Can anyone help me please:-
My boyfriend has all manner of things going on and we can't get to the bottom of what is wrong. He has been non gluten for quite a while and his G.P. has asked him to do a coeliac/blood clotting blood test. I suspect that as he is already non-gluten nothing will show up. Would you know how long he would need to eat gluten again before a blood test to have any real answers?
