A crime laboratory’s DNA analysis unit analyzes bodily fluids and bodily fluid stains recovered as evidence in violent crimes. Examinations include the identification and characterization of blood, semen, saliva, and other bodily fluids using traditional serological techniques and related biochemical analysis. After the stain has been identified, it is characterized by DNA analysis using the restriction fragment length polymorphism (RFLP) or polymerase chain reaction (PCR) technique. The results of the analyses are compared with results obtained from known blood or saliva samples submitted from the victims or suspects.
