Welcome to the DuPage County Forensic Science Center


About our Laboratory

The DuPage County Crime Forensic Science Center (FSC) is located in Wheaton, Illinois, approximately 30 miles west of Chicago. Since May 1st, 1971, the citizens of DuPage County have benefited from the laboratory services provided by the Sheriff's FSC, which are made available to all law enforcement agencies in the county.  In 2006, the DuPage County Sheriff’s Office earned the prestigious international ISO 17025 certification for forensic testing laboratories through the American Society of Crime Laboratory Directors – Laboratory Accreditation Board (ASCLD/LAB).


Our Mission

The mission of the DuPage County FSC is to provide quality and timely forensic science services to the criminal justice system of DuPage County.  The laboratory has three sections:  Forensic Chemistry and Microscopy, Criminalistics and Forensic Biology/DNA which offer analysis in the disciplines of Drug Chemistry, Trace Chemistry, Latent Prints (not currently available) and Forensic Biology/DNA.


DuPage County FSC Awarded Renewal of ASCLD/LAB-International Accreditation

In November 2015, after an intensive on-site assessment the ASCLD/LAB Board voted to grant another four-year cycle of ASCLD/LAB-International accreditation for forensic testing.

Advisory -  Standing Policy on Submission Restrictions

This bulletin sets forth policies governing the submission of certain types of evidence to the DuPage County Forensic Science Center and the analyses that may or may not be conducted.


Work Volume

In 2015 the laboratory generated 2,022 assignments: 


• Drug Chemistry 1,475  
• Impression Evidence (Latent Prints, Shoe & Tire Impressions) - Outsourced 13  
• Forensic Biology / DNA 429  
• CODIS 59  
• Trace Chemistry 11  
• Cancelled Testing Report 27  
• Supplemental 8  


Laboratory Sections

The Forensic Chemistry and Microscopy Section comprises Drug Chemistry and Trace Chemistry.  Drug chemistry analyzes evidence suspected to contain cannabis or a controlled substance.  Trace chemistry includes analysis of the following types of evidence:  hairs, fibers, glass, paint, wood, explosives, fire debris, flammable liquids and motor vehicle lamps.


At this time the laboratory is unable to provide latent print services and is in the process of training an examiner in latent print analysis.  Latent Prints analysis involves the examination of evidence to determine if finger, palm, and footprints found at a crime scene can be identified as belonging to a suspect.  


The Forensic Biology/DNA Section comprises Forensic Biology and DNA.  Forensic biology involves the screening of items for bodily fluids and preparing those samples for DNA analysis. DNA refers to the analysis of samples in order to obtain a human DNA profile.
