1:1700 result of downs screening

[Royalsighness]

My first was 1 in 8,000 and this one is 1 in 1700 what does it mean? I can't find any clear iformation online about it.

[ProbablyMe]

It means you have a tiny risk of your baby having Downs Syndrome - about 0.6%. It's determined by your unchallenged translucency measurement, combined blood test and age.

[ProbablyMe]

Sorry - 0.06%

My first pregnany was 1 in 8000 and second 1 in 150. Both were fine. I think its just statistics. You have a slightly higher chance this time but still a very low chance. My second pregnancy had a much thicker nuchal translucency. I dont why though.

[Greencurtain]

It's very low anyway. It's probable the increased risk (although still tiny) is due to your increased age this time around. I didn't get any info for my dc2 so can't compare dc1 and dc2.

[Royalsighness]

I am 23 an the fluid on the neck measured 1.4mm and from what I've read my age and this measurement should make me low risk so why is it so high?

[Royalsighness]

I know it's not high, I just wonder wether it's worth worrying about?

[HaveYouTriedARewardChart]

Probably your blood hormone levels (if you had blood tests too) It's a very small risk though.

[PacificDogwood]

It means if you had 1700 babies, 1699 of them would be healthy and one would have Down's.

1 in whatever only every gives your a risk - you can have a high risk of something and it does not happen, or a low risk and it does happen.

I'd not worry about 1 in 1700.

I did worry about mine at 1:16 for Down's and 1:4 for Patau's and had 4 healthy children.

V best of luck.

[HaveYouTriedARewardChart]

It's based on an algorithm by the way, age, nuchal measurement and blood hormone levels all go in to the calculation. There's no need to worry that it means anything unusual.

[tumbletumble]

As others have said, the increase is probably due to your age. My DC's rates varied from 1 in 50,000 to 1 in 250. I had an amnio for the latter, but I wouldn't for 1 in 1700.

[Slongette]

My DS1 was 1:6500

I've just had my quad results back for DC2 and I got a 1:25 chance of downs.

I chose to have an amnio and it's come back clear. If I'd had a 1:1700 I would not have worried at all and certainly not had the amnio.

Thankyou, it's starting to make more sense now and I feel a lot better
