Thyroid Stimulating Hormone (TSH)

Thyroid Stimulating Hormone antibody (also known as TSH or thyrotropin) is a peptide hormone synthesized and secreted by thyrotrope cells in the anterior pituitary gland, which regulates the endocrine function of the thyroid gland. Thyroid Stimulating Hormone antibody may be a useful marker in the classification of pituitary adenomas and can aid in the differential identification of primary and metastatic tumors of the pituitary. TSH secreting pituitary adenomas is a very rare cause of hyperthyroidism.
