What to watch with TSH Schilddrüse and allergy?

The question about TSH (thyroid) and allergy is complex. TSH is a hormone regulating thyroid function; abnormal levels may indicate thyroid disorder. Allergies are immune-mediated. There is some observational evidence linking thyroid autoimmunity (e.g., Hashimoto's) with allergic conditions (e.g., allergic rhinitis), but the evidence is not strong enough for causal claims. A home test measuring TSH can provide a screening hint, but a single measurement is not diagnostic. Moreover, TSH levels do not predict specific allergies. For allergies, specific IgE tests or skin prick tests are required. Caution: Do not change supplements or diet based solely on a home test. Consult a doctor if results are abnormal.
