Diagnostic method for disorders using copeptin
The use of copeptin as diagnostic marker for the determination of the release of vasopressin, especially in connection with disorders associated with non-physiological alterations of vasopressin release from the neurohypophysis, especially for detection and early detection, diagnosing and monitoring of the course of cardiovascular diseases, renal and pulmonary diseases as well as shock, including septic shock, sepsis and diseases/disorders of the central nervous system and neurodegenerative diseases.
1. A kit for determining the amount of copeptin in a bodily fluid sample, wherein said kit comprises:
(a) a first antibody that specifically binds a first epitope on a first peptide consisting of amino acids 132-147 of SEQ ID NO.:4,
(b) a second antibody that specifically binds to a second epitope on a second peptide consisting of amino acids 149-164 of SEQ ID NO.: 4; wherein at least one of said first or second antibodies carries a detectable label; and
(c) a calibrator peptide consisting of the amino acid sequence of SEQ ID NO.: 3.
2. The kit of claim 1 , wherein said bodily fluid sample is blood, plasma or serum.
