Nonstress Test (NST)

A nonstress test uses electronic monitoring to check the health of an unborn baby. An external fetal monitor is attached to the mother and records the baby's heart rate. When a healthy baby moves, the baby's heart rate goes up.

You may have this test if:



You have a high-risk condition, such as high blood pressure or a baby that is not growing properly.

You had problems in a previous pregnancy, such as a baby who died at birth.

You have noticed that your baby is moving less.

You are past your due date.

You have a disease, such as diabetes. 



Several nonstress tests may need to be done to show the baby's well-being over time.
