Non-invasive Down’s test to be rolled out
A MORE accurate test for Down’s syndrome that allows pregnant women to be screened without the risk of miscarriage is to be introduced in Wales.
Public Health Minister Rebecca Evans has confirmed that the Welsh Government has agreed to the introduction of non-invasive prenatal testing (NIPT) within the antenatal screening programme in Wales.
When women are between 11 and 14 weeks’ pregnant, an ultrasound scan is typically offered as an initial test for Down’s syndrome.
It measures nuchal translucency (a pocket of fluid) at the back of the baby’s neck. If the risk is high – usually above one in 150 – women are offered an invasive diagnostic test known as amniocentesis to confirm the diagnosis.
The test, which carries a small risk of miscarriage, involves a fine needle being passed through the wall of the abdomen and uterus into the amniotic fluid that surrounds the baby inside the womb.
Now the Welsh Government says NIPT, a blood sample analysed in a laboratory, will be added to the screening pathway. It will be offered as an additional option to these invasive tests and for women who receive a negative result no further tests will be required.
Public Health Minister Rebecca Evans said: “We want to ensure every expectant mother in Wales receives the information, advice and support they need throughout their pregnancy.
“Our antenatal screening programme plays an important role in this.”
