If you're pregnant and you've recently booked a reassurance scan, you may well be wondering what to expect on the day. Conversely, perhaps you're still trying to decide what kind of ultrasound package is right for you, in which case you may wish to learn more about the reassurance scan and what this option has to offer. Either way, the First Encounters team are here to help!

One important thing to bear in mind is that a reassurance scan is not a substitute for the standard 20 week anomaly scan that's offered by the NHS. Instead, your reassurance scan will complement the results of the NHS appointment, giving you more information and further reassurance that your baby is developing normally without aiming to reach the same level of diagnostic detail.

The main aim of a reassurance scan is to check on the progression of your pregnancy and identify the general health, growth, and wellbeing of your unborn baby. It can be carried out at any point during your pregnancy starting from 14 weeks gestation.

Your reassurance scan will reveal the following information:

  • Growth measurements (including head circumference, abdominal circumference, and femur length). This information allows us to plot your baby's growth onto our average growth chart, which will tell us if your baby is developing faster or slower than average. Our ultrasound machine can also use these measurements to calculate foetal weight.

  • Fluid levels will be observed - these are crucial to the wellbeing of your baby and to the safe progression of your pregnancy, so if we notice that your levels are markedly above or below the set protocol, we will use the four-quadrant technique to collect additional data that will help your NHS doctor to carry out a diagnostic evaluation.

  • An audible heartbeat trace will be carried out during your reassurance scan, allowing you to hear your baby's heartbeat and helping our sonographer to ensure that the foetus is healthy.

  • We will also look to identify the baby's position and the placental site to make sure everything is in the right place.

reAssure™ is our standard 2D reassurance scan here at First Encounters Ultrasound. However, a reassurance scan is included in all of our ultrasound packages (with the exception of pureGender and taster4D™), so the information listed above will almost always be collected as part of your First Encounters experience.
