Prenatal Tests by Gestational Week
  • Prenatal testing is essential for maintaining healthy pregnancy and labor.
  • It is important for pregnant women and fetus to have regular checkups.

  • Tests During 10-35 Weeks
    After 10 weeks
    Fetus DNA Test
    (Non-Invasive Prenatal testing, NIPT)
    Analyze a small amount of fetal DNA in the mother's blood to determine the risk of chromosomal abnormalities, which includes Down Syndrome, Edward’s Syndrome, and Patau’s Syndrome.
    11~13 Weeks
    Integrated Screening Test (IST)/span>
    This is a screening test that can accurately detect fetal chromosomal abnormalities (especially Down syndrome) and neural tube defects. The newly introduced software calculates the risk of chromosomal abnormalities, nerves, and defects by combining both the thickness of the fetus’s neck and the concentration of proteins from the mother's blood.
    • Nuchal Translucency (measuring the fluid collection under the skin behind the fetal neck)
    • Blood Test (1st, 2nd)
    • Calculate the risk
    • Final results
    Chorionic Villus Sampling (CVS)
    This test is done when chromosomal diagnosis is necessary due to advanced maternal age or abnormal prenatal test results.
    Ultrasound
    Tests to check fetal growth, size, location and placenta position and shape.
    16~20 Weeks
    Amniocentesis, Maternal Serum Screening (2nd)
    This is a test to check for chromosomal abnormalities when the mother is aged 35 years or older, or if the prenatal tests or ultrasound findings are abnormal.
    Neural Tube Defects
    This is an examination for defects such as anencephaly and spina bifida.
    20~24 Weeks
    Level II Ultrasound & Fetal Echocardiography
    This is the simplest test to detect fetal anomalies, and is a test for structural abnormalities, including fetal heart malformations.
    24~28 Weeks
    Gestational Diabetes Test
    Tests are done for pregnant women with diabetes to prevent birth defects, infant diabetes and mortality.
    Blood Test, Liver Function Test
    This test is to check for changes in liver function and anemia in pregnant women.
    26~28 Weeks
    4D Ultrasound
    This is a test to closely observe the appearance abnormalities such as the fingers, toes, and face of the fetus (videos and pictures are recorded).
    After 32 Weeks
    Non-stress Test
    This is a test to diagnose the functional state of the fetus and mother. It measures the heart rate and uterine contraction of the fetus.
  • Tests After 35 Weeks
    Tests Before Delivery
    This test involves general blood test, liver function test, EKG, chest x-ray to prepare for any emergencies.
    Ultrasound
    This test is done to check the position and size of the fetus, placenta, and amniotic fluid and to determine the overall condition of the mother and fetus before delivery.
    Nonstress Test
    This is a test to diagnose the functional state of the fetus and mother. It measures the heartrate and uterine contraction of the fetus.
