I just had results from my nipT which thankfully came back low risk for everything. But the fetal fraction is only 3%. I had bloods drawn at 10+1 and am a bit concerned about what this low level means. I can’t seem to get answers from google and didn’t do the tests via a clinic but with a blood test company (concepto) so no doctor on hand to answer my questions.
Does this indicate anything is wrong and/or does it make the test results less valid?
