Thyroid test (TSH)
What is thyroid stimulating hormone (TSH)?
Thyroid stimulating hormone (TSH), or thyrotropin, is the primary regulator of the functional state of the thyroid gland. Its production and release is stimulated by the hypothalamic thyrotropin-releasing hormone (TRH) at the pituitary gland and possibly the hypothalamus and is controlled by the levels of the thyroid hormones (thyroxine-T4 and triiodothyronine-T3).
TSH levels increase in cases of primary hypothyroidism. The diagnosis of hypothyroidism is done by finding a low total or free T4 value and is confirmed by an elevated TSH level. Mild primary hypothyroidism may be more difficult to diagnose by measuring the level of total and free T4, because the total and free T4 may sometimes be within the normal range. In these cases, TSH tests are useful for diagnosis, as TSH levels are increased. In hyperthyroidism, levels of T3 and T4 increase and the level of TSH is decreased.
