Nipt result- help pls

Pavi

Hi all i just got my nipt results back. Thank god all is well. And i am having a girl baby. 6 months back i had a medical teemination of downsyndrome fetus, which was severely affected fetal hydrops.

My question is can anyone say if my nipt this time is reliable. Because fetal fraction is just 7%. I was just 10w 1d when i took the test.
