Non-Stress Testing

What is Non-Stress Testing (NST)?

Non-Stress Testing or NST, is a non-invasive procedure used to monitor the heart rate of the fetus. It evaluates the baby’s heart rate in response to its movements, providing information about the baby’s well-being. This test is often recommended when a healthcare provider wants to assess the health of the fetus in cases where there may be concerns regarding growth, gestational age, or potential complications.

Non-Stress Testing

Purpose of NST

The purpose of Non-Stress Testing is to assess the fetal heart rate in response to fetal movements. This helps healthcare providers evaluate the baby’s well-being and identify any signs of fetal distress or compromised oxygenation. It is often used to monitor the health of the fetus during high-risk pregnancies or when there are concerns about fetal growth or development.

Who needs NST?

Non-Stress Testing may be recommended for various reasons, including:

  • High-risk pregnancies: For mothers with certain medical conditions such as diabetes, hypertension, or kidney disease, an NST helps monitor fetal well-being.
  • Post-dates pregnancy: If a pregnancy goes beyond the expected due date, NST can be used to evaluate fetal health.
  • Growth concerns: If there are concerns regarding the fetus’s growth or weight, an NST can provide additional insights into the baby’s well-being.
  • Complications or Abnormalities: Pregnancies that involve complications like placental insufficiency or fetal growth restriction may warrant an NST for closer monitoring.
  • Certain medical conditions: Mothers with conditions like preeclampsia or gestational diabetes may have an NST as part of their routine prenatal care.

Benefits of NST

  • Early detection of fetal distress: NST provides valuable insights into the baby’s well-being and allows for early detection of potential issues such as fetal distress, which can prompt timely intervention if necessary.
  • Non-invasive: Unlike other tests, NST is non-invasive and poses minimal risk to both the mother and the fetus.
  • Informed decision making: The test helps healthcare providers make informed decisions about labor and delivery, ensuring the safest possible environment for childbirth.

How NST is Conducted?

During an NST, you will be asked to lie down in a comfortable position. A healthcare provider will attach two straps to your abdomen using elastic belts. One strap monitors the fetal heart rate, and the other records uterine contractions. The test typically lasts between 20 to 30 minutes.

Preparation for the Test

  • Clothing and Hygiene: Wear loose, comfortable clothing. Avoid using lotions or creams on your abdomen as they may interfere with the fetal monitoring equipment.
  • Dietary Restrictions: Eat normally and hydrate well before the test. A well-fed and hydrated fetus is more active, which can give better results during the test.
  • Scheduling: Schedule the test in advance by contacting Shukan Hospital & IVF Centre. If you have a referral, you can coordinate with our medical team to arrange the test at a convenient time.

Results Interpretation

  • Normal Results: A normal NST result shows fetal heart rate variability in response to fetal movements, which typically indicates a healthy, well-oxygenated fetus.
  • Abnormal Results: An abnormal NST result might suggest a need for further assessment or intervention. This could involve additional tests or monitoring to ensure the baby’s health.

What is a normal NST value?

A normal NST result typically shows a baseline fetal heart rate of 110 to 160 beats per minute. The test will also demonstrate variability in the fetal heart rate, meaning the heart rate fluctuates within a range. Additionally, the fetal heart rate should accelerate with fetal movements, indicating a responsive and healthy baby.

Is the test painful?

No, NST is painless and non-invasive.

Can I eat or drink before the test?

Yes, you can eat and drink normally before the test.

What happens if the test results are abnormal?

An abnormal result may prompt further monitoring or intervention, such as additional tests or medical evaluation.

How often should I undergo an NST during my pregnancy?

The frequency of NSTs can vary based on your pregnancy’s specific circumstances and your healthcare provider’s recommendations. It’s best to consult with your healthcare provider to determine a suitable schedule.

What if my baby doesn’t move during the NST?

Movement of the fetus can vary, and sometimes babies are more active at different times of the day. If the baby is not as active, the healthcare provider may have you reposition or wait for a short period to allow the baby to move.

Is there any risk associated with an NST?

NST is a safe and non-invasive procedure. There are no known risks to the mother or fetus. It poses minimal risk, and there are no side effects associated with the test.

Can I continue my daily activities before the test?

Yes, you can carry out your regular daily activities before the test. Just make sure you have eaten and are well-hydrated before the test for optimal results.

What happens if the NST results are inconclusive?

If the NST results are inconclusive, your healthcare provider may recommend additional monitoring, such as a more extended NST or other tests, to gather more information about the baby’s well-being.

How long does it take to receive the results?

The results of an NST test are usually interpreted immediately. Your healthcare provider will discuss the results with you and, if needed, suggest further actions or interventions.

Can I drive home after the NST test?

Yes, you can drive yourself home after the NST test unless advised otherwise by your healthcare provider. The test is non-invasive and poses no restrictions on your ability to perform daily activities.

What if I have a high-risk pregnancy?

If you have a high-risk pregnancy, your healthcare provider may recommend more frequent NSTs to monitor fetal well-being and adjust care as needed.

How does an NST differ from other fetal monitoring tests like a biophysical profile (BPP)?

An NST primarily monitors the fetal heart rate in response to movements, whereas a biophysical profile (BPP) provides a more comprehensive assessment of fetal health, including movement, muscle tone, breathing, and amniotic fluid levels. Your healthcare provider may recommend one or both tests based on your pregnancy’s needs.

Can I take a shower or bath before the NST test?

Yes, you can take a shower or bath before the NST test. Just make sure to avoid using lotions or creams on your abdomen, as they can interfere with the monitoring equipment.

What if my baby is asleep during the NST?

If the baby is asleep during the NST, the healthcare provider may ask you to change positions, move around, or drink some cold water to encourage fetal movement.

Can NST be performed more than once during a pregnancy?

Yes, NST can be performed more than once during a pregnancy, especially if there are concerns about fetal well-being or high-risk factors.

Is there anything that can affect the accuracy of the NST test?

Factors such as maternal movement, fetal sleep cycles, or maternal position changes can potentially affect the accuracy of the test. Healthcare providers take these variables into account when interpreting the results.

Is NST suitable for all pregnancies?

NST is generally safe and suitable for most pregnancies. However, certain high-risk pregnancies or specific medical conditions may require additional monitoring or alternative testing. Your healthcare provider will determine the best approach for you.

Can I have an NST if I am on bed rest?

Yes, you can have an NST while on bed rest. Your healthcare provider may adjust the testing process or schedule to accommodate your condition.
