Deb - I have no idea about NK. Just confused about the bit below. Are both the CD56 meant to be + or one + and one - like the CD16?????

"There is a special class of NK cells (CD16-, CD56+) in the placenta that promotes fetus survival. Opposing is another group of NK cells (CD16+, CD56+), if these opposing cells are active they are toxic to the placenta and may cause a miscarriage."

I find the information fascinating and reassuring to know I am not alone and that others have questioned the treatment they have been offered. I didn't challenge it with Caitlyn - and it may of may not have made a difference, but maybe it would have. *alf* now has the benefit of hindsight.
