I just took it today and the genetic counselor said a week to ten days for results. She did tell me that there can be false positives with the test, so that is why they recommend amino if there are issues, which is 100 percent accurate. I am in the same boat as you and am quite nervous about the results.
I had mine taken on the 27th and I am assuming it will take even longer with New Years in there. Still no word and I am anxious as I had a Trisomy 18 loss last March.
Re: maternit21 test
It’s DNA based. So it’s really very accurate.
