my 14 year old sons blood test came back negative for celiac, i was gobsmacked, i was convinced, he cant eat wheat and we have cut out gluten he is much better afetr four weeks but not cured totally- but hes has d for three years or more i didnt expect it to go away within a weekhow reliable is this blood test? how can he have an intolerance and yet not be a celiac? hism intolerance is pretty significant- but he hasnt lost weight- doesnt have stomach ache, pains gas- no other symptoms but d whcih has been relieved without wheat- if nhe was still eatign wheat i dont think he would be here still- he would ahve topped himself i reckon- how much can i rely on this test for the true picture? how come hes not a cleiac and yet cant have gluten
