I’ve just had my results back from my downs/Patau/Edwards screening and although the result is 1 in 6200 for downs and 1 in 1200 for Edwards and Patau’s and I know that these are very low odds but with my DS my results were 1 in 33000 and 1 in 56000 for the same tests. I’m only 28 and my DS isn’t even 2 yet so I can’t see my age having a big effect?! I’m just really shocked by the big difference! Does anyone know what could factor into it? The baby I’m pregnant with now actually had a smaller nuchal fold measurement than my son did!
