Just had my results yesterday (NIPT/Harmony) and thankfully it has come back as low probability (1/10,000).
However the fetal cfDNA was only 5.5%, so much so it wasn’t enough to determine fetal sex. That it in itself doesn’t matter, we were just curious, but I am now paranoid that if there wasn’t enough to determine sex, what if it wasn’t enough for an accurate NIPT result.
I think the minimum fraction needed is 4%, but the ideal / expected ? one is 10%.
For context I was 10+4 when I did the test and my BMI is 31.
Has anyone got any similar experiences ?
