HPV self-sampling test in Taichung: how it differs from a Pap smear
With self-sampling you take the sample yourself, at home. It answers one question: is a high-risk type of HPV present? It cannot answer what a Pap smear answers: whether the cells of the cervix have changed.
Explained by Dr. Chao-An Chen, urologist, at 昭安泌尿科診所 (Morning Urology Clinic), West District, Taichung.
In short
- It tests the virus, not the cells. You take a sample from the vagina yourself. The laboratory then reports whether a high-risk type of HPV is present, and which type it is. It does not examine the cells of the cervix.
- It does not replace a Pap smear. A Pap smear is a sample of cells taken from the cervix by a doctor and examined under a microscope, to look for early change before cancer. Self-sampling cannot do this.
- It is meant to make the first test easier. Many women have not been screened for a long time, because of time, travel or worry. Starting matters more than which method you start with.
- A positive result does not mean cancer. Most infections clear by themselves over a period of time. The next step is a Pap smear, or an examination of the cervix called colposcopy, arranged by a gynaecologist.
- If you already have symptoms, see a doctor instead. Abnormal bleeding, a change in discharge, or an abnormal Pap smear result in the past: in all of these the sample should be taken by a doctor, who also examines you.
- Public screening programmes are separate from this clinic. They are run by the health authority, which sets the rules on who qualifies. Costs are explained at the consultation.
What the test looks for
Human papillomavirus (HPV) is a very common virus that is passed on by sexual contact. It is the main cause of cervical cancer, especially the high-risk types such as type 16 and type 18. For many years the main way to find early change has been the Pap smear, taken by a doctor, which looks for abnormal cells.
An HPV DNA test works in a different way. It examines the sample for the virus itself, and reports which type is present. This is what a self-collected sample is used for.
HPV has many types. The high-risk types, such as 16 and 18, are the ones linked to cervical cancer. Types 6 and 11 mainly cause genital warts (condylomata acuminata). If you or your partner can already see a lesion, the situation is different: a sample can only tell you whether the virus is present, while the decision about treating a lesion belongs to a doctor. That is covered on our page about genital warts and HPV (Chinese).
Where self-sampling fits in Taiwan
Self-sampling is not a new idea in Taiwan. From 2010 the Health Promotion Administration (then the Bureau of Health Promotion) offered an HPV self-sampling service to two groups of women: those aged 36 and over who had not had a Pap smear for six years or more, and those aged 30 and over with a disability. Women whose result was positive were then helped to have a Pap smear, so that any change in the cells could be confirmed.
That design shows the role of self-sampling. It is the first step — finding out whether a high-risk type is present. A Pap smear still comes after it. It was never meant to replace one.
Public screening in Taiwan has since been widened. From 2025 the Ministry of Health and Welfare expanded cancer screening: the Pap smear subsidy was extended to women aged 25 to 29 once every three years, women aged 30 and over are advised to have a Pap smear at least once every three years, and an HPV test was added once each at the ages of 35, 45 and 65.
Those are public programmes. The health authority decides who qualifies for them, not this clinic, so please check your own eligibility with the health authority. At this clinic, if you are not enrolled in Taiwan’s National Health Insurance, the consultation and tests are self-paid.
Who it suits, and what it cannot answer
Most women who consider self-sampling have not been screened for a long time. The reason is usually time, travel, or an uncomfortable feeling about the examination itself. With self-sampling you take the sample yourself, so that a woman with no screening record at all can at least learn whether a high-risk type is present.
The limit of the test has to be clear. A self-collected sample tests the virus, not the cells. A Pap smear shows whether the cells of the cervix have started to change before cancer, and self-sampling cannot do this. It is a way to start, not a substitute for a Pap smear.
Do not use self-sampling in place of a consultation if you have any of these:
- abnormal bleeding;
- a change in vaginal discharge;
- an abnormal Pap smear result in the past.
In these situations the sample should be taken by a doctor, and you should be examined at the same visit.
The two ways of sampling, side by side
| Sampling at a medical institution (Pap smear, or HPV sample taken by a doctor) | Self-sampling (you take a vaginal sample for HPV testing) | |
|---|---|---|
| Who takes the sample | A doctor or another health professional takes a sample from the cervix | You take a sample from the vagina yourself |
| What is tested | The smear shows the appearance of the cervical cells; an HPV type test can be added when needed | The HPV type only; the cells are not examined for change |
| What the result answers | Whether the cells now show change before cancer | Whether a high-risk type of HPV is present now |
| How it is done | In a consulting room by the medical team; you register and wait for your turn | At home, following the leaflet, then sent to the laboratory |
| If the result is abnormal | The doctor then arranges colposcopy, a biopsy and similar tests | You still need to attend a medical institution for a Pap smear or colposcopy |
| Its place in screening | The basis of cervical cancer screening and of follow-up | A first step, to raise the number of women screened; it cannot replace a Pap smear |
The result of a self-collected sample is returned to you in a private way.
