Diagnostic tool detecting the degradation status of Von Willebrand Factor multimers

Abstract

A method in which the cleavage profile and size distribution of von Willebrand factor (VWF) multimers is analyzed, includes: providing a sample medium of human body fluids comprising a plurality of VWF multimers of different size; enrichment or purification of the VWF multimers by cryoprecipitation or chromatography to obtain a separated preparation of the VWF multimers from said sample medium; exposing the separated preparation of VWF multimers to a light source to produce signals obtained by vibrational spectroscopy; detecting said signals; transformation by mathematical alogrithms; generation of patterns based on computing of data of original resonance spectra and determining the cleavage profile and the size distribution of said separated VWF multimers by chemometrics; and acquisition of a databank obtained from healthy individuals for identifying subjects at risk of developing at least one of the following diseases: sepsis, coagulopathy, thrombotic disease, infection, and inflammation.
