1 Jun 2019 In contrast with arginine vasopressin (AVP), copeptin exhibits higher For blood tests, 12 ml of venous blood sample was collected from the 


In conclusion, the accuracy of copeptin is suboptimal for use in diagnostic algorithms of AAS. In particular, a negative copeptin test should not be used to conclusively rule-out AAS without CTA. After exclusion of AAS, presence of high copeptin levels defines a heterogeneous group of acute patients at higher risk of death.

Arginine-stimulated copeptin measurements - a new test for diabetes insipidus Bettina Winzeler 1, Nicole Nigro-Cesana 1, Julie Refardt 1, Deborah R Vogt 2, Cornelia Imber 1, Benedict Morin 1, Milica Popovic 1, Michelle Steinmetz 1, Clara Sailer 1, Gabor Szinnai 3, Irina Chifu 4, Martin Fassnacht 5 & Mirjam Christ-Crain 1 2008-3-6 · As a diagnostic marker, copeptin was evaluated in patients with diabetes insipidus – for example, after pituitary surgery. In these patients copeptin had a superior diagnostic accuracy to detect an insufficient activity of the posterior pituitary, offering an alternative to the laborious and ambiguous water-deprivation test . • at 60 min following an arginine stimulation test, a copeptin level ≥3.8 pmol/L identified primary polydipsia and a copeptin level <3.8 pmol/L identified complete or partial central diabetes insipidus, with 93% sensitivity and 92% specificity Test Name Copeptin Test Code SACOP Specimen Type.

Clin. 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). Although the water-deprivation test is considered the reference standard for the evaluation of DI, measurement of saline stimulated copeptin was shown to be more accurate than the water-deprivation test.(2) In this indirect water deprivation test with a cutoff of 4.9 pmol/L or less indicated central DI while a concentration greater than 4.9 pmol/L indicated primary polydipsia.

Arginine-stimulated copeptin measurements … A blood test for copeptin, a precursor of antidiuretic hormone (ADH, vasopressin), differentiates between "harmless" polydipsia-polyuria and diabetes insipidus more quickly and accurately than a 2021-2-28 · Patients were randomly divided into one of 2 test protocols: 1. Copeptin combined with hs-cTnT group, 2. cTnI group. Randomization was performed without any stratification.

Both peptides, copeptin and AVP, show a high correlation. Accordingly, copeptin mirrors the amount of AVP in the circulation and its measurement provides an attractive marker in the differential diagnosis of diabetes insipidus. Bettina Winzeler and colleagues1 investigated whether copeptin measurement after an arginine stimulation test could be a tool to unravel the differential diagnosis of polyuria-polydipsia syndrome. We caution that the high sensitivity and specificity of the test could have partly been due to the selection of included patients. In conclusion, the accuracy of copeptin is suboptimal for use in diagnostic algorithms of AAS. In particular, a negative copeptin test should not be used to conclusively rule-out AAS without CTA. After exclusion of AAS, presence of high copeptin levels defines a heterogeneous group of acute patients at higher risk of death. Copeptin. Median copeptin concentration in the study population was 132 pmol/L (IQR 39.05–372.38 pmol/L, range 3.4–2373 pmol/L).

Copeptin test

Copeptin concentrations obtained in the process of a water deprivation test can be difficult to interpret because of variation in water deprivation protocols. Patients with psychogenic polydipsia will either have a normal response to water deprivation or, in long-standing cases, show a pattern suggestive of mild nephrogenic DI. 2010-04-22 · Copeptin was associated with IGFBP-1 (Spearman rank correlation test, r = 0.53; P < 0.001). During follow-up there were 138 cardiovascular events (cardiovascular death, myocardial infarction, and stroke).
