Hi there. The Auto Immune Screening blood test (that's it name, grand hey!!) is when you have several vials of blood sent to Chicago for testing.
The first thing you need to be aware of it is not cheap, approx £800.00, but for me because they found out the problem it was definitely money well spent.
I have a history of excellent embryos and no worries with partner's contribution

but when the embryos were put back either nothing, or +ve but early m/c
This test checks for several different things, amongst them something called Natural Killer Cells (NK) which, if you have too high a level, treat the embryo as a foreign body and kill it off.
I don't know what your history is so don't know if this is relevant to you. I had no other obvious issues
Hope this helps - anything else you want to know, just ask
