Prenatal testing can provide valuable information about your baby's health. These tests are optional, but if you are considering any, it is important you make informed decisions.
Some questions to consider and discuss at length include:
- What do the test results determine or diagnose?
- How accurate are the results?
- How will the information affect my prenatal care?
- What are my risks?
There are many ways to help ensure a safe pregnancy and delivery of a healthy baby. Besides practicing good health habits and nutrition, you can speak with your doctor about prenatal testing. These tests range from commonly used techniques like ultrasound to advanced screening for those whose babies may have a high risk of birth defects.
Some common forms of prenatal testing are:
- Chorionic Villus Sampling
In this test, a small sample of cells is taken from the placenta, either through a catheter or a needle. Your doctor can determine from these cells whether there are any potential defects in chromosomes. Chorionic Villus Sampling is normally performed in the first trimester of pregnancy.
- Maternal Serum Alpha-Fetoprotein testing
MSAFP is a blood test that helps to identify pregnant women who have high blood levels of alpha-fetoprotein, which carries an increased risk of a baby being born with an open neural tube defect (like spina bifida). This test can also diagnose chromosomal defects contributing to conditions such as Down syndrome or trisomy 18. This test only assesses the potential for problems, and cannot provide a definitive diagnosis.
Amniocentesis involves taking a sample of amniotic fluid – the fluid which surrounds your baby during pregnancy – through a needle carefully inserted into the uterus through the abdomen. Amniocentesis is used to check for chromosomal defects as well as other potential conditions.
Ultrasound is one of the most commonly used procedures in prenatal screening and routine prenatal care. Using high-frequency sound waves to create images of internal organs, ultrasound imaging is safe and useful for assessing the development of your baby. Your doctor uses these images to address any concerns and give you a first look at your little one.
