OB Third Trimester Ultrasound
An OB third trimester ultrasound evaluates fetal growth, position, and well-being later in pregnancy, when clinically appropriate.
OB ultrasound precaution
Questions about pregnancy viability, miscarriage, or fetal demise require an accompanying quantitative hCG result and close follow-up with an obstetric clinician.
What the exam evaluates
- Fetal growth and estimated weight
- Amniotic fluid
- Position and presentation
Common reasons to request it
- Routine growth and well-being follow-up
- Position or presentation check
- Amniotic fluid check
- Non-urgent reassurance of fetal movement
Approximate duration
Most exams take about 30 to 45 minutes once approved. You can typically return to normal activities immediately afterward.
What to expect
A qualified sonographer or physician applies a warm gel to the skin and moves a small handheld probe over the area. The exam is non-invasive and painless, and you can typically return to normal activities immediately afterward.
How to prepare
When approved
