STI screening during pregnancy is not just recommended - it is one of the most important steps you can take to protect your baby. Many sexually transmitted infections can be passed from mother to baby during pregnancy or birth, but most are easily treatable when caught early. Singapore's antenatal care programme includes routine STI screening for all pregnant women.
Why STI Screening Matters in Pregnancy
Some STIs cause no symptoms in the mother but can have serious effects on the baby. For example:
- Syphilis can cause stillbirth, premature birth, and serious birth defects
- HIV can be transmitted to the baby during pregnancy, birth, or breastfeeding
- Hepatitis B can infect the baby during delivery
- Chlamydia and gonorrhoea can cause eye infections and pneumonia in newborns
The good news is that with early detection and treatment, most of these risks can be significantly reduced or eliminated.
Which STIs Are Screened in Singapore
| Infection | How It Is Tested | When Tested |
|---|---|---|
| Syphilis (VDRL) | Blood test | First antenatal visit |
| HIV | Blood test | First antenatal visit |
| Hepatitis B (HBsAg) | Blood test | First antenatal visit |
| Rubella immunity | Blood test | First antenatal visit |
| Group B Streptococcus (GBS) | Vaginal swab | 35 to 37 weeks |
When to Get Screened During Pregnancy
Most STI screening happens at your first antenatal visit, ideally before 12 weeks. This is the most important window because early treatment is most effective. Your obstetrician or polyclinic doctor will order these tests as part of the standard first-visit blood panel. Use the Prenatal Appointment Scheduler to make sure you do not miss key check-ups.
What Happens If a Test Comes Back Positive
A positive result is not a reason to panic. Most conditions are treatable during pregnancy:
- Syphilis - treated with penicillin, which is safe during pregnancy and very effective
- HIV - antiretroviral therapy reduces the chance of transmission to near zero
- Hepatitis B - your baby receives the Hepatitis B vaccine and immunoglobulin at birth as protection
- GBS - antibiotics are given during labour to protect the baby
Your doctor will guide you through the next steps. Confidentiality is maintained, and all antenatal records in Singapore are private.
