TSH Schilddrüse: what does this mean exactly?

TSH (thyroid-stimulating hormone) is a key biomarker for thyroid function. Produced by the pituitary gland, it stimulates the thyroid to release T3 and T4. A TSH test is a standard blood test used to diagnose hypothyroidism (elevated TSH) or hyperthyroidism (low TSH). The normal range is typically 0.4–4.0 mU/L, but varies by lab. MyBody-X may offer TSH as part of a biomarker panel, not a DNA test. The evidence for TSH's clinical utility is strong (human-strong). However, a single TSH value is insufficient for a full thyroid assessment; additional markers like fT3, fT4, and antibodies are often needed. Caveat: TSH can be affected by time of day, medications, or non-thyroidal illness.
