Getting to the clinic
Dr Tony Tan runs the Tony Tan Women and Fetal Clinic at Mount Alvernia Hospital in the Thomson area, and holds admitting privileges across a number of major private hospitals in Singapore. For the Mount Alvernia location, many patients find a taxi or ride-hailing service the most convenient option, as the hospital sits a little away from the nearest MRT; you can be dropped off directly at the entrance. The nearest stations are around the Marymount and Novena areas, from which a bus or taxi completes the journey.
Bus services run along the roads near the hospital, and Mount Alvernia has a paid visitor carpark for those who drive, which can be busy during clinic hours. As Dr Tan also sees patients across other private hospitals, it is worth confirming the exact location of your appointment when you book, since each campus has its own access and parking arrangements. For pregnant patients, a direct taxi drop-off at the hospital entrance is often the most comfortable choice. Reception staff can direct you to the correct floor and suite on arrival.
What maternal-fetal medicine covers
Dr Tony Tan’s subspecialty is maternal-fetal medicine, the care of high-risk and complex pregnancies. This field supports women whose pregnancies need closer monitoring, and assesses the wellbeing of the baby before birth. His clinical interests include:
- Twin and other multiple pregnancies, which require closer surveillance.
- Fetal abnormality screening and diagnosis, including detailed ultrasound assessment of the baby.
- Preterm labour and the risk of early delivery.
- Pre-eclampsia, a condition involving raised blood pressure in pregnancy.
- Intrauterine growth restriction, where the baby is not growing as expected.
Maternal-fetal medicine combines specialised ultrasound and screening with careful monitoring throughout pregnancy. The aim is to identify and manage risks early, support the health of both mother and baby, and provide clear information so that families can make informed decisions.
What to expect at a consultation
A visit usually begins with a discussion of your pregnancy, medical and obstetric history and any concerns raised at earlier scans or tests. Detailed ultrasound is central to this field, used to assess the baby’s growth, anatomy and wellbeing. Depending on the situation, screening tests, blood tests or further diagnostic procedures may be discussed. The specialist will explain the findings in clear terms, outline any risks identified and discuss the options for monitoring or management. For high-risk pregnancies, a plan for ongoing surveillance through the pregnancy is usually set out.
Preparing for your appointment
It is helpful to bring the following to your visit:
- Photo identification and any GP, polyclinic or obstetrician referral letter.
- Your antenatal records, previous scan reports and any screening or blood test results.
- A current list of medications and supplements, including those taken in pregnancy.
- A written list of your symptoms and questions.
- Details of any relevant family or obstetric history, such as previous pregnancy complications, which are particularly important in high-risk care.
After your consultation and follow-up
After the appointment, the findings from scans and tests are explained, and a plan for the rest of the pregnancy is usually agreed. High-risk pregnancies often need repeated review and scans to monitor the baby’s growth and wellbeing over time, and the schedule is tailored to your situation. Where a particular concern is identified, further tests or referrals may be arranged, and care is coordinated with your delivering obstetrician and hospital. You are welcome to seek a second opinion. Seek urgent attention for warning signs such as reduced fetal movements, vaginal bleeding, severe headache, a sudden swelling, abdominal pain or signs of labour before your due date.
Booking, referrals and fees
Appointments with a private specialist can usually be made directly, though many maternal-fetal medicine patients are referred by their own obstetrician or GP, and a referral letter helps by sharing your history. For eligible procedures and deliveries, MediSave, MediShield Life and Integrated Shield Plans may contribute within the limits that apply, while consultations and scans are generally paid out of pocket. As coverage varies by plan, hospital and procedure, confirm the details and any estimates directly with the clinic and your insurer.
Common questions
What makes a pregnancy “high-risk”?
A pregnancy may be considered higher risk because of factors such as carrying twins, a medical condition, a previous complication, or a concern found on a scan. Closer monitoring helps manage these situations.
Will I still see my own obstetrician?
Maternal-fetal medicine care is often provided alongside your regular obstetrician, with the specialist focusing on the higher-risk aspects and coordinating care.
Are detailed ultrasound scans safe in pregnancy?
Ultrasound is a widely used and well-established tool in pregnancy care. The specialist will explain the purpose of each scan recommended for you.
What warning signs should prompt urgent attention?
Reduced fetal movements, vaginal bleeding, severe headache, sudden swelling, abdominal pain or signs of early labour should prompt prompt medical attention rather than waiting.
