About The Test
Purpose of the Scan
The Pregnancy Interval Growth Scan with BPP & Doppler Ultrasound Scan is a specialised third-trimester ultrasound that tracks your baby’s growth velocity, checks the placenta’s efficiency, and evaluates blood flow to and from the baby.
Key Benefits for Mother and Baby
- Confirms adequate fetal oxygenation and nutrient supply
- Detects early signs of growth restriction or placental insufficiency
- Guides timely medical intervention to lower stillbirth risk
- Provides reassurance to expectant parents with detailed visual feedback
What Is Pregnancy Interval Growth Scan with BPP & Doppler Ultrasound Scan?
Understanding the Biophysical Profile (BPP)
The Biophysical Profile is a 30-minute, non-invasive test that scores five vital fetal behaviours:
| Parameter | Points | Normal Range |
|---|---|---|
| Breathing movements | 0–2 | ≥1 episode ≥30 sec |
| Gross body movements | 0–2 | ≥3 discrete movements |
| Fetal tone | 0–2 | ≥1 extension-flexion |
| Amniotic fluid index (AFI) | 0–2 | ≥8 cm |
| Non-stress test (NST)* | 0–2 | Reactive |
*Added if clinically required.
Role of Doppler Ultrasound in Pregnancy
Doppler measures blood-flow velocity in the umbilical artery and, when needed, the middle cerebral artery (MCA). This reveals whether the baby is compensating for reduced placental function by redistributing blood flow.
Difference Between Routine Growth Scan and BPP+Doppler
- Routine growth scan: Assesses size, weight, and amniotic fluid only.
- Pregnancy interval growth scan with BPP & Doppler ultrasound scan: Adds functional evaluation of placental efficiency and fetal oxygenation.
Types of Scans Available at Cadabams Diagnostics
| Type | Technology Highlights | When to Choose |
|---|---|---|
| Standard 2D BPP & Doppler | Reliable, quick, insurance-covered | Routine care |

| *Optional add-on, additional charge applies. |
List of Parameters
- Fetal breathing movements
- Gross body movements
- Fetal tone
- Amniotic Fluid Index (AFI)
- Umbilical Artery Doppler
- Middle Cerebral Artery Doppler (if clinically indicated)
Why This Test
- Monitor fetal growth velocity
- Evaluate placental function
- Assess fetal oxygenation status
When to Take Test
Recommended Gestational Weeks
- 28–40 weeks: Standard interval scan every 3–4 weeks.
- Weekly or bi-weekly: If intrauterine growth restriction (IUGR) or placental issues are suspected.
High-Risk Pregnancy Indicators
- Diabetes, hypertension, or pre-eclampsia
- Previous IUGR or stillbirth
- Decreased fetal movements
- Abnormal fundal height curve
- Twin or multiple pregnancy
Doctor Referral Criteria
Any consultant obstetrician or gynaecologist can refer. Bring your pregnancy notes and any previous scan reports.
Benefits
Benefits of Taking the Scan
- Early detection of IUGR
- Timely intervention (e.g., delivery planning, steroid administration)
- Reassurance when results are normal
Illnesses Diagnosed
| Illness/Observation | Significance |
|---|---|
| Intrauterine Growth Restriction (IUGR) | Fails to meet growth potential |
| Placental insufficiency | Inadequate nutrient/oxygen transfer |
| Oligohydramnios / Polyhydramnios | Abnormal fluid volume |
| Abnormal fetal blood flow | Indicates fetal compromise |
Preparing for test
- Wear loose clothing for easy abdominal access.
- Bring prior scan reports for comparison.
- Have a light snack or juice 20 min before to encourage fetal activity.
Prerequisites
- Signed referral from your obstetrician
- Valid pregnancy notes or maternity booklet
Best Time to Schedule
- Optimal: 28–36 weeks for interval growth pattern.
- Follow-up: Weekly or bi-weekly if IUGR suspected.
Eligibility
- All pregnant women ≥28 weeks gestation
- Especially recommended for high-risk pregnancies
Step-by-Step Procedure
- Check-in & ID verification at Cadabams Diagnostics reception
- Ultrasound gel applied to abdomen
- BPP scoring over ~30 minutes
- Doppler measurements (umbilical & MCA) in 10–15 minutes
- Report printed and explained by the sonographer; digital copy sent via email/SMS
Caution Before the Scan
- Inform your sonographer of latex allergy
- Report any vaginal bleeding or ruptured membranes
Test Results
Results and Interpretations
| Finding / Observation | Description | General Interpretation / Significance |
|---|---|---|
| BPP Score 8–10 | All parameters normal | Reassuring fetal well-being |
| BPP Score 6 | One parameter borderline | Repeat within 24 hours or deliver if ≥37 weeks |
| Umbilical artery PI >95th centile | High resistance | Possible placental insufficiency |
| MCA PI <5th centile | Brain-sparing effect | Sign of fetal compromise |
| AFI <5 cm | Oligohydramnios | Consider further investigation or delivery |
Risks & Limitations
- Safety: Ultrasound uses no radiation; hundred-thousand-plus scans show no harmful effects.
- Limitations:
- Maternal obesity may reduce image clarity.
- Severe oligohydramnios can obscure some views.
FAQs
How long does the scan take?
~45 minutes including report discussion.
Is fasting required
No, eat normally; a light snack helps fetal activity.
When will I get the report?
Immediately after the scan; digital copy also available.
Can I bring a companion?
Yes, one adult family member is welcome.
Does insurance cover the scan
Most maternity packages include this test—verify at Cadabams front desk.
