Negative blood test for celiac in Food Intolerance & Leaky Gut Posted January 23, 2016 · Report to Admin There is so much to be discovered by medical science regarding the human intestinal tract! Let's face it, it is not a glamorous topic! The best we can do as non-doctors is to maintain our medical records, read current research that may aid our doctors (they are humans after all) and continue to advocate for ourselves. I wish you well! Welcome to the forum! Read the great tips about cross contamination, avoiding processed foods while healing, etc. at "Newbie 101" located under our "Coping" section. If you are going to be gluten free, then make sure you really are gluten-free!
