Can birth defects be detected during pregnancy?

Contents show

Many types of birth defects can be diagnosed during pregnancy. A healthcare professional can use prenatal ultrasounds to help them diagnose certain birth defects in utero. More in-depth screening options, such as blood tests and amniocentesis (taking a sample of the amniotic fluid), may also be done.

Can you tell if your baby has birth defects before birth?

Tests used to diagnose birth defects may include amniocentesis (also called amnio). This test takes some amniotic fluid from around your baby in the uterus (womb) to check for birth defects and genetic conditions in your baby. You can get this test at 15 to 20 weeks of pregnancy.

Can you tell birth defects during pregnancy?

It’s not always possible to detect all birth defects in utero. However, high-resolution ultrasounds done by certified prenatal ultrasound groups make it possible to diagnose defects that will cause a significant impact before birth.

Can birth defects be seen on ultrasound?

Ultrasound is the most common tool used to detect birth defects. Doctors use an ultrasound to conduct a system-by-system analysis of the baby.
