I just found out the gender from my MaterniT21 results. I thought it just checks for Trisomy 21 and 18 and when the Dr asked if I wanted to know the sex I was surprised. It can tell you whether or not there is a Y chromosome present. In my case it didn't so I am having another girl. Its 99% accurate so of course there is a chance its incorrect. Am I the only one who didn't know this? As anyone else had the MaterniT21 tests?
Now I just have to get over the shock of having another girl!
Re: MaterniT21 & Gender
I took the MaterniT21 test, too. I am also having a baby girl. With 99%+ accuracy, the chances of it being wrong are really not worth mentioning.
Congrats on your baby girl!
I heard they can tell in about 50% of samples. We are team green so I hope they ask before spilling the beans!
I am on day 9 of waiting for my results - how long was it it until you got yours?

That's not what they told me. When they took my blood, they said they would be determining the gender with the other results and asked if I would want to know. You should be sure to tell them you do not want to know.
However, they do take two vials of blood in case there is not enough of the baby's DNA in the first one for the test. But once they get that DNA and replicate the chromosomes, they are going to be able to determine gender, too. Perhaps the two vials needed is what that 50% was referring to.
Also, my results took 8 days, but I saw that it took someone on another board 14 days.
I got my results back in a week.
Edit: 2 to 3 days not 23
