Copeptin (CT-proAVP) is a 39-aminoacid glycopeptide—the C-terminal part of Copeptin is a reasonable surrogate marker for AVP and measurement of
Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory Reference Values Describes reference intervals and additional Copeptin and vasopressin (AVP, ADH) are released from the same precursor hormone in equimolar amounts into the bloodstream, hence Copeptin can be used as a surrogate marker for vasopressin. B·R·A·H·M·S Copeptin proAVP KRYPTOR is indicated in conjunction with Troponin as an aid in ruling out acute myocardial infarction in patients presenting with chest pain or equivalent symptoms of The extraordinary stability of Copeptin eases lab logistics: The Thermo Scientific B·R·A·H·M·S Copeptin proAVP KRYPTOR assay reliably replaces the measurement of vasopressin and opens the possibility to achieve the full diagnostic potential of this hormone in rule-out of myocardial infarction (AMI) and water-balance disorders. AVP/Copeptin release from anterior pituitary gland (blue dots pathway) When released by the anterior pituitary gland, the precursor peptide is synthesized and processed in the parvocellular neurons of the hypothalamus, an area where releasing hormones, such as corticotropin-releasing hormone (CRH), are also produced. Recently, copeptin, a 39-amino acid glycopeptide that comprises the C-terminal part of the AVP precursor (CT-proAVP), was found to be a stable and sensitive surrogate marker for AVP release, analogous to C-peptide for insulin.

In contrast to AVP, copeptin is very stable in the 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).
Copeptin, a 39-amino acid glycopeptide, is the C-terminal part of the prohormone of arginine vasopressin (AVP) or antidiuretic hormone (ADH).

The Brahms CT-proAVP assay measures the C-terminal precursor fragment of arginine vasopressin (AVP), otherwise known as copeptin. Copeptin is released on an equimolar basis with AVP and therefore measurement of serum/plasma copeptin provides a surrogate measure of AVP concentrations.

Arginine vasopressin (AVP) and copeptin (also known as copeptin proAVP or copeptin AVP) are derived from the same precursor peptide. Copeptin has been proposed as a more stable, potentially superior, surrogate marker of AVP in the assessment of water balance disorders. Unlike AVP, copeptin is stable in plasma.
