Prenatal Tests: How It Helps Curve Down The Birth Defect Statistics

Many expecting parents still wonder to date. What causes birth defects? What exactly can be done to help lessen the risk of birth defects. To date, birth defect statistics remain to be at a constant point. Every year, approximately 3-5% of newborns born in the United States are affected with birth abnormalities. While yes, there remains no surefire procedure to help parents get rid of birth defects, there are ways which will help you lessen the risks of having to deal with birth abnormalities. One of which is by taking prenatal tests. Below, we will share with you the many types of prenatal tests that you may consider taking.

Alpha-fetoprotein screening - The fetus produces alpha-fetoprotein between the 16th and 18th week. Alpha-fetoprotein is substance produced by the fetus and can be measured by testing the woman's blood. If it is found out that the pregnant woman contains a high level of such substance, there is a big chance that the fetus has neural tube defects. In some cases, the high level of alpha-fetoprotein may also be an indication that there was a misconception on the date of conception. On the other hand, if the level is low, there is a chance for chromosomal abnormalities like Down Syndrome.

Multiple marker screening – Your doctor can also measure the level of hormones in your blood. For this particular screening, the doctor uses a sample of the blood from the mother to measure the level of alpha-fetoprotein, estriol and human chorionic gonadotropin. All these substances will help the doctors identify if the fetus is facing high risks of birth defects.

Amniocentesis - The physicians uses a needle to help remove the amniotic fluid from the womb of the mother. Such exam is performed between the 15th and the 20th week. The fluid specimen can help identify fetal abnormalities like spina bifida and Down Syndrome. More often than not, this prenatal exam is recommended only if the mother and the baby is believe to be at risk.

Chorionic villus sampling – This process is performed during the first trimester of the pregnancy. Again, it takes a sample of the tissue which attaches the amniotic sac to the uterus. Like the previous test, this exam is only done if physicians see a potential risk of birth defect.

Ultrasound – Every pregnant woman is required to have at least one ultrasound to make sure that the pregnancy is normal and to verify the delivery date. In most cases, the ultrasound is performed when the fetus is between the 18th and the 20th week. This; however, may also be done sooner and more than once throughout the pregnancy. Parents do not have to worry about anything because ultrasound does not pose any harm to the baby nor to the mother.

There are a variety of tests which can be considered by the parent. All these can help lessen your risks of giving birth to a baby with birth defect. Ask your physician what suits you best.
