Increase in down syndrome chance on 12 weeks blood

[EllieJai44]

This is gonna sound silly because I know people have so much higher results/ratio etc but this is 3rd baby for me and previous 2 have been 1 in 10,000 chance for Down syndrome, just got my results through this morning for this baby and the Downs results was 1 in 6,923.

Like I say I know others have way worse results but I'm confused, I'm only a year older than last one, I am slightly heavier but not loads.... I know its low chances but with history of miscarriages and small babies that get delivered early I just didn't need another stress

There's a 99.99% chance your baby DOESN'T have Down's syndrome, that's a really really low chance!

I am not sure how the statistics work but maybe you have gone into a 'new' age category, e.g. turned 35 or 40, and that means that the risk of having a baby with DS is increased.

@FusciasBright21 I know it was more the fact of why it was so different from previous 2, if I was so much older etc I could understand as such!

@RosiePosieDozy I'm only 27 haha thats what confused me!

I have just received my results following a scan and blood work, my NT measurement was considered very low and my chance of downs was 1 in 7000 which I see as absolutely nothing to worry about. Your age and weight will be taken into consideration but if there was any risk as such you would be informed.

They also look at hormones and proteins in the blood test, so there's lots of other variables not just age/weight which are taken into consideration.

That’s a miniscule risk of DS and it’ll be slightly different hormone levels which have changed it this time. It’s also quite a small change from 10,000. Mine doubled in 2 years (but was still low).

My first was 1 In 78,000 my second 1in3600. It didn’t worry me
