Pregnancy care is important for monitoring your and your baby’s health. Tests you may have during pregnancy include:
Sound waves are used to produce pictures of your baby. Ultrasound is often performed during your first clinic visit to check the viability of the pregnancy and estimate your due date. A second routine ultrasound is performed between 17 and 20 weeks to monitor the baby’s progress and possibly find out your baby’s gender. We also offer 3-D ultrasound when needed.
First Trimester Screening
Determines the risk for certain birth defects such as Down syndrome and Trisomy 18. Involves maternal blood tests and an ultrasound. Takes place between weeks 11 and 13 of pregnancy.
Chorionic Villus Sampling (CVS)
Tests for cystic fibrosis. Your doctor removes a small piece of tissue from the placenta to be tested for birth defects and genetic conditions. Can be done between weeks 10 and 12 of pregnancy.
Offered when the baby is suspected of having a genetic abnormality. A sample of amniotic fluid is drawn from the placenta using an ultrasound-guided needle inserted through the abdomen. Performed between weeks 14 and 20 of pregnancy.
AFP (Alpha-Fetoprotein)/Tetra Screen
Your blood will be drawn and tested for certain proteins that may indicate Down syndrome or neural tube defects such as spina bifida. Performed between weeks 15 and 19 of pregnancy.
Gestational Diabetes Screening
Screens for diabetes during pregnancy. Involves drinking a sugary liquid, followed by a blood draw about an hour later. Performed around 28 weeks.
Duke’s genetic counselors offer all aspects of genetic screening, as necessary, to determine your baby’s risk factors for fetal diseases and chromosomal abnormalities.
