A nonstress test is a common prenatal test used to check on a baby's health. During a nonstress test, the baby's heart rate is monitored to see how it responds to the baby's movements. The term "nonstress" refers to the fact that nothing is done to place stress on the baby during the test.
Certain nonstress test results might indicate that you and your baby need further monitoring, testing, or special care.
A nonstress test is a noninvasive test that doesn't pose any physical risks to you or your baby.
Your health care provider might recommend a nonstress test if you have:
A multiple pregnancy
An underlying medical condition, such as type 1 diabetes, heart disease high BMI or high blood pressure during pregnancy
A history of complications in a previous pregnancy
A baby who has decreased fetal movements or possible fetal growth problems
Low amniotic fluid (oligohydramnios)
Advanced maternal age
Your health care provider might recommend having nonstress tests once or twice a week depending on your health and your baby's health.
