METHOD FOR ANALYSING A BIOLOGICAL SAMPLE BY SUBTRACTION OF THE RESPECTIVE TOTAL AREAS OF A MASS SPECTRUM OF A SAMPLE TO BE ANALYSED AND OF A REFERENCE SPECTRUM

摘要

The present invention relates to a method for analysing a biological sample to be analysed, in which the following successive steps are carried out: a) a mass spectrum, preferably a MALDI-TOF mass spectrum, of said sample to be analysed, called spectrum to be analysed, is produced, b) at least one MALDI-TOF mass spectrum of a reference sample, called reference spectrum, is produced, and c) said spectrum to be analysed is compared with a said reference spectrum essentially by calculating the subtraction between the respective total areas of the spectrum to be analysed and of the reference spectrum.
