Meredith,
My heart went out to you, similar boat except I am meatatartian! thanks for info on KN cells so helpful and also thanks melbel. also want to do it to rule it out, apparantly 50% of those with thyroid antibodies have elevated active NK cells, 1 in 2 chance for me.

Am going to see Dr Nick Lolagis on mon, and according to nurse he does uterine biopsy for NK cells. My friend says he is very gruff!

Do you reckon that the NK cells cause auto immune problems, maybe I am totally off track here.

Good news my iron is up from ferritin 21 to 49, am v pleased as has been low for 2 years despite red meat intake. Finally slogged it out taking 100mg iron tabs, will keep taking to get it ferritin up around 100, optimal according to doc.
