Serology/DNA

The Serology/DNA section examines physical evidence collected through medical-legal and/or crime scene investigations to determine the presence of body fluids such as blood, semen, and saliva.  The analysts compare the DNA profiles obtained from evidence body fluid stains with known DNA profiles of submitted known standard samples to identify likely sources of the unknown body fluid stains.

The section participates in the Combined DNA Index System (CODIS) allowing for the exchange of forensic DNA evidence across multiple jurisdictions.
