Nuchal Translucency – This is an optional test that consists of a blood test and an ultrasound that are performed between 11 and 14 weeks to check the risk of Down Syndrome and two other chromosomal conditions (Trisomy 13 and Trisomy 18). This is used as a screening tool, and the results cannot confirm the presence or absence of any of these conditions. If a couple wished to know for certain, then they have the option of undergoing an amniocentesis or chorionic villus sampling (see below). We will discuss this and the implications of all of this at your appointment to help you make your own choice of whether to have this test or not.
Foetal Anomaly or Morphology Ultrasound – This ultrasound is performed between 18 and 20 weeks and involves a detailed assessment of your baby to check for normal development. Although it is not possible to identify all abnormalities, over 50% of major abnormalities can be identified with this ultrasound. You will also have the opportunity to find out the sex of your baby during this ultrasound.
Other Ultrasounds – There may be reasons for your pregnancy to be high risk. If this is the case then you might require further ultrasounds during your pregnancy.
