This is an email from my doctor regarding the abnormal test:

"Your total IgA (Immunoglobulin) was a little low, it's indicative that your immune system isn't overly active. The other two values that are part of the Celiac panel were negative and those are the improtant ones to look for when trying to identify Celiac disease. We can discuss it further at your follow up as far as what it all means in regards to your symptoms. With these findings and also knowing you had a normal appearance of the small bowel tissue on EGD, it's very unlikely that you have Celiac disease"
