It is usually part of an assessment called combined first trimester screening.

Combined first trimester screening assesses the risk for your baby having certain chromosomal abnormalities (trisomy 13, 18 and 21).

As time has gone on, the ultrasound equipment and our ability to interpret the images have both improved.

This testing combines the nuchal translucency ultrasound with specific blood tests.

Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening.

Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis.

This means that combined first trimester screening simply tells us if your risk is low or high.
