The secretion of both peptides is stimulated by similar physiological processes, such as osmotic stimulation, hypovolemia, or stress. AVP is difficult to measure due to complex preanalytical requirements and due to technical difficulties. In the last years, copeptin was found to be a stable, sensitive, and simple to measure surrogate marker of AVP release. Different immunoassays exist to measure copeptin. The 2 assays which have most often be used in clinical studies are the original sandwich immunoluminometric assay and its automated immunofluorescent successor. In addition, various enzyme-linked immunosorbent assay have been developed. With the availability of the copeptin assay, the differential diagnosis of diabetes insipidus was recently revisited. The goal for this article is therefore to first review the physiology of copeptin, and second to describe its use as marker for the differential diagnosis of vasopressin-dependent fluid disorders, mainly diabetes insipidus but also hyper- and hyponatremia. Furthermore, we highlight the role of copeptin as prognostic marker in other acute and chronic diseases.<\/jats:p>","DOI":"10.1210\/clinem\/dgac070","type":"journal-article","created":{"date-parts":[[2022,2,9]],"date-time":"2022-02-09T03:37:50Z","timestamp":1644377870000},"page":"1727-1738","source":"Crossref","is-referenced-by-count":52,"title":["Approach to the Patient: \u201cUtility of the Copeptin Assay\u201d"],"prefix":"10.1210","volume":"107","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6336-0965","authenticated-orcid":false,"given":"Mirjam","family":"Christ-Crain","sequence":"first","affiliation":[{"name":"Department of Endocrinology, Diabetes and Metabolism, University Hospital Basel, 4031 Basel, Switzerland"},{"name":"Department of Clinical Research, University Hospital Basel, 4031 Basel, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3040-4685","authenticated-orcid":false,"given":"Julie","family":"Refardt","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, Diabetes and Metabolism, University Hospital Basel, 4031 Basel, Switzerland"},{"name":"Department of Clinical Research, University Hospital Basel, 4031 Basel, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8305-2700","authenticated-orcid":false,"given":"Bettina","family":"Winzeler","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, Diabetes and Metabolism, University Hospital Basel, 4031 Basel, Switzerland"},{"name":"Department of Clinical Research, University Hospital Basel, 4031 Basel, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"80","published-online":{"date-parts":[[2022,2,8]]},"reference":[{"issue":"1","key":"2022051722350210600_CIT0001","doi-asserted-by":"crossref","first-page":"98","DOI":"10.1093\/clinchem\/45.1.98","article-title":"Improved extraction procedure and RIA for determination of arginine8-vasopressin in plasma: role of premeasurement sample treatment and reference values in children","volume":"45","author":"Kluge","year":"1999","journal-title":"Clin Chem."},{"issue":"4","key":"2022051722350210600_CIT0002","doi-asserted-by":"crossref","first-page":"1046","DOI":"10.1210\/jc.2010-2499","article-title":"Correlation of plasma copeptin and vasopressin concentrations in hypo-, iso-, and hyperosmolar States","volume":"96","author":"Balanescu","year":"2011","journal-title":"J Clin Endocrinol Metab."},{"issue":"1","key":"2022051722350210600_CIT0003","doi-asserted-by":"crossref","first-page":"112","DOI":"10.1373\/clinchem.2005.060038","article-title":"Assay for the measurement of copeptin, a stable peptide derived from the precursor of vasopressin","volume":"52","author":"Morgenthaler","year":"2006","journal-title":"Clin Chem."},{"issue":"5847","key":"2022051722350210600_CIT0004","doi-asserted-by":"crossref","first-page":"299","DOI":"10.1038\/295299a0","article-title":"Nucleotide sequence of cloned cDNA encoding bovine arginine vasopressin-neurophysin II precursor","volume":"295","author":"Land","year":"1982","journal-title":"Nature."},{"issue":"3","key":"2022051722350210600_CIT0005","doi-asserted-by":"crossref","first-page":"320","DOI":"10.1111\/j.1399-3011.1986.tb01827.x","article-title":"Ontogeny of bovine neurohypophysial hormone precursors.
