It is reported as a "1 in so many" chance of the baby having Down syndrome. for example 1 in 10 or 1 in 5000 or anywhere along the way. It just says there is a low risk or a high risk of it. It never says the baby has it and it never says the baby doesn't have it. An echogenic cardiac focus(If I remember correctly) means somewhere in the 1-3 % range for the baby having it, regardless of what the Triple screen shows.
