T21 risk 1:156, NT 2.8 mm with nasal bone present - waiting for NIPT results
1 in 156 risk for T21 — waiting for NIPT and questioning whether I should have gone straight to invasive testing
Hi everyone, I’m currently waiting for my NIPT results and the anxiety is really getting to me. I’m hoping to hear from anyone who has been in a similar situation.
At my NT ultrasound, baby measured 12w6d. The NT was 2.8 mm, the nasal bone was present, and the basic anatomy they could see at this stage looked normal.
However, my first trimester screening came back with an increased risk for Down syndrome (Trisomy 21) of 1 in 156.
I got somewhat different advice about what to do next.
My family doctor suggested going for invasive diagnostic testing. However, the ultrasound/prenatal screening clinic suggested doing NIPT first, and then considering invasive testing depending on the NIPT result.
I ultimately decided to do the NIPT first. I felt more comfortable following the recommendation from the prenatal screening clinic because they deal with these screenings regularly, whereas I didn't feel very confident in my family doctor's guidance on this particular issue.
Now I'm waiting for the NIPT result and, of course, I'm second-guessing everything and wondering whether I should have just gone straight to CVS/amniocentesis.
Has anyone had similar numbers - particularly an NT around 2.8 mm and a first trimester screening risk around 1 in 156 - and then had a low-risk NIPT?
And for anyone who was given the choice between NIPT first vs. going directly to diagnostic testing, what did you choose and why?
I'm open to hearing both positive and negative experiences. I'm not looking for reassurance only — I'd really like to hear what happened to people with similar results.
