The copeptin assay may be a useful alternative to direct measurement of AVP concentration. Copeptin, the C-terminal moiety of provasopressin, is cosecreted with vasopressin.

AVP has important physiological functions, including vascular tonus, the homeostasis of fluid balance and regulation of the endocrine stress response. Copeptin eller CT-proAVP är en glykopeptid på 39 aa som kommer från samma precursor som vasopressin (AVP, även kallat ADH). Syntesen av copeptin och vasopressin sker ekvimolärt i hypothalamus och lagras i hypofysen. Vasopressin är en viktig regulator i vattenbalansen, påverkar hemodynamiken och har en avgörande roll för Copeptin, the C-terminal segment of the arginine vasopressin prohormone, is an arginine vasopressin surrogate with high ex vivo stability that is easy to measure.

Copeptin is the more stable C-terminal portion of ADH. Copeptin is produced in the hypothalamus and secreted from pituitary in similar amounts to ADH [1] , [12] , [19] . Copeptin has been reported to be elevated in some critical acute and chronic conditions such as vascular disorders, heart failure, etc.

Copeptin - The Copeptin test is used in the diagnosis of central diabetes insipidus and in the differential diagnosis of central or nephrogenic diabetes insipidus. It is a reliable surrogate marker for arginine vasopressin (AVP).

It can therefore be reliably used as a surrogate marker for ADH. The correlation between copeptin and AVP for 110 samples was r = 0.78 (P <0.0001). Conclusions: Copeptin is stable for days after blood withdrawal and can be quickly and easily measured. The copeptin assay may be a useful alternative to direct measurement of AVP concentration. 3. Copeptin ADH 4.

Copeptin is a 39-amino acid glycopeptide, the C-terminal part of the AVP precursor (CT-proAVP), and is a stable and sensitive surrogate marker for Antidiuretic Hormone (ADH). Sex- and age-adjusted plasma copeptin concentration was 75%, 187%, and 207% higher in SIADH and normonatremic and hyponatremic CHF patients, respectively, than in healthy subjects. During an acute osmotic challenge, the plasma apelin to copeptin ratio decreased exponentially with natremia.

Copeptin, a 39-amino acid glycopeptide, is the C-terminal part of the prohormone of arginine vasopressin (AVP) or antidiuretic hormone (ADH).

It is a reliable surrogate marker for arginine vasopressin (AVP). Our data show that copeptin, a stable marker of ADH in plasma, is remarkably unchanged in normohydrated stable AN patients with extremely low BMI. Copeptin is suggested to be a more reliable biomarker for the stress level than cortisol, due to its higher stability (Lukaszyk & Malyszko, 2015). Copeptin is also a marker of acute hemodynamic stress, and has been reported to aid in the prognosis or diagnosis of several cardiac disorders such as acute coronary syndrome, stable coronary artery disease, congestive heart failure, and acute ischemic stroke. In addition, copeptin has been shown to be associated with increased risk of complications such as myocardial infarction, heart failure, diabetes mellitus and metabolic syndrome.
