i finally got referred to a gastroenterologist and saw his nurse practitioner last week. she scheduled me for a blood panel and upper endoscopy, neither of which i have done yet. i told her that i was worried about false negatives that may occur because of my 8 month gluten free diet. she said that i should not worry about this, and that it would show no matter if i was on a gluten free diet or not. this goes against everything i have read and heard.. but is she right? should i go back on gluten before the testing? ask for a second opinion? i live in the panhandle of florida, and celiac's is not a well known disease, nor is there many gastorenterologists around here. please- i do not want to have to repeat these tests. any help or advice is appreciated.
