Validation of a Confirmatory Proteomic Mass Spectrometry Body Fluid Assay
December 2023
While forensic DNA analysis can identify an individual(s) at a crime scene, it cannot identify the biological source from which that DNA was obtained – e.g. blood, saliva, or semen. Identification of the biological source of DNA can provide important contextual information for forensic investigations as well as evidence in court. Nearly all current methods used for body fluid identification are presumptive. Here we present a new proteomic mass spectrometry method for the confirmatory identification of blood, saliva, and semen.
