It is not clearly mentioned that this cutoff value is a delta — that is, a change in the plasma copeptin level at a plasma sodium level of 147 mmol per liter or more versus baseline. 2015-06-01 Copeptin and its role in the diagnosis of diabetes insipidus and the syndrome of inappropriate antidiuresis. Copeptin is secreted in an equimolar amount to arginine vasopressin (AVP) but can easily be measured in plasma or serum with a sandwich immunoassay. Copeptin and the Diagnosis of Diabetes Insipidus This study compared the indirect water-deprivation test with direct detection of plasma copeptin, a precursor of arginine vasopressin, in patients A Copeptin-Based Approach in the Diagnosis of Diabetes Insipidus.

Two new ways of using copeptin to discriminate between primary polydipsia and diabetes insipidus Testmetod för fritt testosteron i saliv hos nyfödda pojkar.

Copeptin as a predicitive marker for diabetes insipidus While diagnostic evaluation for polyuria-polydipsia syndrome usually takes place in the out-patient setting, the use of copeptin has also been evaluated as a predictive marker for the development of central DI following surgical procedures in the sellar region. Interpretation: Arginine-stimulated copeptin measurements are an innovative test for diabetes insipidus with high diagnostic accuracy, and could be a simplified, novel, and safe diagnostic approach to diabetes insipidus in clinical practice. Funding: Swiss National Science Foundation and University Hospital Basel. Whereas unstimulated basal copeptin measurement reliably diagnoses nephrogenic diabetes insipidus, two new tests using stimulated copeptin cutoff levels showed a high diagnostic accuracy in This study shows that arginine is a potent stimulus of the posterior pituitary gland and that arginine-stimulated copeptin measurements are an accurate test for diabetes insipidus. We found that a copeptin cutoff of 3·8 pM/L at 60 min after arginine infusion had an accuracy of 93% to diagnose diabetes insipidus in a dataset of patients with diabetes insipidus and primary polydipsia.
