Non-Stress Test (NST)
About Non-Stress Test (NST)
Non-Stress Test (NST) is a non-invasive prenatal test used to monitor fetal heart rate and its response to movements.
It helps assess the well-being of the fetus, especially in high-risk pregnancies. The test measures whether the baby’s heart rate increases appropriately with movement, indicating adequate oxygen supply.
Overview
Evaluates fetal health and oxygenation
Monitors fetal heart rate in response to movements
Used in high-risk pregnancies (diabetes, hypertension, etc.)
Helps detect fetal distress or compromised conditions
Often performed in late pregnancy or when reduced fetal movements are noted
Workflow
- Step 1: Patient Preparation Mother is positioned comfortably, usually in a semi-reclining position.
- Step 2: Sensor Placement Two belts are placed on the abdomen—one for fetal heart rate and one for uterine activity.
- Step 3: Monitoring Fetal heart rate and movements are recorded over time.
- Step 4: Data Recording Graph (CTG tracing) is generated showing heart rate patterns.
- Step 5: Interpretation Doctor evaluates reactivity and variability of fetal heart rate.
- Step 6: Reporting Results are documented and explained to the patient.

How is a Non-Stress Test performed at Nano Hospitals? +
Sensors are placed on the mother's abdomen to monitor the baby's heart rate and uterine activity while the baby is being observed for movements.
Is a Non-Stress Test safe for the baby? +

Is an NST painful? +
No. An NST is generally painless. The sensors are placed externally on the mother's abdomen during the test.
How long does a Non-Stress Test take? +
An NST generally takes around 20–40 minutes, although the duration may vary depending on the baby's activity and the doctor's assessment.
Do I need to prepare before an NST at Nano Hospitals? +
Usually, no special preparation is required. Your doctor or the Nano Hospitals maternity team may provide specific instructions based on your pregnancy.
What does an NST result indicate? +
The test helps the doctor assess the baby's heart rate pattern and response to movement and determine whether additional monitoring or evaluation may be needed.
