GENDER AND RACE IDENTIFICATION FROM BODY FLUID TRACES USING SPECTROSCOPIC ANALYSIS

摘要

The present invention relates to a method of identifying gender and/or race of a subject using a body fluid stain from the subject. This method involves providing a sample containing a body fluid stain from the subject; providing a statistical model for determination of gender and/or race of a subject; subjecting the sample or an area of the sample containing the stain to a spectroscopic analysis to produce a spectroscopic signature for the sample; and applying the spectroscopic signature for the sample to the statistical model to ascertain gender and/or race of the subject. A method of establishing a statistical model for determination of gender and/or race of a subject using a body fluid stain from the subject is also disclosed.
