Dating scan pregnancy
The price you’ll pay for non-NHS scans depends on the type of scan you want, how many private scans you have and the area you live in.
A survey we ran in 2019 showed that while 18% of people who had private scans paid less than £50, 10% of parents spent more than £500.
It’s also sometimes referred to as the NT (nuchal translucency) scan.
The test can’t tell for sure whether your baby has Down’s syndrome or another similar condition but can identify whether they’re at risk.
The probe sends out ultrasound waves – sound waves with a frequency higher than the human ear is able to hear – to produce images of your baby, which the sonographer studies on a screen.
Ultrasound scans in pregnancy have several purposes: Ultrasound scans have been used for many years, and there are no known risks to you or your baby from having the routine scans offered in pregnancy.
The best time to do a 3D or 4D scan is usually towards the end of your second trimester or at start of your third trimester (around 26-32 weeks).
Before 26 weeks your baby hasn’t put on a lot of fat and so will look very skinny and the bones of the face will show through, and after around 32 weeks your baby is more squeezed up and running out of space, so it’s harder to get clear pictures.
Feeling anxious about your baby is quite natural during the early stages of your pregnancy and if you have any concerns you should consult your midwife first.It takes up to two weeks to get the results, but you should be told within three working days if your baby is at high risk.Based on the result, you might choose to have further tests to get a definitive answer.If you’d rather not know about possible risks, you can have the dating scan without the combined test. Between 18 and 21 weeks, you’ll have your anomaly scan, which is sometimes called the mid-pregnancy scan.The sonographer will take a detailed look at your baby’s heart, brain, bones, spinal cord, face, kidneys and abdomen to check for a range of conditions.
