Wellbeing Scan

What Is a Wellbeing Scan?

During this scan, the baby is measured to estimate fetal weight, amniotic fluid, and fetal movement are assessed, and color doppler examination of blood flow to the placenta and fetus may be measured.

When Can I Have the Wellbeing Scan?

The Wellbeing scan or Growth Scan is usually performed around 32 weeks of pregnancy although it can be performed from 26 weeks of pregnancy up to term.

Why Should I Have a Wellbeing Scan?

We believe that all women should have this scan to see if the baby is growing at a normal rate with no complications.

What Does the Wellbeing Scan Check For?

This scan aims to determine the growth and health of the fetus by:

• Measurement of the size of the fetal head (HC), abdomen (AC), and femur (FL) 
• The HC, AC, and FL measurements are then used to calculate an estimate of the baby’s fetal weight (EFW). This is best predicted from 28 weeks onwards 
• Examination of the movements of the fetus 
• Evaluation of the placental position and appearance 
• Measurement of the amount of amniotic fluid 
• Assessment of placenta position and blood flow to the placenta and fetus by color Doppler ultrasound

What Is the Next Step I Should Have After the Wellbeing Scan?

Further wellbeing scans can be performed anytime for reassurance or if concerns remain. When serial Wellbeing scans are recommended then these should be performed at the time intervals recommended by the doctor. Usually, this time interval is 2-4 weeks.
