My DS's doctor wants to test him for Celiac even though I took him off gluten 2 years ago. His test 2 years ago was negative (blood and biopsy) but I took him off gluten anyway because it reduced his number of diapers per day from 8 down to 1 or 2.
I told the doctor that he doesn't eat gluten and that I didn't think a blood test for Tissue Antigliadin Antibody would show anything for that reason. She insists it will and that the biopsy is the only test that requires the patient be eating gluten at the time. Am I wrong? I thought one had to be consuming gluten for the blood test to show a reaction.
Thanks in advance for any insight. I'm keeping him off gluten regardless, but I'm curious as to who's right regarding this testing business.
