Pregnancy Guide

Screening for Down’s syndrome, Edwards’ syndrome and Patau’s syndrome

All pregnant women in Wales are offered a screening test for Down's syndrome, Edwards' syndrome and Patau's syndrome between 10 and 14 weeks of pregnancy. This is to assess your chances of having a baby with these conditions.

Down's syndrome is also called trisomy 21 or T21. Edwards' syndrome is also called trisomy 18 or T18, and Patau's syndrome is also called trisomy 13 or T13.

If a screening test shows that you have a higher chance of having a baby with Down's syndrome, Edwards' syndrome or Patau's syndrome, you'll be offered diagnostic tests to find out for certain if your baby has the condition.

You are advised to watch a film clip before you see your midwife for the first time. The film clip, which gives you more information about screening for these syndromes, is available from:  http://www.antenatalscreening.wales.nhs.uk/public/home
