thyrotropin

 [thi´ro-tro″pin, thi-rot´rah-pin]
a hormone secreted by the anterior lobe of the pituitary gland that has an affinity for and specifically stimulates the thyroid gland. Called also thyroid-stimulating hormone.
thyrotropin alfa a recombinant form of human thyrotropin; it binds to thyrotropin receptors and stimulates the steps in thyroid hormone synthesis, including iodine uptake and synthesis and secretion of thyroglobulin; used as a diagnostic adjunct in serum thyroglobulin testing, with or without radioiodine scanning, in followup of patients with well-differentiated thyroid cancer, administered intramuscularly.
thyrotropin-releasing hormone stimulation test (thyrotropin-releasing hormone test) a thyroid function test that assesses release of thyrotropin by the pituitary gland; a bolus of thyrotropin-releasing hormone is administered and serum concentrations of thyrotropin are assessed at intervals; if serum levels do not increase within 30 to 40 minutes, the pituitary thyrotrophs are dysfunctional. Called also TRH test and TRH stimulation test.

thy·rot·ro·pin

(thī-rot'rō-pin, thī-rō-trō'pin),
A glycoprotein hormone produced by the anterior lobe of the hypophysis that stimulates the growth and function of the thyroid gland; also used as a diagnostic test to differentiate primary and secondary hypothyroidism.
[for thyrotrophin, fr. thyro- + G. throphē, nourishment; corrupted to -tropin, and reanalyzed as fr. G. tropē, a turning]

thyrotropin

/thy·rot·ro·pin/ (thi-rot´rah-pin) thyroid-stimulating hormone; a hormone of the anterior pituitary gland having an affinity for and specifically stimulating the thyroid gland.
thyrotropin alfa  a recombinant form of thyrotropin used as a diagnostic adjunct in serum thyroglobulin testing in followup of patients with thyroid cancer.

(-fĭn)
n.
A hormone secreted by the anterior lobe of the pituitary gland that stimulates and regulates the activity of the thyroid gland. Also called thyroid-stimulating hormone, thyrotropic hormone.

thy·rot·ro·pin

(thī'rō-trō'pin)
A glycoprotein hormone produced by the anterior lobe of the hypophysis that stimulates the growth and function of the thyroid gland; it also is used as a diagnostic test to differentiate primary and secondary hypothyroidism.
Synonym(s): thyroid-stimulating hormone, thyrotrophin.
[fr. thyro- + G. throphē, nourishment; corrupted to -tropin, and reanalyzed as fr. G. tropē, a turning]

Thyroid stimulating hormone (thyrotropin)

A hormone that stimulates the thyroid gland to produce hormones that regulate metabolism.
Mentioned in: Pituitary Dwarfism

thyrotrophin

; thyrotropin thyroid-stimulating hormone (TSH); secreted by anterior pituitary; stimulates thyroid gland growth/function

thy·rot·ro·pin

(thī'rō-trō'pin)

thyrotropin

a hormone secreted by the anterior lobe of the pituitary gland that has an affinity for and specifically stimulates the thyroid gland. Called also thyroid-stimulating hormone (TSH).

thyrotropin releasing hormone (TRH)
a tripeptide produced in the hypothalamus and released into the hypothalamohypophyseal portal circulation to reach the adenohypophysis where it triggers the release of thyroid-stimulating hormone. Called also TSH releasing factor, TSH releasing hormone.
thyrotropin releasing hormone stimulation test, response test
measures serum levels of thyrotropin-stimulating hormone (TSH) before and after administration of TRH.
thyrotropin-stimulating hormone (TSH) stimulation test, response test
measurement of serum levels of thyroid hormone(s) (T3 and/or T4) before and after the administration of TSH is a more reliable indicator of the functional capacity of the thyroid glands than single determinations and may distinguish between primary and secondary hypothyroidism.
