ADH-Antidiuretic Hormone (Vasopressin) near me in Mumbai

Antidiuretic hormone (ADH), also known as vasopressin, is produced in the hypothalamus and released from the pituitary gland. Its main role is to maintain proper water balance in the body by acting on the kidneys to reduce water excretion. When the body needs to conserve water (such as during dehydration), ADH levels increase, prompting the kidneys to reabsorb more water into the bloodstream. Conversely, when water intake is adequate or excessive, ADH levels drop, allowing more water to be excreted in urine.

The ADH-Antidiuretic Hormone (Vasopressin) test is often recommended when there is suspicion of disorders affecting water balance, especially in individuals with symptoms like excessive thirst, frequent urination, dehydration, confusion, seizures, electrolyte imbalances, or unexplained low blood sodium levels. It is also done to diagnose and monitor conditions related to ADH secretion or disorders that impact water balance. This test also plays an important role in the evaluation of central or nephrogenic diabetes insipidus and syndrome of inappropriate antidiuretic hormone secretion (SIADH). Additionally, it is useful in assessing SIADH associated with neoplasia, pulmonary disorders, central nervous system (CNS) disorders, and with certain medications, or in cases where there is suspected damage to the hypothalamus or pituitary gland.

No special preparation is needed before taking this test. However, the doctor should be informed about any medications being taken or any recent infections, as these can affect results.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Do not self-medicate and always consult a doctor to understand the test results correctly.
