The maternity stress test, also known as the non-stress test (NST) or biophysical profile (BPP), is a common prenatal assessment used to evaluate the well-being of a fetus during pregnancy. This test is usually performed in the third trimester, around 28-40 weeks of gestation, and is a crucial tool for healthcare providers to monitor fetal health and detect potential complications. As an expecting mother, it's essential to understand what to expect during this test and how it can impact your pregnancy.
The primary goal of the maternity stress test is to assess the fetus's vital signs, movement, and overall health. The test is typically recommended for women with high-risk pregnancies, such as those with a history of gestational diabetes, hypertension, or previous fetal complications. However, it may also be performed on low-risk pregnancies as a precautionary measure.
What Happens During the Maternity Stress Test?
During the test, you'll be asked to lie down on a comfortable bed or table, and a fetal heart rate monitor will be placed on your abdomen. This monitor measures the fetus's heart rate and detects any changes in response to movement. You may be asked to perform certain activities, such as drinking water or eating a snack, to stimulate fetal movement.
The test typically lasts for 20-40 minutes, during which time you'll be asked to report any fetal movements you feel. The healthcare provider will also use an ultrasound machine to evaluate the fetus's movement, tone, and breathing. The test is usually performed in a quiet and comfortable environment, and you may be accompanied by a partner or support person.
Types of Maternity Stress Tests
There are two primary types of maternity stress tests: the non-stress test (NST) and the biophysical profile (BPP).
- Non-Stress Test (NST): This test measures the fetus’s heart rate in response to movement. A reactive result indicates a healthy fetus, while a non-reactive result may require further testing.
- Biophysical Profile (BPP): This test combines the NST with an ultrasound evaluation of the fetus’s movement, tone, and breathing. A score of 8-10 indicates a healthy fetus, while a lower score may indicate potential complications.

| NST | Fetal heart rate monitoring | 20-30 minutes |
| BPP | Combination of NST and ultrasound evaluation | 30-40 minutes |
Key Points
Interpreting the Results
The results of the maternity stress test will be interpreted by your healthcare provider, and the findings will be discussed with you. A reactive or normal result indicates a healthy fetus, while a non-reactive or abnormal result may require further testing or intervention.
In some cases, a non-reactive result may be a false negative, and your healthcare provider may recommend a repeat test or additional assessments. It's essential to discuss any concerns or questions you have with your healthcare provider to ensure you understand the results and any necessary next steps.
What to Expect After the Test
After the test, you'll be able to resume your normal activities. Your healthcare provider will discuss the results with you and provide guidance on any necessary follow-up care.
In some cases, additional testing or monitoring may be required to ensure the health and well-being of you and your fetus. Your healthcare provider will work with you to develop a plan for ongoing care and monitoring.
