I’ve tested with the genes for celiac disease, but I haven’t yet shown any symptoms for it. What should I do?
We recommend that you undergo a blood screen every 2-3 years or immediately upon the appearance of symptoms. This is especially true for 1st-degree relatives (parents, siblings, children) of someone with celiac disease.
(Updated .)If both parents have a negative genetic screen for celiac disease, does that mean their children are also negative?
Yes, the children of two persons who don’t have the genes for celiac disease should also be free of the genes for the disease.
(Updated .)If I have a gene for celiac disease, does that I mean I have it?
Genetics don’t diagnose celiac disease. They do, however, clarify whether an individual is “at-risk” for it. If this is the case, you should closely monitor your symptoms and submit to blood tests every 2-3 years or immediately upon the onset of symptoms. When the genetic predisposition for celiac disease was detected (on Chromosome 6) researchers… Read more »
(Updated .)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… Read more »
(Updated .)Are genetic tests 100% accurate?
Rarely are scientific tests 100% accurate, but with PCR technology genetic tests are very accurate. If there is a question about testing, it may be a good idea to take a second test using a different lab.
