1:26 risk of Downs

[elefantra]

Hi everyone! Last week, I had my NL scan which, combined with the blood work, resulted in a 1:26 risk of our baby having DS (and 1:88 risk of trisomy 13/18). Naturally, we're scared, since we weren't expecting those numbers at all. I'm in my mid-twenties.

The NF was 2,90 which was a bit on the thicker side according to the midwife, and my bloodwork was a bit weird, we didn't get a lot of information on that. After googling frenetically, I found out that the beta-hcg level should be around 1 MoM, which it was - 1,20-something, if I'm not mistaken - but the papp-a levels were really low, like 0.223 or something.

I'm also a carrier of a balanced translocation. It shouldn't affect chromosome 21 (my BT is 5;6) but does anyone know if that could mess up the results, giving a false positive? If it's the bloodwork that is the problem, won't NIPT show the same issue and risk a false positive again?

Sorry for all these questions. I'm terrified of losing this baby since we suffered a loss in August, our first pregnancy, at 18 weeks due to our CVS.

NIPT works by analysing tiny quantities of the baby’s DNA in your blood, the quad test measures hormone levels.

Go for nipt. It’s looking directly at the dna.

NIPT is virtually 100% and without the risk of miscarriage. I hope it give you the reassurance all is well x
