I've just been offered this test (due to my age, 40) by my Obstetrician which costs $900 and is done at 9 weeks. It is way less invasive than amnio, and more accurate than nt alone, consisting of a bt for mum and a scraping from dad. The results are available sooner than the other tests too which would allow consideration of not continuing the pregnancy prior to 12 weeks if that was the mothers wish.
I was wondering if anyone has used this? The results indicate high risk or low risk with 99% accuracy apparently and so therefore you avoid the risks of amnio.
any thoughts or experiences?
