Regular screening can help in the prevention of cervical cancer. Since most sexually transmitted infections do not cause any symptoms, you would have no way of knowing that you had one unless you underwent testing. A Pap smear, an HPV test, and an STI panel all look for different things. The following guide will tell you what each test is for, when you may need it, and how much it costs in Singapore.
Cervical Screening in Singapore
Pap Smear vs HPV Test: The Clinical Difference
It is easy to mix up these two tests, but knowing the difference helps you get the right care.
A Pap smear collects cells from your cervix and checks them under a microscope for any abnormal changes. This test tells you whether your cervical cells are normal right now.
An HPV test looks for high-risk HPV strains, which are the viruses that cause most cervical cancers. This test does not check your cells directly. Instead, it tells you if a cancer-causing virus is present.
Both tests help you understand your risk of cervical cancer, but they work in different ways. The HPV test is better at finding long-term risk. The Pap smear is more specific for changes happening in your cells right now.
Which You Should Have at Which Age
Singapore’s national cervical screening programme recommends:
- Women aged 25 to 29: Pap smear every 3 years
- Women aged 30 to 69: HPV test every 5 years (more sensitive for long-term risk at this age)
If you are under 30, HPV testing is not usually recommended. This is because HPV infections are common at younger ages and your immune system often clears the virus on its own. A positive HPV result before age 30 usually goes away by itself and does not mean you have a high risk of cancer.
If you are a woman aged 25 to 69 and have ever been sexually active, you should get screened. This is important even if you have had the HPV vaccine, because the vaccine does not protect against every cancer-causing strain.
The National Screening Programme and Subsidies
Singapore’s Screen for Life (SFL) programme makes cervical screening highly affordable for eligible women:
- Healthier SG enrolled citizens: SGD $0 at their enrolled clinic
- CHAS Blue/Orange cardholders: SGD $2 to $5 at participating CHAS GP clinics
- Polyclinics: Pap smear SGD $15, HPV test SGD $22.50 for Singapore Citizens
How Often to Screen
How often you need screening depends on your age and the type of test you have.
- If you are between 25 and 29, you should have a Pap smear every 3 years.
- If you are between 30 and 69, you should have an HPV test every 5 years.
- If your results are abnormal, your doctor will recommend a shorter follow-up, usually in 6 to 12 months.
You should continue screening until age 69 if you have been sexually active. If you have had a total hysterectomy for non-cancerous reasons, you may not need further screening. Talk to your doctor to be sure.
What a Pap Smear Does NOT Check For
This is one of the most misunderstood parts of cervical screening, and you need to know.
A Pap smear only checks the cells of your cervix. It does not:
- Detect STIs: Chlamydia, gonorrhoea, syphilis, HIV, herpes, and other infections will not be found by a Pap smear.
- Screen for ovarian cancer: There is no routine blood or swab test that reliably checks for ovarian cancer.
- Detect endometrial (uterine) cancer: A Pap smear does not sample the lining of your uterus.
- Confirm pregnancy or fertility: A Pap smear does not give you information about your ovarian reserve, fallopian tubes, or hormone health.
- Replace an STI panel: A normal Pap smear does not mean you are free of STIs.
If you want to be tested for STIs, you need to ask for it. STI testing is a separate set of tests.
STI Testing
What a Standard Panel Covers
If you take a standard STI panel in Singapore, you can expect it to include the following tests:
- HIV (types 1 and 2)
- Chlamydia
- Gonorrhoea
- Syphilis
- Hepatitis B and C
Some panels may also check for herpes simplex (HSV-1 and HSV-2), but this is not routine. You can read more about this below.
What It Misses
A standard STI panel does not automatically test for the following infections:
- Herpes (HSV) is not routinely tested unless you have symptoms. A blood test can detect antibodies, but it cannot tell you when you were infected or if you will develop symptoms.
- Mycoplasma genitalium is an STI that is becoming more recognised. It is not included in most standard panels, but it can cause urethritis and pelvic inflammatory disease.
- Trichomoniasis is sometimes missed in standard panels. If you have symptoms, ask your doctor to test for it specifically.
- HPV is not included in general STI screening for women. Cervical HPV testing is only done as part of cervical cancer screening, not as part of a standard STI panel.
If you have specific concerns or symptoms, talk to your doctor about which infections you want tested. Do not assume that a standard panel covers everything.
Window Periods for Each Infection
If you test too soon after exposure, your results may be falsely negative. The window period is the time between when you are exposed and when a test can reliably detect the infection:
| Infection | Window periods |
| HIV (4th generation Ag/Ab test) | 18 to 45 days; most accurate after 45 days |
| Chlamydia | 1 to 2 weeks |
| Gonorrhoea | 1 to 2 weeks |
| Syphills | 3 to 6 weeks |
| Hepatitis B | 6 weeks to 3 months |
| Hepatitis C | 8 to 11 weeks |
| Herpes (blood antibody test) | 12 to 16 weeks for the most reliable result |
If you have tested within the window period after a potential exposure, repeat testing after the window has passed.
