促甲状腺激素(TSH)是垂体前叶分泌的一种分子量为28KD的糖蛋白激素。促甲状腺激素有两个亚基,即α和β。促甲状腺激素的α亚单位与LH、FSH和α糖蛋白激素中的hCG亚单位相似。促甲状腺激素(TSH)正向刺激甲状腺激素T4和T3的产生。循环T4和T3通过负反馈调节TSH分泌。促甲状腺激素(TSH)的产生也受到下丘脑分泌的素(TRH)...
TSH stimulates the thyroid gland to synthesize and secrete triiodothyronine (T3) and T4. TSH production is reduced in response to high T3/T4 levels and increased in response to low T3/T4 levels. When pituitary disease is not suspected, ... ...
Thyroid hormones (T3 and T4) inhibit the synthesis and release of TSH through binding to the thyroid hormone receptor. Somatostatin and melanin-concentrating hormone (MCH) also inhibit TSH release. In the pars tuberalis, TSH secretion is regulated by melatonin that transmits photoperiodic information...
The most common and effective TSH test is a blood test. In addition to analyzing your TSH level, your doctor looks for T4 (thyroxine) and T3 (triiodothyronine) as well, which the thyroid gland produces. These three hormones give doctors an indication of which gland they should focus on, th...
TSH is also not necessarily sufficient to monitor hypothyroidism during pregnancy; T4 and free T4 are often recommended. Other thyroid tests that may be performed, depending on the clinical situation, include (T3), free T3, reverse T3, and thyroid antibody tests. ...

T4 (free or total), but only by elevation of T3 (triiodothyronine). Therefore, if thyrotoxicosis is clinically suspect, and T4 and FTI are normal, the test "T3 -RIA" is recommended (this is not the same test as "T3 uptake," which has nothing to do with the amount of T3 in the ...
