While DNA can be obtained from bodily fluids and allows the identification of a person, it doesn’t allow the source of the bodily fluid to be determined. For example, it doesn’t allow you to differentiate blood from menstrual blood.

Rachel Fleming, from Environmental Science and Research, has developed a method of identifying the specific source of bodily fluid found in stains. She is now working on techniques to determine the age of stains. This will allow more specific information to be gathered in crime scene investigations.
