Schilddrüsenwerte

Schilddrüsenwerte, also known as thyroid function tests, are blood tests used to assess how well the thyroid gland is working. The thyroid is a small, butterfly-shaped gland located in the neck that produces hormones regulating metabolism, energy levels, and many other bodily functions. The most commonly measured Schilddrüsenwerte include TSH, T3, and T4.

TSH, or thyroid-stimulating hormone, is produced by the pituitary gland and signals the thyroid to produce more or less thyroid hormone. High TSH levels usually indicate an underactive thyroid (hypothyroidism), while low TSH levels often suggest an overactive thyroid (hyperthyroidism). T4, or thyroxine, is the primary hormone produced by the thyroid. It exists in two forms: free T4 (fT4) and total T4. Free T4 is the active form that circulates in the blood and is not bound to proteins. T3, or triiodothyronine, is another thyroid hormone, and like T4, it also exists in free (fT3) and total forms. T3 is considered more potent than T4 and is derived from T4 in the body.

Abnormal Schilddrüsenwerte can indicate various thyroid conditions, including hypothyroidism, hyperthyroidism, Hashimoto's thyroiditis (an autoimmune disease causing hypothyroidism), and Graves' disease (an autoimmune disease causing hyperthyroidism). The interpretation of these values should always be done by a healthcare professional in the context of the individual's symptoms and medical history. Doctors may also measure thyroid antibodies to help diagnose autoimmune thyroid disorders. Regular monitoring of Schilddrüsenwerte is crucial for individuals with known thyroid conditions or those undergoing treatment.
