NIPT results - low fetal fraction

I just received the results from my NIPT test (taken at 10 week) everything is negative except my Fetal Fraction is at 3%. They said they like it to be at least 4. I’m making an appointment to sit down for a consultation with maternal fetal medicine (per their request) to make sure everything is ok. Anyone else experience this before? I didn’t have any issues with my son who is now 2 1/2. Thanks!

Re: NIPT results - low fetal fraction

  • Probably means you'll have to redo it - usually means there wasn't enough fetal DNA in the sample (usually because the test was done too early - typically NIPT is done at 11 weeks or later).
    Current pregnancy -
    First BFP on 1/4/22.  Due date 9/13/22.

    Four prior losses, no living children - 1 first trimester miscarriage, 1 blighted ovum, 1 chemical, and one extreme premature live birth daughter who died at 15 days old.
