Frequently Asked Questions
How does a genetic test rule out celiac disease?
Two genes are responsible for celiac disease (HLA-DQ2 & HLA-DQ8). If you have either of them, then you have the potential for the disease to activate at any age. Having the genetic test is important for two reasons: to understand your risk factor for the disease and to understand the prevalence that your 1st and 2nd-degree relatives have for the disease.
To be clear, the genetic test does not diagnose that you have the disease, only the possibility for you to have it. On the other hand, if you don’t have the genes for celiac disease then the disease is not likely to be causing your symptoms. July, 2012
