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

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

You will always have a choice about whether transvaginal ultrasound is performed.

If you have concerns about transvaginal ultrasound, please discuss this with your sonographer.

The probe is covered with a disposable protective sheath.

A small amount of ultrasound gel is placed on the end of this probe.

A nuchal translucency ultrasound (commonly called a “nuchal scan” or “NT scan”) is an ultrasound performed between 11.5 and 13 weeks 6 days gestation.

Conditions associated with an increased NT measurement include some chromosome abnormalities (for example, trisomy 13, 18 and 21) and some structural problems (for example, heart abnormalities).

This test gives us an indication of whether we should worry about your baby based on these results.

This means that combined first trimester screening will not give us a definitive answer.

Your sonographer will be experienced at performing these ultrasounds during pregnancy. It involves scanning with the ultrasound probe lying in the vagina.

The transvaginal ultrasound probe is thin, about 2cm diameter.

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