Regardless of your prenatal genetic screening decisions, you would be offered a detailed anatomy ultrasound. The ultrasound is ideally done between 18 and 22 weeks' gestation and will look at the growth and structural development of the baby (e.g. checking the structure of the baby's heart). The ultrasound can be done past this time window. However, all of the different parts of the baby may become more difficult to examine as the baby grows.
