Method for body fluid identification

Abstract

Crime scene investigators need to identify biological tissue or fluid types. Such analysis is typically done using conventional chemical, serological and enzymatic tests to identify the body fluid or tissue, however, these tests can be unreliable and often do not meet the specificity and sensitivity required for forensic analysis. The present invention provides a method for accurately identifying circulatory blood, saliva, spermatozoa, seminal fluid, menstrual fluid and vaginal material by detection of specific RNA sequences. In particular, the invention provides a method for determining the type of a biological sample, comprising the steps of detecting RNA from the sample associated with any one or more of HBD, SLC4A1, GYPA, FDCSP, HTN3, STATH, PRM1, TNP1, PRM2, KLK2, MSMB, TGM4, MMP10, STC1, MMP3, MMP11, CYP2B7P, Lactobacillus gasseri (L.gass) and Lactobacillus crispatus {L.crisp) and determining whether the sample is circulatory blood, saliva, spermatozoa, seminal fluid, menstrual fluid or vaginal material.
