5 different tests for celiac/ gluten/ wheat problems


Wendy says: “My daughter has had 2 negative results for coeliac but still has a major problem with wheat!  Are there other tests for wheat intolerance?”
My reply:
When she says "2 negative results for celiac" I do not understand the problem ...  because there are at least 5 different tests for celiac/gluten/wheat problems. And, none can completely rule out a gluten problem: the only way to see if gluten is truly affecting you is to go on a gluten-free diet for a year and see if you get better.  But get your blood tests first.
The 5 tests:
  1. Gluten blood tests: IgG-gliadin
  2. Tissue damage blood tests: tTG, EMA, DGP
  3. Gene test: HLA DQ2/DQ8
  4. Endoscopy: a small bowel biopsy whilst still eating gluten
  5. Skin tests, EAST/RAST: specific IgE tests for wheat allergy.
Each of these tests needs interpretation in the context of your current diet and symptoms.
We will help you through this at the Childrens Clinic |Allergy Centre, Christchurch.
