Hi Jaye,
I'm from Australia too, and noticed you hadn't had a reply to this query. I also would like to pursue this - as I've had both a miscarriage and 2 failed ivf treatments (both with perfect blastocysts).
Alot of the ladies that have talked about getting the testing for NK cells (+ APA & ATA testing) have referred to Dr. Beer - who has a clinic in London and California, not New York.
Here is the link to the website:
http://repro-med.net/
They have a section on Collaborating Doctors - you can send an email and they'll advise if they have any. I just sent the email and am hoping there is someone in Australia.
I think I remember one of the others saying her doctor was prepared to collaborate and follow the protocol outline - once she'd done the testing.
The funny thing with the website is - you can register and go and order up all the tests yourself - get an online consultation.
Anyway, I'm arming myself with as much information on this as I can - so when I have my next appointment I can go thru it all with my doctor.
Not sure if any of this helps?
