Evidence check: TSH Schilddrüse in the context of Allergie

The question of a link between TSH (thyroid-stimulating hormone) and allergies is complex. The provided context contains no specific information on TSH, thyroid function, or allergies. In research, thyroid hormones can modulate the immune system – e.g., TSH influences dendritic cell and T-cell activity. Some studies report elevated TSH in allergic individuals, but evidence is inconsistent and mostly observational. Consumer DNA tests reporting TSH-related SNPs (e.g., in PDE8B, TSHR) have very small effect sizes and are not validated for allergy prediction. Clinical relevance is unclear. Relying solely on genetic risk assessment for TSH in the allergy context is not recommended. Instead, TSH should be measured via blood test and interpreted by a physician. Evidence grade: unclear from context. Caveat: No action without medical consultation.
