Anti Diuretic Hormone (Vasopressin), EDTA Plasma


Reference Range

Vasopressin is a peptide hormone secreted by the neuronal cells of the hypothalamus and stored in vesicles at the posterior pituitary. Its rate of secretion is under the control of cerebral osmoreceptors and baroreceptors in the carotid arteries. One of the most important roles of vasopressin is to conserve body water by reducing the loss of water in urine (anti-diuretic hormone), and it also raises blood pressure by inducing moderate vasoconstriction. In addition, it has a variety of neurological effects on the brain. DECREASED vasopressin release or decreased renal sensitivity to vasopressin leads to central or nephrogenic diabetes insipidus, respectively. HIGH levels of vasopressin secretion and resultant hyponatremia (low blood sodium levels) occurs in brain diseases and conditions of the lungs (small cell lung carcinoma).
