A peptide hormone that stimulates growth, cell reproduction and regeneration in humans and other animals. It is a type of mitogen which is specific only to certain kinds of cells. Growth hormone is a 191-amino acid, single-chain polypeptide that is synthesized, stored, and secreted bysomatotropic cells within the lateral wings of the anterior pituitary gland.
A hormone secreted by the adrenal glands that sit above the kidneys. Known as the "stress hormone," cortisol makes blood pressure and blood sugar levels rise. Chronic elevated blood pressure can increase an individual's risk for heart disease, high blood pressure, diabetes and obesity. Effectively managing stress may also help keep cortisol levels down and protect the immune system. Cortisol plays an important role in helping the body release insulin, maintain glucose levels and keep the immune system healthy.
DHEAS (Dehydroepiandrosterone sulfate) tests the function of your adrenal gland.
TSH (Thyroid Stimulating Hormone)
test is used to check for thyroid gland problems. TSH is produced when the hypothalamus releases a substance called thyrotropin-releasing hormone (TRH). TRH then triggers the pituitary gland to release TSH
TSH causes the thyroid gland to make two hormones: triiodothyronine (T3) and thyroxine (T4). T3 and T4 help control your body's metabolism.
Triiodothyronine (T3) and thyroxine (T4) are needed for normal growth of the brain, especially during the first 3 years of life. A baby whose thyroid gland does not make enough thyroid hormone (congenital hypothyroidism) may, in severe cases, be mentally retarded. Older children also need thyroid hormones to grow and develop normally.
This test may be done at the same time as tests to measure T3 and T4.
Pituitary function test useful in the detection of prolactin-secreting pituitary tumors (microadenomas, macroadenomas) with or without galactorrhea, with or without structural evidence of sellar enlargement. An adult female premenopausal patient having amenorrhea and galactorrhea is highly suspect of pituitary prolactinoma and is a candidate for radiologic evaluation of the pituitary as well as serum prolactin levels.
Testosterone testing is used to evaluate androgen excess or deficiency related to gonadal function, adrenal function, or tumor activity. Testosterone levels may be helpful in men for the diagnosis of hypogonadism, hypopituitarism
Parathyroid Hormone (PTH)
It is a protein hormone released by the parathyroid gland. The parathyroid glands are located in the neck, near or attached to the back side of the thyroid gland. Parathyroid hormone controls calcium, phosphorus, and vitamin D levels in the blood and bone.
A steroid hormone (mineralocorticoid family) produced by the outer section (zonaglomerulosa) of the adrenal cortex in the adrenal gland.It plays a central role in the regulation of blood pressure mainly by acting on the distal tubules and collecting ducts of the nephron, increasing reabsorption of ions and water in the kidney, to cause the conservation of sodium, secretion of potassium, increased water retention, and increased blood pressure.Whendysregulated, aldosterone is pathogenic and contributes to the development and progression of cardiovascular and renal disease. Aldosterone has exactly the opposite function of the atrial natriuretic hormone secreted by the heart.
Insulin Free and Total
Insulin is found in your body in many forms. Bound insulin is attached to other proteins. This often occurs in people with diabetes who are treated with insulin. Free insulin is not attached to other proteins. Total insulin measures both free and bound insulin.The hormone insulin plays a key role in keeping your blood sugar at the right level. Too little insulin leads to a certain type of diabetes. High levels of insulin can harm your health by leading to hypoglycemia, or low blood sugar.
