Pap smear, HPV test and co-test: what each one looks for

A Pap smear, also called a Pap test or cervical cytology, collects cells from the surface of the cervix and checks them under a microscope for changes that could turn into cancer over time. It can also pick up infection or inflammation that is not cancer.

An HPV test checks the same kind of sample for high-risk types of human papillomavirus, the virus that causes almost all cervical cancer. It does not look at the cells themselves. It tells you whether the virus that drives cell changes is present.

A co-test runs both tests on one sample taken at one visit. In the United States, ACOG advises a Pap test every 3 years for women aged 21 to 29. For women aged 30 to 65, ACOG lists three options: an HPV test alone every 5 years, a co-test every 5 years, or a Pap test alone every 3 years. The UK and Australia use HPV testing as the first screen, which is why readers from those countries may be used to a 5-year interval. Korea's national program uses a different schedule, described below. Neither approach is wrong; they reflect different health systems. If you are unsure which test you are due for, bring your last result and ask at the consultation.

In Korean the test is usually called jagung-gyeongbu-am geomsa, which means cervical cancer screening. The word Pap, said the English way, is also understood at most clinics.

Korea's national cervical screening program

Korea runs a National Cancer Screening Program for six cancers. For cervical cancer, the program offers women aged 20 and over a Pap smear every 2 years. The 20-and-over rule has applied since 2016; before that the program started at age 30. There is no out-of-pocket cost for the national screen itself. The screening is done at designated medical institutions, and you show your National Health Insurance certificate or card when you arrive. The institution notifies you of the result within 15 days of the test.

If you are a foreign resident enrolled in NHIS, you are inside this system. The program runs on a two-year cycle, and NHIS sends a screening notice to eligible women every two years, by mail to the address on your residence registration or electronically if you have signed up for that. In a given year you may or may not be due. Ask the clinic to check your eligibility when you book, or check with NHIS directly.

The national program covers a Pap smear only. An HPV test is not part of the program, so if you want HPV testing or a co-test, that part is paid separately even when the Pap smear itself is covered.

Not every clinic is a designated screening institution. Before you book anywhere for the national screen, ask whether the clinic is designated for cervical cancer screening. If it is not, you can still have the test there, but it is billed as a private test rather than through the program.

Pap smear price in Korea without NHIS: paying yourself

If you are visiting Korea, on a visa that does not include NHIS, or simply not eligible this year under the two-year cycle, you pay for the test yourself. In Korea this is called a non-covered or self-pay item. Each clinic sets its own fee for self-pay tests, which is why prices you see quoted online for a Pap smear in Korea vary.

When you ask for a price, make sure you know what it includes. A Pap smear alone, an HPV test alone, and a co-test are three different line items. A consultation fee may be separate. A pelvic ultrasound is a separate test and is not part of cervical screening. If you want a written result in English, ask whether that is included or charged.

Fees for any test are stated at the consultation and in the written plan. Medical records and receipts are issued in English on request, and the clinic prepares the documents international insurers typically require, including an itemized English receipt. Whether a test is reimbursed depends on your policy; the clinic provides documentation, not coverage decisions.

What happens at the visit

The test itself takes a few minutes. You undress from the waist down and lie on an examination table. The doctor inserts a speculum to open the vagina gently and see the cervix, then uses a small soft brush or spatula to collect cells from the cervix. The sample goes into a liquid vial or onto a slide and is sent for analysis. Many women feel pressure or brief discomfort rather than pain, and light spotting afterward is common.

For 2 days before the test, avoid douching, vaginal sex, and vaginal medications or hygiene products, because they can wash away or hide the cells the lab needs. You can be tested during your period, but the sample is clearer at another time, so reschedule if you can. If you are also due for STI testing, ask for it at the same visit so that the samples can be taken together.

If you prefer a female doctor, say so when you book. Two of Podo's three OB-GYN specialists are women, and all three are board-certified specialists in obstetrics and gynecology. Consultations are available in English.

Results and an English copy for your doctor at home

Pap results are reported using a standard classification. Normal means no abnormal cells were seen. Other categories describe the type and degree of cell change, from mild changes that often go away on their own to changes that need closer examination. HPV results are reported as negative or positive, sometimes with the specific high-risk type identified.

