DNA analysis provides the ability to test items to make comparisons between the DNA profiles obtained.  The uniqueness of a DNA profile enables the lab to not only produce positive associations between individuals and evidence, but also eliminate individuals that could not have contributed to the DNA evidence. 

Additionally, the DNA laboratory is a designated CODIS (Combined DNA Index System) laboratory.  CODIS is the FBI's DNA database that links all 50 states to provide a means of comparing forensic casework profiles.  The database search may result in linking unsolved cases and can provide significant investigative leads.  For any questions regarding CODIS and/or CODIS investigative leads, email MECODIS@tarrantcountytx.gov.
