TSH Test ( 1 )
Thyroid stimulating hormone is a 28,000 dalton glycoprotein derived from anterior pituitary and is Stimulated by thyrotropin-releasing hormone and inhibited by thyroid hormone in a classical endocrine negative-feedback loop. It is synthesized by thyrotropes present in anterior pituitary and stored in secretory granules. We provide Tsh test cost at a very competitive price. Further, it is released into the circulation in a regulated manner, binds to thyroid cells by interacting with a specific receptor and activates them to release thyroid hormones (thyroxine and triiodothyronine). It also stimulates the aggregation of porcine thyroid cells in follicles and its presence is necessary to maintain the follicular architecture.
TSH is chemically related to the pituitary gonadotropins, luteinizing hormone and follicle stimulating hormone. The physiological roles of TSH include stimulation of differentiated thyroid functions, such as iodine uptake and organification, production and release of iodothyronines from the gland and promotion of thyroid gland. TSH also acts as a factor protecting thyroid cells from apoptosis and plays a critical role in ontogeny.