Four steps at home
The kit comes with an instruction leaflet. There are only a few steps, but the order matters: it keeps the quality of the sample steady. The outline below is the general flow. The leaflet supplied with your own kit comes first.
- Prepare. Wash your hands and dry them. Open the kit in a comfortable, private space.
- Insert. Choose the position in which you feel most relaxed — for example one foot resting on the toilet, or a half-squat. Insert the brush gently into the vagina.
- Collect. Turn the brush gently a few times as instructed, usually three full turns, so that enough secretion from the vaginal wall is collected.
- Send it back. Put the brush into the collection tube, break off the handle, close the cap firmly, and return it to the laboratory as instructed.
Return the sample within the time limit stated in the leaflet. A sample that is kept too long before it reaches the laboratory can affect how the result is read.
Reading the report
You can take the sample on your own. Reading the report, and deciding the next step, still needs a doctor, who considers your age, your symptoms and your past screening record together.
If the result is negative
No high-risk type of HPV was found in this sample. That is not the same as no risk. A self-collected sample is not examined for change in the cells, and the way the sample was taken and its timing can both affect the result. You should still have Pap smears at the recommended interval.
If the result is positive
Finding a high-risk type does not mean you have cancer. Most infections clear by themselves over a period of time. What follows is a Pap smear or a colposcopy, arranged by a gynaecologist, to confirm whether the cells have changed. The result of that test then sets the interval for follow-up.
On the scope of the test: this screening kit covers the HPV type only. It does not include reading a smear for cell change that may be malignant.
Vaccination and screening are two separate things
Vaccination is prevention. It works only against the types it covers, and only for types you have not already acquired. It does not replace screening, and it cannot clear an infection that is already there. Whether it suits you, and how many doses you need, is assessed by a doctor from your age and your vaccination history. Our page on the 9-valent HPV vaccine, listed below, sets this out.
One point often surprises people: HPV is not part of a general sexually transmitted infection screening panel. The two have to be planned separately. If you want both, please say so at the visit.
Your visit: what to bring, what happens
- Book through the online form, LINE, or by telephone.
- Registration. Please bring your passport or resident certificate; it is needed to create the medical record. If you are not enrolled in Taiwan’s National Health Insurance, the consultation and tests are self-paid.
- Consultation. Your age, any symptoms and your past screening record are reviewed together. This is also where it is decided whether self-sampling is the right starting point for you, or whether a doctor should take the sample instead.
- After the report. If the result is negative, the doctor explains where it leaves your Pap smear schedule. If it is positive, a Pap smear or colposcopy is arranged with a gynaecologist.
Useful to bring: the dates and results of any previous Pap smears or HPV tests, your HPV vaccination record if you have one, and a note of anything you have noticed, such as bleeding between periods or a change in discharge.
The clinic has separate consulting rooms and a divided patient flow, so you do not have to explain why you have come while you are in the waiting area.
Frequently asked questions
My result is negative. Can I skip the Pap smear?
No. A negative result means that no high-risk type was found in that sample. It does not examine the cells of the cervix, and sampling method and timing can affect it. Please keep to the recommended interval for Pap smears.
I have never been screened. Where should I start?
Anywhere, as long as you start. Long-lasting infection with a high-risk type is the main cause of cervical cancer, and the value of screening is that it finds change early. Which method you begin with matters less than beginning.
Does a positive result mean I have cancer?
No. Most infections clear by themselves over a period of time. The next step is a Pap smear or colposcopy arranged by a gynaecologist, to see whether the cells have changed.
Which parts are done here, and which are referred?
Screening and prevention are one of the four areas in the clinic’s services for women, along with bladder and pelvic floor problems, contraception, and weight and metabolism. The assessment, arranging the test and explaining the report are done here. A Pap smear or a colposcopy is arranged with a gynaecologist.
Can the vaccine deal with an infection I already have?
No. Vaccination prevents infection with the types it covers. It cannot clear an infection that is already present, and it does not replace screening.
