However, diagnosis is not based solely on a DNA test: HLA-DQ2/DQ8 genotyping indicates genetic susceptibility (necessary but not sufficient). Confirmed diagnosis requires serology (tTG-IgA) and duodenal biopsy. A standalone genetic test without clinical follow-up is misleading. For athletes, undiagnosed celiac disease can impair recovery and performance, but the test alone does not replace medical evaluation.
