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.

However, this test is based on the induction of hypernatraemia and requires close … 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 … If the copeptin test was positive, defined as >10 pmol/L, they were treated with standard ACS care.If the copeptin assay showed copeptin levels <10 pmol/L, patients were discharged into ambulant 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 … Siemens. Copeptin was measured by the BRAHMS copeptin-us assay on the KRYPTOR Compact Plus system. The follow-up period was 90 days. Primary and secondary outcome measures: Copeptin, troponin, myoglobin and creatine kinase values.

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 Copeptin was measured in a blinded fashion in a single batch with a commercial sandwich immunoluminometric assay (LUMItest CT-proAVP; B.R.A.M.H.S. AG, Hennigsdorf/Berlin, Germany) as described previously (10, 16).

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. The clinical value of measuring serum/plasma copeptin is in the differential diagnosis of polyuria/polydipsia syndromes.

Today, the main use of copeptin is its role as stable surrogate marker for AVP concentrations in humans. 13 A prospective trial with 91 healthy volunteers undergoing a standardized test …

Interpretation of the copeptin diagnostic accuracy through these studies is not evident, ﬁrst, because ana-lysis comparisons are disrupted by the development of high-sensitivity cardiac troponin T and I assays and the availability of three commercial assays for copeptin (LUMItest, Copeptin Kryptor, Copeptin-us Kryptor). 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. Randomization listings were prepared with a probability of 1:1 and after that, randomized numbers were printed according to the results of the randomization.
