Copeptin is the C terminal peptide of proAVP and is co-secreted on an equimolar basis with AVP from the posterior pituitary. Arginine vasopressin (AVP), also known as antidiuretic hormone (ADH), is a hypothalamic polypeptide that is transported along the axons of the synthesizing neurons into the posterior pituitary gland.


Normal range of copeptin. The normal range for copeptin is now well defined. Data from the first study with healthy volunteers, which was carried out without prior fluid control or fasting, indicated a median copeptin plasma concentration of 4.2 pmol.L −1 (range, 1–13.8 pmol·L −1) 46.

Males show slightly higher copeptin values with minimal difference in median values; age or circadian rhythm does not seem to interfere nor does food intake or menstrual cycle. Copeptin plasma concentration in 359 healthy individuals were (median, range) 4.2 pmol/liter (1–13.8 pmol/liter). The 97.5th percentile was 11.25 pmol/liter, and the 2.5th percentile was 1.7 pmol/liter. Of all 359 tested volunteers, only nine (2.5%) had a plasma copeptin concentration below the detection limit of the assay of 1.7 pmol/liter. Normal range of copeptin. The normal range for copeptin is now well defined.

Median follow-up time was 11.5 years (range 11.0 to 12.0 years). Copeptin was elevated (that is, above the 97.5 percentile in healthy individuals) (22/693) for patients with normal copeptin. Aims To test the utility of a single copeptin determination at presentation to the emergency department (ED) as a short-term prognosis marker in patients with non-ST-elevation acute coronary syndrome (NSTEACS). To compare the results with those achieved with conventional troponin.

Ann Neurol 2009;66:799-808. Distribution of copeptin is shown in Supplementary Figure S1, with a median value of 6.4 (3.8 to 11.0) pmol/l, and higher values in males than females. Subjects with higher copeptin had higher systolic and diastolic blood pressure, a higher body mass index as well as higher total kidney volume (TKV) and lower eGFR.

May 4, 2018 As such, we chose to use copeptin as a surrogate marker for AVP. Serum potassium and magnesium levels were maintained within the normal range. The three control patients had a mean CSF copeptin level of only 253&nb

As a Control Group, 30 healthy individuals with normal physical examination results were included. In terms of blood copeptin levels, the result was 0.48 ± 0.27 ng/ml for the Control Group, 1.03 ± 0.56 ng/ml for Group 1, and 0.50 ± 0.32 ng/ml for Group 2. Moreover, copeptin has been suggested as a unifying factor of the main components of the metabolic syndrome [17] and elevated levels of copeptin strongly predict the subsequent development of diabetes mellitus .

Copeptin normal range

Indeed, recent studies have found promise in its use in managing sepsis as copeptin levels were found to distinguish normal controls from septic patients, and septic patients from septic shock patients [44]. It may also hold promise as a cardiology biomarker in conjunction with troponin for acute myocardial infarction rule out [45,46].

19 male and female subjects, aged 18–53 years (mean 25.8 years), participated in the study.

The[18] potential connection between copeptin or AVP levels and cognitive impairment has not been studiedpreviously . CPAVP : Arginine vasopressin (AVP) and copeptin (also known as copeptin proAVP or copeptin AVP) are derived from the same precursor peptide. Copeptin has been proposed as a more stable, potentially superior, surrogate marker of AVP in the assessment of water balance disorders.
