1:8 risk of Down's but Harmony test was fine - ?

[thayet]

Just wondering if anyone has had any experience with this..

On the 12 week ultrasound, the baby's NT measurement was 3.1mm. I panicked and opted for the non-invasive Harmony test (also called MaterniT21 in the US) and the results came back clear (ie. no probable trisomies detected). Now I just got the results back from my integrated prenatal screen and was given a 1:8 risk of Down's.

Has anyone had as high a risk as 1:8 and had a healthy baby? There were no other soft markers for genetic abnormalities on the ultrasound, as far as I know. I have an appointment with a genetics counselor tomorrow. Thanks.

If the results came back clear on the Harmony test, it means your baby does NOT have Down Syndrome (unless I'm missing something???). My understanding is that the prenatal screen (blood work + nuchal fold measurement + mother's age) only generates your RISK for certain conditions; while the Harmony test tells you CONCLUSIVELY whether or not the baby has them. So - again, unless I'm missing something?? - your baby is fine!

Also, the vast majority of women who get 1:8 risk of Down Syndrome will have babies that DO NOT have the condition. You can kind of imagine risk of 1:8 like this: There are 8 women, all of whom get results of 1:8 risk for Down Syndrome; ultimately, 7 women have babies WITHOUT Down Syndrome, and only 1 woman has a baby with Down Syndrome.

Good luck today! I hope I didn't misunderstand and that everything is, in fact, perfect!!
