Celiac disease (CD) is caused - in genetically predisposed individuals - by abnormal intestinal permeability and abnormal immune response to gluten. The inflammatory autoimmune response damages the lining of the small bowel. Gluten sensitivity can cause similar symptoms but without the same level of tissue damage. This test helps differentiate between CD and gluten sensitivity by evaluating the serum titers of IgA and IgG for deamidated gliadin peptide, gliadin and gluten.  It is a simple dried blood sample which can be done in the comfort of your home.  Please note, You have to be eating Gluten/Wheat for at least 6 weeks to take the test.  
 
Please note, I offer this test with a consultation (go to My Services for more information).  Food intolerances are only part of a gut health picture.  I strongly recommend a consultation to discuss how to repair the gut and strengthen the immune system.
