Prenatal Tests

[*NEW*] Patients of Thomson Fetal Assessment Unit can now view their baby’s development on the go with Ultragram App

Fetal Assessment Unit

The Fetal Assessment Unit (FAU) provides a one-stop obstetric ultrasound and pre-natal diagnostic service for pregnant women who wish to be assured of the well-being of their babies. This unit is the first dedicated unit in a private hospital in Singapore and is managed by a Consultant Maternal Fetal Medicine Specialist and is assisted by a team of experienced and dedicated sonographers.

Our Fetal Assessment services include:

• First Trimester Pre-Eclampsia Screening:

Pre-eclampsia is a serious pregnancy complication affecting 2 in 100 pregnancies. It is a common cause of preterm birth and intrauterine growth retardation. We are the 1^st centre in Singapore to offer this screening which includes

– Specific blood test for PlGF*

– Blood pressure measurement

– Ultrasound examination

1^st Trimester Pre-Eclampsia Screening and early treatment helps to prevent pre-eclampsia.

Consult your doctor and book an appointment with us for 1^st Trimester Pre-Eclampsia Screening. Call us @ 63544115 or download our e-brochure for more information

• One-stop Clinic for Assessment of Risk for Fetal Anomalies (OSCAR)

This is a first trimester option offered to all pregnant women as an earlier and more accurate method of screening for risk of fetal anomalies, in particular Down Syndrome (Trisomy 21).

1. Screening for chromosomal defects in the first rather than the second trimester provides earlier reassurance for those with a normal result.
2. The composite risk score will help you decide whether you want any invasive testing such as CVS or Amniocentesis.
3. For those choosing this optional test, it will also be less traumatic if a termination is necessary.

What does OSCAR involve?
1. Ultrasound measurement of Nuchal Translucency (NT) at 11-13 weeks + 6 days gestation of the fetus.
2. A sample of the mother’s blood is analysed for levels of free beta hCG and PAPP-A (Pregnancy associated plasma Protein A).
Studies have shown that Down Syndrome is associated with
• Increased maternal age
• Increased fetal nuchal translucency thickness (NT)
• Increased maternal serum free beta-hCG and
• Decreased pregnancy-associated plasma protein A (PAPP-A) concentration

The detection rate of Trisomy 21 by this method would be about 90%, for a false positive rate of 5%. This is superior to the 65% by maternal age and second trimester serum biochemistry; and 80% detection rate by NT and maternal age in the first trimester.

For detailed information on OSCAR, please download our e-brochure.

• 3D/4D Ultrasound Scans
  

Fancy taking a peek at your little bundle of joy? With our latest 3D/4D ultrasound scans, you are able to see your unborn child for the first time. A 3D ultrasound scan provides a photographic image of the baby while the 4D ultrasound scan provides a moving image of a baby.

At Fetal Assessment Unit, the 3D/4D ultrasound scans will be performed in a relaxed and comfortable environment by our experienced sonographers using state-of-the-art ultrasound systems.

A 2D scan will still be performed in conjunction with the 3D/4D scan to exclude anomaly and assess the growth of the baby. To experience this amazing and touching moment, just obtain a referral letter from your doctor and book an appointment with us at 6354 4115.

For detailed information on the 3D/4D scan, please download our e-brochure.

Other Services available at FAU include
• Ultrasound imaging for risk assessment of chromosomal abnormalities in the first trimester (Nuchal Translucency Measurement)
• Second trimester Fetal Anomaly (FA) Scanning
• Cervical Length Measurements for prediction of pre-term labour
• Uterine Doppler assessment for prediction of pre-eclampsia and poor fetal growth
• Ultrasound monitoring using Doppler colour flow imaging, as well as the
biophysical profile
• Amniocentesis
• Thalassaemia Studies
• Chorionic Villus Sampling
• Cordocentesis/Fetal Blood Sampling
• Multiple pregnancy (twins/triplets/quadruplets) fetal assessment

Here are some screening tests services recommended for different trimester, please do consult your doctor for advice on which screening test to take for your condition :

   1^st Trimester:

• First Trimester Pre-Eclampsia Screening
• Either OSCAR (One-stop Clinic for Assessment of Risk for Fetal Anomalies ) or
• NT plus NIPT – Panorama/Harmony
• Chorionic Villus Sampling

    2^nd Trimester:

• Fetal Anomaly Scan –Obstetric Ultrasound (20 to 22 weeks)
• Fetal Anomaly Scan with Uterine Doppler (20 to 22 weeks)
• Cervical Length Assessment
• Amniocentesis

    3^rd Trimester

• Obstetric ultrasound for Growth with Full Doppler to assess fetal growth and well-being
• Obstetric ultrasound without Doppler to assess growth.
• Biophysical Profile

产前评估门诊

产前评估门诊（FAU）是新加坡首家由私立医院设立的专业胎儿健康检测机构，由一流母胎医学专家坐诊咨询，配备经验丰富的专业超声波检验师队伍，为广大孕妇提供一站式产科超声波与产前基因检测，贴心关爱母婴身心健康。

产前评估门诊服务包括：

• 第一妊娠期子痫前症筛查：

 子痫前症是一种严重孕期疾病，发生率约为2％，是导致早产和胎儿宫内发育迟缓的常见原因。我们的护理团队率先在新加坡推出下列针对性筛查服务：

——抽血检查胎盘生长因子

——血压测量

——超声波检查

在第一妊娠期的早期子痫前症筛查与早期治疗能够有效防治子痫前症。

欢迎垂询预约第一妊娠期子痫前症筛查事宜。

请拨打服务热线63544115或下载电子服务手册，了解更多相关信息。

•  一站式胎儿异常风险评估服务 (OSCAR)

这是我们为广大孕妇推出第一妊娠期胎儿异常风险的筛查服务，时间更早，精度更高，尤其适用于筛查唐氏综合征（21-三体综合征）。

1. 染色体异常筛查在第一妊娠期开展，而非延迟到第二妊娠期，尽早确保母婴健康。
2. 开展全面综合风险评分，有助于确认是否需要绒毛膜取样术或羊膜穿刺术等创伤性检测。
3. 及早检测与诊断胎儿异常，如需终止妊娠，对母亲带来的身心创伤也会相对减少。

一站式胎儿异常风险评估服务具体包含哪些项目？

1. 孕11-13周＋6天胎儿颈项透明层(NT)厚度超声波测量。
2. 孕妇抽血检测游离绒毛膜促性腺激素与妊娠相关血浆蛋白A（PAPP-A）的水平。

研究发现，唐氏综合征与下列因素相关：

• 孕妇高龄
• 胎儿颈项透明层(NT)过厚
• 孕妇游离绒毛膜促性腺激素水平过高
• 妊娠相关血浆蛋白A（PAPP-A）浓度过低

本筛查项目中，21-三体综合征的检测准确率大约为90％，假阳性率为5％，远高于结合孕妇年龄与第二妊娠期母血清生化指标等数据进行筛查的65％检测准确率，以及结合孕妇年龄与第一妊娠期胎儿颈项透明层厚度测量等数据进行筛查的80％检测准确率。
