DNA Data Bank

About

The Virginia DNA Data Bank Section receives, accessions and processes samples from convicted offenders and certain arrestees. Analysts in the Data Bank conduct DNA analysis on these samples.  DNA profiles obtained from the offender/arrestee samples are entered into the Combined DNA Index System (CODIS) and searched for possible matches to unknown DNA profiles from evidence collected at crime scenes. These searches can be conducted at the state and national levels.  The Virginia DNA Data Bank contains over 400,000 offender DNA profiles.
