What you can expect

A nonstress test is usually done in your health care provider's office.

Before the procedure

You'll have your blood pressure taken before the nonstress test begins.

During the procedure

During the nonstress test, you'll lie on a reclining chair. You'll have your blood pressure taken at regular intervals during the test.

Your health care provider or a member of your health care team will place a sensor around your abdomen that measures the fetal heart rate.

Typically, a nonstress test lasts 20 minutes. However, if your baby is inactive or asleep, you might need to extend the test for another 20 minutes — with the expectation that your baby will become active — to ensure accurate results. Your health care provider might try to stimulate the baby by placing a noise-making device on your abdomen.

After the procedure

After the nonstress test is complete, your health care provider will likely discuss the results with you right away.
