Ultrasound is used to take a measurement of a particular skin fold at the back of your baby’s neck.
In babies with Downs syndrome, this fold of skin is thicker than in babies without the syndrome.
Although the baby’s sex can often be determined during this study, this is dependent on the baby’s position at the time of the examination and is not always possible.
Please drink 500ml of water and hold for one hour prior to your appointment.
You will receive paperwork by email or post prior to your appointment.
Once the relevant skin fold has been detected, measurements will be taken on screen, then printed out as a graph to determine the risk factor for your obstetrician/general practitioner to consider.
A Nuchal Translucency (NT) assessment is used to indicate whether a baby has a low or high risk of a chromosomal abnormality.
This is a screening test which helps provide an early indicator to your doctor.
This measurement is used, along with the results of blood tests, to calculate the your babies risk factor.
You should arrive 10 minutes before your appointment time to complete all necessary paperwork.
