Obstetrics: Non Stress Test

A NST is a procedure that is performed to measure fetal well-being.

This is done by monitoring fetal heart tones and contractions. Increases in the fetal rates are reassuring of well-being; and the test is then considered reactive. This test lasts approximately 30-60 minutes depending upon your baby’s activity and the number of fetuses that you are carrying.

It is important to eat a light meal 30 minutes prior to your test, and to bring a healthy snack with you to your appointment. This will increase fetal movement.
