Antidiuretic Hormone details
What Antidiuretic Hormone shows
Antidiuretic hormone (ADH), also called vasopressin, is produced by the hypothalamus and released by the pituitary gland to help your kidneys control how much water they retain versus excrete, playing a central role in regulating your body's fluid balance and blood sodium concentration. Too little ADH activity causes diabetes insipidus, a condition marked by excessive urination and thirst since the kidneys can't concentrate urine properly. Too much ADH relative to what the body needs causes SIADH (syndrome of inappropriate ADH), which leads to fluid retention and low blood sodium (hyponatremia). Because ADH levels can be technically difficult to measure directly, doctors sometimes rely on related markers or on water-deprivation and other functional testing, in addition to or instead of a direct ADH level.
Tests that include Antidiuretic Hormone
This test measures antidiuretic hormone. It is useful for the differential diagnosis of patients with water balance disorders, including diabetes insipidus in conjunction with osmolality and hydration status.
- Antidiuretic Hormone Also called vasopressin, this hormone helps your kidneys regulate how much water your body retains. Abnormal levels are linked to conditions affecting fluid balance, like diabetes insipidus or SIADH.
This test measures antidiuretic hormone and osmolality to aid in the diagnosis of urine concentration disorders, especially diabetes insipidus, syndrome of inappropriate ADH (SIADH), psychogenic water intoxication, and syndromes of ectopic ADH production.
- Antidiuretic Hormone Also called vasopressin, this hormone helps your kidneys regulate how much water your body retains. Abnormal levels are linked to conditions affecting fluid balance, like diabetes insipidus or SIADH.
- Osmolality Measures the concentration of dissolved particles in your blood, reflecting hydration and fluid balance.
The CIRS panel measures markers associated with Chronic Inflammatory Response Syndrome (CIRS). It aids in evaluating systemic inflammation and immune dysregulation, facilitating accurate diagnosis and tailored treatment plans for patients with CIRS-related conditions.
- Antidiuretic Hormone Also called vasopressin, this hormone helps your kidneys regulate how much water your body retains. Abnormal levels are linked to conditions affecting fluid balance, like diabetes insipidus or SIADH.
- Complement C4a An activation fragment produced when complement protein C4 is triggered. Reflects how active your complement immune pathway currently is.
- Leptin A hormone released by fat cells that helps regulate appetite and energy balance. Levels generally rise with increased body fat.
- Matrix Metalloproteinase-9 (MMP-9) An enzyme involved in breaking down tissue, including artery plaque, and contributing to inflammation. Studied in cardiovascular and certain chronic inflammatory conditions.
- Melanocyte-Stimulating Hormone (MSH) A pituitary-derived hormone involved in skin pigmentation and, more recently, studied for roles in appetite and inflammation regulation.
- Osmolality Measures the concentration of dissolved particles in your blood, reflecting hydration and fluid balance.
- Vascular Endothelial Growth Factor (VEGF) A signaling protein that promotes new blood vessel growth. Studied in cancer, wound healing, and certain inflammatory or eye conditions.
- Complement C3a desArg An activation fragment produced when complement protein C3 is triggered. Reflects how active your complement immune pathway currently is.
- Transforming Growth Factor Beta 1 (TGF-ฮฒ1) A signaling protein (cytokine) involved in tissue repair, immune regulation, and inflammation; studied in various chronic inflammatory and fibrotic conditions.
