Alongside your dating scan, the NHS offers combined screening for Down's syndrome (Trisomy 21), Edwards' syndrome (Trisomy 18) and Patau's syndrome (Trisomy 13).
Screening doesn't diagnose anything. It gives you a chance — a likelihood — which can help you decide whether you'd like further testing. Taking part is completely your choice.
🔍What it checks
- A nuchal translucency (NT) measurement taken during the scan
- A blood test from you
- Your age and other factors, combined into a chance result
💛What to expect
If screening shows a higher chance, you'll be offered further options, which may include NIPT (a more detailed blood test) or diagnostic tests such as CVS or amniocentesis.
There's no right or wrong decision. Some parents want as much information as possible; others prefer not to screen. Your midwife will support whatever feels right for you.
💬Questions worth asking
- What does a 'higher chance' result actually mean?
- What are my options if the result is higher chance?
- Is NIPT available to me, and how does it differ?
Good to know. This is general information about screening choices, not advice on what to decide. Your midwife or screening team is there to help you weigh it up.
