Title:
ANALYSIS METHOD, SPECTROMETRY METHOD AND METHOD FOR IDENTIFYING ORGANISM
Document Type and Number:
WIPO Patent Application WO/2020/066795
Kind Code:
A1
Abstract:
An analysis method comprising: obtaining data corresponding to a mass spectrum that is obtained by subjecting a sample containing a microorganism to mass spectroscopy; and obtaining information relating to emm1 group A Streptococcus depending on the presence/absence of a peak or the peak size within a first range wherein the m/z value in the mass spectrum is from 10930 to 10945 inclusive.
