I think it's pretty useful when you have a mystery condition and all the doctors are taking random guesses at you...I found pretty useful stuff there, i have ALL genetic risk factors for celiac disease wich is up to 87% attributable to genetics, and 7X risk compared to the average joe, now i really find some support to a gluten free diet, i will try it for a few months to see if there's any improvement. In my case the *beep* i experience can be caused by only a handful of things so having some support to what i think is helpful, especially when it could be fixable with something as simple as a diet. As a coincidence i have increased markers for all autoimmune stuff known to man except rheumatoid arthritis and MS. Knowledge is power, i got past the als scare a loong time ago so i don't worry about diseases that aren't curable, cuz there's no point right? i do worry i could do something to improve my condition and i'm not doing it because my doctors don't know what's going on.I didn't ask for your criticism, i just asked if someone has done it already and wants to share ... I don't see why you saw my post as a recommendation to get screened ...
