one of the most common reasons for an abnormal test result. In most cases, they are associated with mild inflammation or HPV and are not a sign of cancer. Your doctor will determine whether a follow-up test or colposcopy is necessary.
Yes, that’s perfectly normal. Light spotting immediately after the exam is common and usually goes away quickly. However, if the bleeding is heavy or prolonged, contact your doctor.
The test is generally painless. You may feel slight pressure or momentary discomfort during the sample collection, which subsides immediately. If you feel anxious or tense, let your doctor know—relaxing your muscles significantly helps with comfort during the exam.
