Genetic testing for HLA-DQ2/DQ8 has high sensitivity (>95 %) to rule out celiac disease, as nearly all affected individuals carry these risk alleles. Stress itself does not alter the HLA gene profile – the test result remains stable throughout life. However, chronic stress can impair gut barrier function ('leaky gut') and modulate immune responses, potentially influencing antibody levels (tTG-IgA). Yet no robust studies demonstrate a direct effect of stress on the diagnostic accuracy of celiac testing. The evidence for the genetic test is strong (human association studies), but the link to stress is speculative. A positive HLA result alone does not confirm active celiac disease – additional duodenal biopsy or serology is required. DTC tests offering only HLA are not diagnostic. Safety note: If celiac disease is suspected, consult a physician before starting a gluten-free diet, as the diet can skew diagnostic results.","area":"gesundheit","canonical_id":"gesundheit:canonical-f2d099d198bc381d5b956506","id":"public-cc15038cb2f91cb5bd7a7bb6","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: Zöliakie Test in the context of stress","score":17.51132763,"snippet":"A celiac test (typically HLA-DQ2/DQ8 genotyping or tTG-IgA antibodies) is a well-established diagnostic tool.
