A Copeptin-Based Approach in the Diagnosis of Diabetes Insipidus Antnio Ribeiro-Oliveira, Jr., M.D., Ph.D., The indirect water-deprivation test is the current reference standard for the diagnosis of diabetes insipidus. However, it is technically cumbersome to administer, …

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). Whereas unstimulated basal copeptin measurement reliably diagnoses nephrogenic diabetes insipidus, two new tests using stimulated copeptin cutoff levels showed a high diagnostic accuracy in 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.

Although the water deprivation test determined the correct diagnosis with 76.6% accuracy, the copeptin test had a 97% rate of correct diagnoses. The investigators said that this allowed patients to receive faster treatment. Of the 144 patients that underwent both tests, 62 patients had forms of diabetes insipidus and 82 patients had polydipsia.

ferentiate nephrogenic diabetes insipidus from other polyuric states with nearly 100% sensitiv-ity and specificity. 4 However, a more challenging issue persisted — concern about the accuracy of stimulation tests that included copeptin mea-surements in distinguishing primary polydipsia from partial central diabetes insipidus.

Dersom fortsatt mistanke om diabetes insipidus og copeptin > 21 pmol/l er nefrogen årsak sannsynlig. Ved copeptin < 21 pmol/l bør videre utreding for sentral diabetes insipidus vurderes. A copeptin blood test reliably differentiated diabetes insipidus from polyuria-polydipsia, which is very important because the wrong diagnosis and treatment can be life-threatening in both The copeptin test, Dr. Robertson said, ''may be a reliable tool for differentiating nephrogenic diabetes insipidus from the other types of DI. Although the information on the reliability of this method is inadequate for full confidence, it may be easier to obtain and with proper improvements in the methods of interpretation may eventually prove to be a good alternative.'' Purpose of this study is to compare the overall diagnostic accuracy of the three following diagnostic test procedures in diabetes insipidus (central, nephrogenic) and primary polydipsia: a) classical water deprivation test alone, b) classical water deprivation test plus plasma copeptin cut-off levels, c) hypertonic saline infusion test plus plasma copeptin measurement. 2020-05-06 · Copeptin-based diagnosis of diabetes insipidus Refardt Julie ab, Christ-Crain Mirjam a Departments of Endocrinology ,Diabetology and Metabolism, University Hospital Basel Switzerland Fenske W, Refardt J, Chifu I, et al.A Copeptin-Based Approach in the Diagnosis of Diabetes Insipidus.
