I did something similar (Natera's Panorama test) with my son. There was a narrow frame in which I had to have two vials of blood drawn (I think it had to be between 9-12 weeks), and my husband had to have a cheek swab. Within a couple of weeks, we had all of our results, including baby's gender. My insurance ultimately denied the $8,000 claim for the tests (YIKES) but Natera will settle for $100-250 if your insurance denies it, so it wasn't a big deal in the end. No regrets.
This time around, I have a different insurance company (a terrible one) so I have to go through a different medical provider. All they offer is Progenity, which I had the blood draws done for yesterday. It was one large and two small vials of blood. Progenity allows for the draw anytime after 10 weeks. As far as I can tell, there's otherwise really no difference between Progenity and the others, though it looks like there are some optional tests for other genetic conditions that Panorama and MaterniT don't cover (sickle cell anemia, etc.) I just had the standard panel that tests for the trisomies and more common chromosomal and gene deletion disorders. My insurance is supposed to cover it now that I'm "advanced maternal age." However, if they don't, Progenity offers a sliding fee scale based on income that starts at $50. I should have results in about two weeks.
Ultimately, in my opinion, it is a very small price to pay for extremely accurate results and reasonably noninvasive testing. I appreciate the peace of mind it offers, and if there is something terribly wrong with the baby, you know early on instead of 20+ weeks along. There's no risk of miscarriage like there is with amniocentesis. And it's far more accurate than just guessing based off of what the ultrasound tech sees on the screen.
