Description:
Antidiuretic Hormone Blood Profile (Labcorp)
This test measures several factors which are related to kidney function and water balance in the body. The Antidiuretic Hormone (ADH) Profile provides values for ADH and Osmolality. Osmolality refers to the concentration of dissolved particles such as electrolytes and waste products in the blood. An increase in osmolality triggers the production of the hormone ADH by the hypothalamus. Production of ADH typically causes the kidneys to retain water rather than removing it from the body through urine. The retained water dilutes the blood and decreases osmolality. In this way, the relationship between ADH and osmolality maintains a healthy water balance in the body. ADH deficiency can result in frequent urination, dehydration, excessive thirst, and high sodium levels. Excessive ADH levels can cause increased blood pressure, nausea, lethargy, disorientation, and low sodium levels. Irregular ADH levels can be caused by a number of conditions including several types of diabetes and various forms of cancer.
ADH and Osmolality are ordered together because ADH levels are not typically useful by themselves. This testing is sometimes ordered along with an Electrolyte Panel.
Turnaround for this test is typically 8-10 business days.
