I had a high risk NIPT for Trisonomy 18 that was ultimately diagnosed with an amnio. I chose to TFMR at 17 weeks.
@stan783 Was this for your combined screening? I had similar results and was referred for additional screening (NIPT, etc). The combined blood test is not remotely diagnostic, but these results possibly indicate more investigation is needed.
