It’s good to have the test, as it can pick up other issues that can be easily dealt with if you get treatment right away.
for ex, I had low Papp-a during my first pregnancy, normal nuchal and hCG. It have me 1:150 risk for DS but the nipt came back as low.
but this low Papp-a on its own gave me risk of preeclampsia, intrauterine growth restriction, preterm and still birth. I had IUGR ending with static (=no growth) for the last weeks.
I took aspirin from 16 weeks, 75 mg daily. Maybe it help, maybe it could have been worse.
second pregnancy they gave me 150mg daily aspirin from 12 weeks, they said the dose has been updated, and indeed I’ve looked it up myself and this should be the right dose, plus starting it best at 12. If you start after 16 it might not help at all. So hopefully this time around I won’t get any IUGR at all.
other issues could be from increased nuchal measurement, I’ve read it needs more scans to see if it solves by itself, or further tests. It could be even some heart issues, and better to know early and see what they can do.
increased hCG also gives risk of preeclampsia
2nd pregnancy my risk was 1:77, so higher than first, but I’m also older. Nipt again fine.
look up you individual test results as well, flag it with them if any are outside the limits (some will be as that’s why you it the high risk). They should have told you anyway, but some hospitals are not as good as others. I’m in a different town now. With my first I had to raise the low Papp - a with them to give me the aspirin and extra growth scans. And it took 4 weeks and probably started the treatment late..
