Please discuss the tests and ask any questions that you have with your maternity team.

The main screening tests that we will offer you during your pregnancy are listed below: Back to top You will be offered a scan to accurately determine when your baby is due.

If your pregnancy is too far advanced for combined screening or we are unable to measure the nuchal translucency due to the baby’s position at the time of the scan or your increased body mass index (BMI), you will be offered the quadruple test.

This involves taking a blood sample from you, measuring four hormones and combining these with your age and other factors to estimate the risk of you having a baby affected with Down’s syndrome.

The crown-rump length (CRL) of the baby is measured and your expected date of delivery (EDD) confirmed.

You will also be offered combined screening for Down’s syndrome, which your community midwife will have discussed with you at your booking appointment.

This will help us assess that your baby is growing as he/she should be during your pregnancy and will also help you to plan for the arrival.

Back to top At your dating scan, you will also be offered a nuchal translucency (NT) scan.

If you have other children that you would like to bring into the scan room, please inform the Sonographer.

They should be cared for in the waiting room by a friend/relative and the Sonographer may allow them in at the end of the scan.

This test involves measuring the thickness of the fluid space at the back of the baby’s neck (nuchal translucency) and combining this with a blood sample taken from you, which measures two hormones present at this stage in pregnancy.