The lab turnaround for a self-pay test is set by the lab the clinic uses and is told to you at the visit. For the national program, the designated institution has to notify you within 15 days.

If you want to continue care with your gynecologist at home, ask for a written copy of the result. Medical records and receipts are issued in English on request, so you can hand over a report that states the test performed, the date, and the result in terms a doctor in the United States, the UK or Australia will recognize. Keep it with your other records; the next doctor who screens you will want to know the date and result of your last test.

If the result is abnormal: colposcopy and follow-up

An abnormal screening result is common and does not mean you have cancer. Most abnormal results reflect cell changes caused by HPV that the body clears on its own or that can be treated before they become cancer. What happens next depends on the result and your age. Options include repeating the test after a set interval, adding an HPV test if you had only a Pap, or going on to colposcopy.

A colposcopy is a closer look at the cervix with a magnifying instrument, done in a clinic. It usually takes 15 to 20 minutes and you go home afterward. The doctor applies a liquid to the cervix to show up abnormal areas and may take a tissue sample about the size of a pin head, called a biopsy. If treatment is needed to remove abnormal cells, it is often done with a loop excision procedure, sometimes on the same day as the colposcopy and sometimes at a second appointment.

Podo performs colposcopy. If a lesion needs to be removed, it can be excised on the day of the visit, and the tissue is sent to a laboratory for biopsy. If you are leaving Korea soon, tell the doctor. The timing of follow-up can usually be planned around your travel, and your English report should state what follow-up is recommended so your doctor at home can take over.

Cervical screening and HPV vaccination at Podo

Gangnam Podo Women's Clinic is a women's clinic in Gangnam, Seoul, focused on gynecologic surgery and pelvic floor care. Consultations are available in English. The clinic is on the second floor of a building on Gangnam-daero, near Gangnam Station, and evening appointments are available on weekdays. Appointments are scheduled so that patients do not wait with other patients. Pap smear and HPV testing are part of the routine gynecology the clinic provides for international patients.

Podo offers the ThinPrep Pap test, a liquid-based Pap test in which the cells are rinsed into a vial of liquid rather than smeared on a slide, and an HPV test. Both can be done on the day of your visit. A TeleCervicogram, a digital imaging test of the cervix, is also available, and so is the Gardasil 9 HPV vaccine. If you have results from earlier screening abroad, bring them; the doctor reviews them.

Whether the clinic takes part in the national screening program and the fee for each self-pay test are confirmed at the consultation and stated in writing before anything is done. When you write, say which test you want, whether you have NHIS, and the date of your last screen.

This page is general information and is not a diagnosis; a consultation is needed to decide which test suits you. If you want to see an English-speaking gynecologist before you travel or move, write to us in English first.

Questions

Can I have a Pap smear during my period?

Yes, it is possible, but the sample is easier to read when you are not bleeding. If you can, book for a day outside your period.

I am a foreigner with NHIS. Is the national cervical screening for me too?

The program applies to NHIS-enrolled women aged 20 and over, on a two-year cycle, with no out-of-pocket cost for the Pap smear. Whether you are due in a given year depends on the cycle, so ask the clinic or check with NHIS before you book.

Does the national program include an HPV test?

No. The program covers a Pap smear. An HPV test or co-test is a separate self-pay item.

I had the HPV vaccine. Do I still need screening?

Yes. ACOG's vaccination guidance says vaccinated people still need cervical cancer screening, because the vaccine does not cover every high-risk HPV type. Follow the same schedule as everyone else.

Can I get the HPV vaccine in Korea as an adult?

HPV vaccination is recommended through age 26 and can be given to people through age 45 after a discussion with a doctor. Podo offers the Gardasil 9 vaccine; the doctor confirms at the consultation whether it suits you, and the fee is confirmed then too.

How do I say Pap smear in Korean?

The usual term is jagung-gyeongbu-am geomsa, meaning cervical cancer screening. At most clinics, saying Pap test in English is also understood.

Which cervical tests can I have at Podo?

Podo offers the ThinPrep Pap test, an HPV test and a TeleCervicogram, and these can be done on the day of your visit. Colposcopy is available too, and a lesion can be excised on the day of the visit with the tissue sent to a laboratory for biopsy. Bring any earlier results from abroad for the doctor to review.
