Details about Presentation scan (36-40 weeks)
What is a Presentation Scan (36–40 Weeks)?
A Presentation Scan is a third-trimester pregnancy ultrasound carried out in the final weeks of pregnancy to determine how your baby is positioned in the uterus as birth approaches.
The scan confirms whether the baby is head-down (cephalic), breech, transverse, or oblique, and assesses factors that may influence delivery planning. It also reviews placental position, amniotic fluid volume, and fetal heartbeat, providing reassurance about late-pregnancy wellbeing.
This scan is commonly used to support birth planning, especially when baby’s position is uncertain or has previously been non-head-down.
When a Presentation Scan is recommended
A Presentation Scan is typically recommended in the final weeks of pregnancy.
You may be advised to have this scan if you:
- Are approaching your due date
- Want confirmation of baby’s position
- Have had a breech or transverse position earlier
- Have not had recent ultrasound assessment
- Are planning mode of delivery
- Have reduced or changed fetal movements
- Have had previous pregnancy or delivery complications
- Want reassurance before labour begins
What the Presentation Scan assesses
The scan focuses on:
- Baby’s presentation (head-down, breech, transverse)
- Baby’s position within the uterus
- Fetal heartbeat
- Placental location
- Amniotic fluid volume
- General late-pregnancy wellbeing
This scan is not intended to replace earlier growth or anomaly scans, but to provide targeted information close to delivery.

- Cephalic presentation confirmed
Breech or transverse position
The baby is positioned bottom-first or sideways.
Typical report:
- Breech / transverse presentation noted
Further discussion or follow-up may be advised.

Typical report:
- Placental position and fluid within expected range
Results are explained in context of gestational age and birth planning.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
