What is it?
A presentation scan is performed to check on the position of your baby immediately before birth.
Whether you are planning on a natural birth or a caesarean section, the information from the scan is helpful to your midwife or obstetrician in helping to determine the position of your baby and the placenta before delivery and avoiding any complications, such as placenta praevia.
For more information on placenta praevia please see "What is placenta praevia?" in depth link on the left.
What is placenta praevia?
Placenta praevia occurs when the placenta becomes attached to the uterine wall close to or covering the cervix.
It can happen during the first trimester, but usually occurs during the second or third trimester.
Placenta praevia can lead to vaginal bleeding (also known as antepartum haemorrhage) and affects 1 in 200 of all labours.
When should I have a presentation scan?
We recommend that the presentation scan is combined with the Group B Strep (GBS) Screening at 36 weeks.
Combining the two pre-birth services is a convenient way to check on the position of your baby before delivery and to screen for the presence of the GBS bacteria.
If you decide to have a separate presentation scan without the Group B Strep Screening, it can be performed later into your pregnancy.
Your midwife or obstetrician may request a presentation scan once your waters have broken.
What happens during a presentation scan?
During your appointment our sonographer or consultant will:
- Check the amount of fluid around your baby
- Look at the size of your cervix
- Check your baby’s heart rate
- Confirm the position of your baby, placenta and umbilical cord
You will receive a medical report at the end of your appointment. A separate copy will be forwarded to your midwife or obstetrician.
While performing a presentation scan we check the general health of your baby but we do not take detailed measurements at this late stage of pregnancy.
If a more comprehensive fetal check is required we will convert your appointment to a welfare scan, this will calculate the estimated fetal weight of your baby, which will be very close to your baby’s birth weight.
