Copeptin has now replaced the measurement of ADH (anti-diruretic hormone). Copeptin is the C-terminal glycoprotein moiety of pre-provassopressin and is released in the same amount as AVP. Morning samples after 8 hour fast (without water restriction) are recommended unless otherwise stated by clinician. Copeptin proAVP shows a significant correlation with vasopressin, it is stable ex vivo and performs precise measurement. In addition, it is easy to manage with results available in less than one hour. Copeptin is a reliable surrogate marker of vasopressin (AVP/ADH) Copeptin helps to rule out AMI with Troponin. Note: Copeptin (also known as Copeptin proAVP or Copeptin AVP) and arginine vasopressin (AVP) are derived from the same precursor peptide.

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. Copeptin proAVP (CT-proAVP) Ein neuer Biomarker bei der Diagnose von Störungen des Wasserhaushalts Biologische Grundlagen ADH ist ein Hormon der Neurohypophyse, das im Hypo - thalamus synthetisiert und in den sekretorischen Ves-ikeln des Hypophysenhinterlappens (HHL) gespeichert und bei Bedarf sezerniert wird. Eine erhöhte Plasmaos- Copeptin can therefore be used as a surrogate for ADH concentration. It has the advantage of having a much longer plasma half-life than ADH, greater stability at room temperature and therefore is less prone to preanalytical errors. As a result, RPAH has replaced its ADH assay with the Copeptin assay.

In this Review, Christ-Crain and Fenske describe the use of copeptin CPAVP : Patient Preparation: For water-deprived testing, have the patient fast and thirst for at least 8 hours (no liquids, including water, are allowed) Collection Container/Tube: Lavender top (EDTA) Submission Container/Tube: Plastic screw-top vial Specimen Volume: 0.5 mL Collection Information: Centrifuge and aliquot plasma into plastic vial. Beim Transport entstehen äquimolar die Moleküle ADH, Neurophysin II und Copeptin. ADH wird im Hypophysenhinterlappen gespeichert. Die Ausschüttung von ADH wird durch 2 Mechanismen stimuliert: Osmorezeptoren im Hypothalamus reagieren auf einen Anstieg der Plasmaosmolalität ( Osmolalität ), Barorezeptoren im rechten Vorhof und im Aortenbogen auf Volumenmangel. Copeptin (also known as CT-proAVP) is a 39-amino acid-long peptide derived from the C-terminus of pre-pro-hormone of arginine vasopressin, neurophysin II and copeptin. Arginine vasopressin (AVP), also known as the antidiuretic hormone (ADH), is involved in multiple cardiovascular and renal pathways and abnormal level of AVP are associated with various diseases.

It can therefore be reliably used as a surrogate marker for ADH. 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. 12,15,16 In previous studies, we Copeptin has now replaced the measurement of ADH (anti-diruretic hormone). Copeptin is the C-terminal glycoprotein moiety of pre-provassopressin and is released in the same amount as AVP. Morning samples after 8 hour fast (without water restriction) are recommended unless otherwise stated by clinician. Copeptin is a more stable surrogate biomarker of AVP release. The clinical utility of copeptin of differentiating polyuria and water balance disorders has been demonstrated in a number of studies, when used in conjunction with osmolality and hydration status. Background: Copeptin, the C-terminal moiety of provasopressin, is cosecreted with vasopressin.

La vasopressina (AVP), conosciuta anche come ormone antidiuretico (ADH), svolge due funzioni primarie: trattiene l’acqua all’interno del corpo e ha un effetto costrittivo sui vasi sanguigni. È coinvolta in svariate patologie e condizioni ed ha un importante valore diagnostico.