Pelvic Exam vs Pap Smear vs STI Panel: The Differences
You might think these three are the same, but they are not.
| During a pelvic exam, your doctor checks your external genitalia, looks inside your vagina and cervix with a speculum, and may feel your uterus and ovaries with their hands. This is an assessment, not a test. No samples are sent to a laboratory. | A Pap smear is a laboratory test. Your doctor collects cells from your cervix during a pelvic exam and sends them for analysis. A pelvic exam does not automatically include a Pap smear. You need to ask for it, or make sure it is scheduled as part of your appointment. | An STI panel is a different set of tests. Your doctor may take blood or swabs and send them to a laboratory to check for specific infections. An STI panel is not included in a routine pelvic exam or Pap smear unless you ask for it. |
You can have all three done in one visit at most clinics, but you need to ask for each one clearly.
HPV Vaccination, Testing, and What a Positive Result Means
HPV is the virus that causes almost all cervical cancers. If you are sexually active, you will probably have an HPV infection at some point. The good news is that most HPV infections clear on their own within 1 to 2 years and do not cause any harm.
Vaccination: The 9-valent HPV vaccine (Gardasil 9) protects against 9 HPV types, including the two highest-risk strains, HPV 16 and 18. These two strains cause about 70% of cervical cancers. In Singapore, the vaccine is recommended for girls and boys aged 9 to 26. If you are older than 26, you can still get vaccinated, but MediSave only covers the cost up to age 26. Remember, vaccination does not replace regular screening. The vaccine does not protect against every cancer-causing HPV strain.
If you have a positive HPV test, it does not mean you have cancer or that you will get cancer. It simply means a high-risk HPV strain was found. Your doctor will guide you on next steps. This may include a repeat test, a Pap smear, or a colposcopy, depending on your results and screening history.
What to Expect During the Appointment
You might feel unsure about screening or remember a past appointment that was uncomfortable. Here is what you can expect:
For a Pap smear or cervical swab:
You will lie on an examination table with your knees bent and apart. Your doctor will gently insert a smooth plastic or metal speculum to open your vaginal canal so your cervix is visible. They will use a small brush or spatula to collect cells from your cervix. This part takes about 10 to 30 seconds. You may feel mild pressure or brief discomfort, but it should not be painful. The whole appointment usually takes 5 to 15 minutes.
Tips that help:
- Try to avoid sex, douching, or using vaginal creams for 24 to 48 hours before your test.
- If you can, schedule your appointment outside your period. Testing during a light period is still okay.
- If you feel anxious, tell your doctor. They can slow down and explain each step to help you feel more comfortable.
For an STI blood test:
For an STI blood test, you will have a standard blood draw, just like any other blood test. Some STI tests may also need a urine sample or a swab from your cervix, vagina, or throat, depending on what is being checked.
Understanding Your Result
Pap smear results:
- Your result is normal, which means no abnormal cells were found. You can simply continue with your regular screening schedule.
- If your result shows ASC-US, this means there are mildly abnormal cells. Your doctor may recommend an HPV test or ask you to repeat your Pap smear in 6 to 12 months. This helps make sure everything stays on track.
- If you see LSIL or HSIL on your result, this means there are abnormal cell changes. Your doctor will likely recommend a colposcopy to take a closer look and decide what to do next.
HPV test results:
- A negative HPV test means no high-risk HPV was found. You can repeat the test in 5 years as part of your routine care.
- If your HPV test is positive, this means high-risk HPV is present. Your doctor will discuss next steps with you, which may include a Pap smear or colposcopy, depending on your specific situation.
STI results:
- A negative STI result means no infection was found at this time. If you tested during the window period, you may need to repeat the test after enough time has passed to be sure.
- If your STI result is positive, your doctor will discuss treatment options with you. Most STIs can be fully treated or managed, so support and solutions are available.
Where to Go
Polyclinics
If you are looking for the most affordable way to get cervical screening, polyclinics are a good choice. You can get Pap smears and HPV tests at subsidised rates through ScreenForLife. Waiting times can be longer, so book your appointment in advance. Every polyclinic across the island offers cervical screening.
DSC Clinic
If you need thorough STI screening, the Department of STI Control (DSC) Clinic at Kelantan Lane is Singapore’s main public STI clinic. Here, you can access comprehensive STI testing, treatment, and counselling at subsidised rates. If you have complex STI concerns or need a post-exposure assessment, this is the best place to start.
Private GPs and Women’s Clinics
If you prefer shorter waiting times and more flexible appointments, private clinics may suit you better. You can also build a consistent relationship with your doctor, which many women find important for intimate health. Most private GP clinics offer Pap smears, HPV tests, and STI panels. Dedicated women’s clinics, such as Raffles Women’s Centre, Singapore Women’s Clinic, and W Gynae, provide comprehensive cervical and STI screening. You can also get specialist gynaecology input if you need it.
