Body fluid analysis

Body fluid analysis


Conducting body fluid analysis in order to determine the presence or absence, identity and distribution of particular body fluids is key to the investigation of crimes against the person e.g. rape, assault or murder. The body fluids encountered in these types of cases are usually blood, semen and saliva and in some cases given the severity of the crime urine and faeces.


The correct identification of traces of these fluids at a crime scene or on clothing may be vital to a criminal investigation. The presence or absence of a particular body fluid on clothing, possible weapons, swabs or other items related to a crime scene, may assist a forensic biologist in determining what may have occurred at a crime scene and in identifying the persons that were or were not involved in the perpetration of the crime.
