The aim of the present invention is to propose a novel method for spectral study of a biological fluid from an absorption spectrum of a sample of the biological fluid. The inventors have made an original use of spectroscopy in order to accurately determine the protein content of a biological sample, in particular for oxyhaemoglobin, methaemoglobin, bilirubin and the haem bound to serum albumin. Such a method can be used in a variety of applications concerning haem- or haemoprotein- related diseases, in particular diagnostic methods, treatment follow-up methods, methods for determining biomarkers or screening methods. Such a method is also advantageous for qualifying blood bags. |
