How Do You Get Diagnosed with Celiac Disease

How Do You Get Diagnosed with Celiac Diseaseにまつわる最新トピックを分かりやすく発信ます。

Sometimes, the blood test is borderline, and the biopsy is ambiguous. That’s when they check your genes—specifically HLA-DQ2 and HLA-DQ8. Almost every celiac has one of these. But here’s the kicker: 30% of the general population has these genes too, and most never develop celiac. So a positive gene test doesn’t guarantee you have it, but a negative test basically rules it out.

Think of it as the tiebreaker in a confusing game. If you have the genes and the symptoms, the puzzle pieces fit. If you don’t have them, your doctor will start looking for other culprits—like IBS or a wheat allergy.
