Pregnancy is a time filled with many milestones—and a fair share of questions. One topic that can come up early is prenatal testing. If you’re expecting, you might wonder what these tests are for, whether you need them, and what the results might mean. Understanding your options can help you feel more confident and informed as you get ready for your baby’s arrival.

What Is Prenatal Testing?

Prenatal testing refers to a series of screenings and diagnostic tests offered during pregnancy. These tests are meant to provide you and your care team with important information about your baby’s health and development.

Some tests are routine, while others may be recommended based on your medical history, age, or previous pregnancies. These tests are completely optional, but many families find them reassuring or helpful for planning.

Types of Prenatal Tests

There are two main categories of prenatal testing: screening tests and diagnostic tests.

  • Screening tests estimate the likelihood of certain genetic conditions. These include blood tests and ultrasounds that check for things like Down syndrome or trisomy 18. They don’t give a definite answer, but they can show whether further testing might be needed.
  • Diagnostic tests provide more conclusive answers and include procedures like collecting samples of amniotic fluid or placental tissue. These tests are more involved and can carry a small risk, so they’re usually offered when screening results suggest a concern.

What Can These Tests Tell You?

Prenatal testing can provide information about:

  • Your baby’s growth and development
  • The risk of genetic or chromosomal conditions
  • Your own health during pregnancy, like your blood type or iron levels

It’s important to remember that prenatal tests are mainly to confirm that everything is progressing normally, which can be reassuring to parents and care teams.

Things to Consider Before Testing

It’s completely normal to feel a bit overwhelmed by all the options and appointments. Take the time to have a discussion with your provider about what information you want (or don’t want) to know, how results might influence your choices or care plan, and any personal or family history that might impact test recommendations.
