Overview of the Growth and Wellbeing – Advance (24–36 weeks)
The Growth and Wellbeing – Advance scan is a later-pregnancy ultrasound performed between 24 and 36 weeks to assess fetal growth and selected features of pregnancy wellbeing.
The examination uses fetal measurements to estimate size and growth.
Common measurements include the baby's head, abdomen and femur.
These can be combined to calculate an estimated fetal weight.
The scan also assesses fetal position, visible movement, amniotic fluid and placental location.
Depending on the precise advanced scan protocol and clinical indication, selected Doppler blood-flow measurements may also be included.
Growth ultrasound is particularly useful when there is concern that a baby may be measuring smaller or larger than expected, when previous growth requires monitoring or when additional third-trimester assessment has been recommended.
One growth measurement provides a snapshot.
Serial scans are often more informative for assessing growth trajectory, because they show how measurements change over time.
This service is provided as a home visit only.
What Does the Growth and Wellbeing – Advance (24–36 weeks) Assess?
Head measurements - Assesses fetal head size using standard biometric measurements.
Abdominal circumference - Provides an important measurement used when assessing fetal growth.
Femur length - Measures a long bone and contributes to growth assessment.
Estimated fetal weight - Combines measurements to estimate fetal weight.
Fetal heartbeat - Confirms cardiac activity.
Fetal movement - Visible movement can be observed during the scan.
Fetal position - Documents whether the baby is cephalic, breech, transverse or in another position at the time of scanning.
Placental position - Documents the location of the placenta.
Amniotic fluid - Assesses whether the visible fluid volume appears appropriate.
Doppler assessment where included - Selected blood-flow measurements may be performed according to the booked advanced protocol.
Who May Benefit From the Growth and Wellbeing – Advance (24–36 weeks)?
People whose baby is measuring small or large for gestational age - Ultrasound provides objective fetal measurements.
People requiring additional growth monitoring - Serial measurements can demonstrate a growth pattern.
People with previous pregnancy growth concerns - Additional surveillance may be appropriate.
People wanting third-trimester fetal growth assessment - The scan provides a current size and wellbeing snapshot.
People with maternal conditions affecting pregnancy growth - Additional ultrasound can sometimes be recommended as part of maternity care.
People requiring assessment of fetal position, placenta or fluid - These can be reviewed during the scan.
Symptoms and Reasons to Consider the Growth and Wellbeing – Advance (24–36 weeks)
This scan is generally used for planned monitoring rather than emergency symptom assessment.
Fundal-height measurements smaller than expected - Ultrasound can assess fetal biometry.
Fundal-height measurements larger than expected - Estimated fetal weight and fluid can provide additional information.
Previous growth-scan abnormality - Repeat measurement can assess interval growth.
A pregnancy requiring additional surveillance - Growth ultrasound can provide complementary information.
Uncertainty about fetal position - The baby's presentation can be documented.
Need to reassess placental position - Placental location can be reviewed.
A noticeable reduction or change in your baby's usual movements requires immediate contact with your maternity unit.
Do not wait for a private home growth scan to investigate reduced fetal movements.
How to Prepare for the Growth and Wellbeing – Advance (24–36 weeks)
Estimated fetal weight is an ultrasound calculation rather than an exact measurement and has a recognised margin of error.
Serial measurements should be interpreted alongside your wider maternity assessment.
What Happens During the Growth and Wellbeing – Advance (24–36 weeks)?
Is the Growth and Wellbeing – Advance (24–36 weeks) Safe?
The scan uses diagnostic ultrasound.
No ionising radiation is used.

Understanding Your Growth and Wellbeing – Advance (24–36 weeks) Results
The report may provide fetal measurements and an estimated fetal weight plotted against gestational age.
A baby can measure above or below average and still be healthy.
What matters clinically is the degree of difference, the pattern over time and associated pregnancy findings.
Unexpectedly low growth, excessive growth, altered fluid or abnormal Doppler findings can require additional surveillance.
Ultrasound-estimated fetal weight is not exact and should be interpreted within its known measurement limitations.
What Can the Growth and Wellbeing – Advance (24–36 weeks) Detect?
Fetal growth differences - Measurements can identify a baby measuring smaller or larger than expected.
Changes in growth trajectory - Serial scans can identify slowing or acceleration of growth.
Abnormal amniotic-fluid volume - Reduced or increased fluid can be detected.
Fetal presentation - Breech, cephalic or transverse position can be documented.
Placental position - The location of the placenta can be reassessed.
Selected blood-flow abnormalities - Doppler can provide additional information where included.
Limitations of the Growth and Wellbeing – Advance (24–36 weeks)
Estimated fetal weight is not exact - Ultrasound calculations have a recognised margin of error.
One scan cannot establish growth velocity - Comparison with previous measurements is more informative.
Not all fetal conditions are detectable - Growth assessment is not a substitute for anomaly screening.
Fetal position can affect measurement quality - Some views can be difficult.
The scan does not replace maternity surveillance - Clinical monitoring remains essential.
