Non-invasive prenatal testing (NIPT)- The test analyses cell free fetal/ placental DNA in the mother’s blood, suggesting strongly whether the baby is at high or low chance of having trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome) or trisomy 13 (Patau syndrome).

- The test identifies 99%, but not all, of the babies with trisomy 21, 98% of babies with trisomy 18 and 90% of babies with trisomy 13.
- If you decide to have the test you will be asked to sign a consent form by one of our doctors or an appropriately trained member of our staff. We will then draw a small amount of blood from a vein in your arm and sample is sent to the lab for testing. The usual reporting time is 10 working days
