Hi MTB, just to share my experience with all. When I was 16wks preg with my 2nd child. I failed my blood test, high chance of down. Nonetheless, I was so worried that I cried for a few days, what's worst that hubby didn't allow me to do amino. However, I was hesitant too, as it will be a 2-3wks of wait, it's way too long for an anxious mother. So I went online search high and low abt the risk of this amino test and what else can be done. And so i found professor Mahesh from the web. We immed made a appt with him for consultation. Prof told me about flash fish, a test which enable me to know my 1st results in 24hrs, 2nd results in 48hrs and 3rd results in a wk! Of course I went ahead with it approve by my hub. Indeed, my results came out in 24hrs. It did some assurance to me.
