The serology and DNA section examines evidentiary items for body fluids and evidence that may not be readily visible to the naked eye. When analyzing items for body fluids, such as blood, semen and saliva, the scientist must locate the sample, then identify its origin. The scientist can offer an opinion regarding the association between the sample and the person.

The Serology and DNA Laboratory processes different types of samples, including blood, semen, saliva, hairs and fibers and other substances.

DNA Testing Guidelines

Cases and the subsequent items submitted to the MVRCL for DNA analyses will be reviewed by forensic scientists for completeness prior to DNA testing.

In order to comply with federal statutes:

Cases, specifically the synopsis, submitted to the MVRCL for DNA analyses will be reviewed for information that supports a link between the evidence item(s) from the crime scene and a putative perpetrator(s).

The failure to provide relevant case information may prevent or delay the start of DNA analysis on some or all items submitted.  It is the agency’s responsibility to supply documentation at the time of submission.  Space for details about items and how they relate to the crime scene is provided on the MVRCL submission sheet.

An item taken directly from a suspect is not considered a forensic sample.  DNA profiles resulting from drug paraphernalia and firearms recovered from the suspect’s person, residence, or personal property are not permissible for CODIS entry and thus cannot be searched in CODIS to potentially develop an association with another CODIS sample.  As a result, DNA testing will only involve direct comparisons between suspect standard(s) and the evidence profile(s).

               In cases involving items of possession, DNA analysis cannot be performed without DNA standards. 

Items that belong to and/or handled frequently by a victim(s) (i.e. vehicle operator and common passengers) will require DNA standards from the victim(s) for elimination purposes.

The failure to provide necessary DNA standards at the time of submission may prevent or delay DNA analysis on some or all items submitted.

Failure to supply DNA standards from suspects, elimination standards, or information documenting a link between evidence items and the crime scene will result in a report requesting the missing information or standards and notification of items being retained with no testing being conducted.

Cases submitted with supporting documentation as well as all standards needed are immediately put into process for DNA.

For additional information regarding the federal statutes referenced above, please see sections 4.2.1.3 and 4.2.1.8 of the NDIS Operation Procedures (https://www.fbi.gov/file-repository/ndis-operational-procedures-manual.pdf)
