How many weeks do you have to be to get this testing?

10 weeks.

My doctor made me take 2 seperate parts one at 13 weeks and my next at 16 weeks. Does that sound right?

I tested at exactly 10w0d

That sounds like a different blood test - the older less reliable one that comes with an ultrasound "NT" scan.

I'm not sure, I would follow up with your doctor. My doctor had my MaterniT21 test scheduled for 11w5d. They also did an ultrasound that day. I know that they usually wait for 12w for the NT scan...

I'm not exactly sure why they did the ultrasound with the Mat21..they said they always do at my office. The genetic counsele called me with the results last week...negative, yay! Today I had an appointment and I saw the Mat21 paperwork. It definitely said MaterniT21.

I have no idea. I got my blood test for the NT scan at 10w2d and the NT scan at 12w0d. It seems to vary a bit for all of these? Def go by yours drs recommendations.

The Dr. did a U/S the day of my Mat21 testing as well. He measured crown to rump and turned the sound up so I could hear the heartbeat.

 He took maybe 5 minutes max.
