What to Expect at a Non-Stress Test

What is a Non-Stress Test?

A non-stress test measures your babies’ heart rates and records any contractions of your uterus. This test helps gauge your babies’ well being. Normally, a baby’s heart will beat faster (accelerate) when he/she moves. This suggests that the placenta is delivering enough oxygen to your baby’s brain and heart and that baby is doing well.

What’s the procedure like?

Non-stress tests are non-invasive procedures, so there are no needles, IVs, injections, or blood draws. You’ll lie down on a recliner, partially on your side. You may be given a wedge or a couple of rolled up towels to place under your back to allow you to comfortably lean back. Two straps with monitors will be placed around your belly. One monitor measures your baby’s heart rate and the other picks up any contractions. The data is recorded and displayed on a screen.

Under perfect circumstances, a non-stress test should take about 40 minutes from start to finish. Honestly though, I never once left before an hour and most times I was there for 90 minutes. The non-stress test is looking for two heart rate accelerations within 20 minutes. If this is not accomplished within the time frame, you start over. My singleton was not cooperative with this. I can remember, more than once, lying in that chair strapped to a monitor for 2 hours or more. If your baby isn’t participating you might be asked to drink something with a little sugar hoping to get baby moving. If that doesn’t work, the nurse might use a noisemaker to try to wake the baby. This is completely safe for your baby, it will startle him/her, but will not hurt them in any way.

I always made sure to use the restroom before I checked in for my appointment. I would wear my most comfortable clothes, brought books and magazines to read, and of course my smartphone. I also made sure to bring water and a snack, but make sure you sip the water — you don’t want to have a bathroom emergency in the middle of your test. At the facility where I was tested, I was welcome to bring a guest, which helped the time pass quicker, but children under the age of 13 years old were not allowed.

Non-stress tests are usually administered in the hospital, in a multi-station room, so be prepared to share space with other pregnant women. There are curtain dividers, but you are still able to hear what is going on around you. Don’t get discouraged if the women around you are finishing before you. I really believe that babies can feel how we feel; if we are relaxed, they are relaxed, and if we are tense, they will be tense.

What do the results mean?

If your baby has two heart rate accelerations within 20 minutes, your baby is “reactive”, which means your baby has a normal heart rate and is healthy and not under any stress. Yay! Have a great couple of days until your next test.

A “nonreactive” baby is one who does not make a minimum number of movements during the 40-minute period or whose heart doesn’t accelerate as much as expected when they move. This does not necessarily mean your baby is in danger. You will most likely continue testing for an additional 40 minutes. If your practitioner determines that your baby could be under stress, she’ll order further testing. Do not despair! You are performing these tests so that your doctor can best inform you about how to continue to care for your baby or babies.

Scheduling two non-stress tests every week for five weeks straight can be stressful (ironically), especially if you have more little children at home. But once I got some childcare in place for my babies’ older sibling, I really embraced my non-stress tests. It was a little me time, twice a week, where I got to relax in a recliner and read a book or magazine, or waste time on social media for a little while. In a way, it was the perfect way to finish up my pregnancy.
