ADH, produced in the supraoptic and paraventricular locations of the hypothalamus, acts on the collecting tubules of the kidney to cause increase in permeability to water and urea. ADH release is triggered by a number of both osmotic and nonosmotic stimuli.

Here, we evaluate the potential of copeptin measurement as a surrogate marker of AVP/ADH secretion for the direct diagnosis of suspected SIADH in cancer patients. Forty-six unselected cancer patients with serum sodium concentrations permanently below 135 mmol/L were included in this study.

Arginine vasopressin (AVP), also known as antidiuretic hormone (ADH), is a hypothalamic polypeptide that is transported along the axons of the synthesizing neurons into the posterior pituitary gland. Correlation with the ADH assay has shown poor agreement between ADH and Copeptin. However, this is not reflective of the Copeptin assay, but rather whether pre-analytical conditions were maintained for ADH analysis.

Copeptin is a reliable surrogate marker of vasopressin (AVP/ADH) Copeptin helps to rule out AMI with Troponin. Copeptin frigjøres fra nevrohypofysen i ekvimolare mengder med ADH, og kan derfor brukes som en surrogat markør for ADH. Analytisk er den mere stabil, og enklere å analysere enn ADH. ADH fases ut fra 01.10.19, dvs ADH-prøver som mottas etter dette vil bli analysert for copeptin. Copeptin, the C-terminal portion of provasopressin, is a 39-amino acid glycopeptide of unknown function . Copeptin may have a role during the intracellular processing of provasopressin, possibly contributing to correct structural formation of the precursor, which leads to efficient proteolytic maturation . Antidiuretiskt hormon, ADH eller argininvasopressin, AVP, är ett peptidhormon och neuropeptid som ingår i kroppens långsiktiga reglering av främst osmoreglering samt blodplasmans koncentration av natrium, samt som en följd av detta blodvolymen. Vorteile von Copeptin gegenüber ADH Bleibt im Serum auch bei Raumtemperatur mehrere Tage stabil. Keine analytisch relevante Bindung an Thrombozyten – weniger falsch erhöhte Werte Copeptin ist ein größeres Molekül als ADH, sodass sensitivere und präzisere Methoden genutzt werden können.

Measurement of ADH is difficult in part because of its short half-life. Copeptin is more stable and can be measured by immunoassay.

To overcome these obstacles, copeptin, the C‐terminal fragment stemming from the ADH precursor, has been increasingly used as a stable clinical measure for ADH. Furthermore, copeptin has been recognized as a biomarker of insulin resistance in obesity.

ADH release is triggered by a number of both osmotic and nonosmotic stimuli. A recent quantitative analysis of 50 patients with SIADH, which underwent serial measurements of copeptin during hypertonic saline infusion, revealed five distinct types of osmoregulatory defect ("type A to E") without affiliation to specific underlying diseases. Copeptin, a 39-amino acid glycopeptide, is the C-terminal part of the prohormone of arginine vasopressin (AVP) or antidiuretic hormone (ADH). The pre-pro-vasopressin precursor is synthesized and processed into its three components – AVP, Neurophysin II and Copeptin – within the hypothalamus; afterwards these products are transported along the neuronal axons in the granules of the posterior To overcome these methodological challenges, copeptin, the C‐terminal fragment stemming from the ADH precursor, has been increasingly used as a stable clinical measure for vasopressin release (Christ‐Crain, Morgenthaler, & Fenske, 2016). Copeptin measurement in plasma was initially thought of as a sensitive marker in the diagnosis of levels of copeptin,22 while patients with hyponatremia and the syndrome of inappropriate ADH secretion (SIADH) have elevated copeptin in their circulation.

Copeptin may have a role during the intracellular processing of provasopressin, possibly contributing to correct structural formation of the precursor, which leads to efficient proteolytic maturation (7). Background: Copeptin, the C-terminal moiety of provasopressin, is cosecreted with vasopressin. Copeptin may be a useful parameter to characterize disorders of water homeostasis and can be readily measured in plasma or serum. However, it is unknown to date how circulating copeptin and vasopressin levels correlate at different plasma osmolalites. ADH, produced in the supraoptic and paraventricular locations of the hypothalamus, acts on the collecting tubules of the kidney to cause increase in permeability to water and urea. ADH release is triggered by a number of both osmotic and nonosmotic stimuli. A recent quantitative analysis of 50 patients with SIADH, which underwent serial measurements of copeptin during hypertonic saline infusion, revealed five distinct types of osmoregulatory defect ("type A to E") without affiliation to specific underlying diseases.
