Is TSH Schilddrüse useful for Haut?

TSH (thyroid-stimulating hormone) is a standard marker of thyroid function, not a direct skin biomarker. Abnormal TSH can indicate thyroid dysfunction, which secondarily affects the skin – e.g., dry, scaly skin in hypothyroidism or moist, warm skin in hyperthyroidism. However, TSH alone is not a validated skin-specific test. The evidence for its usefulness in skin assessment is mechanistic and indirect, not supported by robust clinical studies for dermatological outcomes. MyBody-X may include TSH in a thyroid panel, but without additional markers (fT3, fT4, antibodies) its relevance for skin issues is limited. Caveat: normal TSH does not rule out thyroid-related skin changes, and skin conditions are often multifactorial. Professional medical evaluation is recommended for persistent skin concerns.
