The Forensic Laboratory’s Biology, Chemistry, Firearm/Toolmark, and Latent Print Sections are accredited to the ISO/IEC 17025 standard by the ANSI National Accreditation Board (ANAB) through the forensic science testing laboratory accreditation program.
Accreditation to this program requires full compliance to the ISO/IEC 17025 standard, the supplemental accreditation requirements issued by ANAB, and the FBI Quality Assurance Standards for Forensic DNA Testing Laboratories.
The Biology Section performs presumptive testing for body fluids, human STR & YSTR DNA testing, physical comparison between evidentiary DNA profiles and known standards to determine identity, relatedness testing, and participates in the Combined DNA Index System (CODIS).
The Chemistry Section is comprised of three forensic disciplines performing drug, fire debris, and toxicology testing. The Chemistry Section identifies controlled substances and performs weight measurement, detects ignitable liquids and ignitable liquid residues, detects volatiles in biological fluids, quantifies ethanol in biological fluids, and detects ethanol in beverages.
The Firearm/Toolmarks Section performs examinations including: functionality testing on firearms, physical comparisons of bullets, cartridge cases, and shotshells to determine the number of firearms represented or identify common origin, caliber weapon type determination of evidence bullets, serial number restoration, ETrace entry, and entry of fired cartridge cases and firearms into the National Integrated Ballistic Information Network (NIBIN).
LATENT PRINTS SECTION
The Latent Prints Section processes evidence for the presence of latent prints, evaluates recovered prints to determine suitability for comparison, performs physical comparison between latent prints and known standards to determine identity, establishes the identity of unknown individuals, and participates in the Automated Fingerprint Identification System (AFIS) and the Next Generation Identification (NGI) system.
NORTHEAST OKLAHOMA REGIONAL NIBIN SITE
The Northeast Oklahoma Regional NIBIN site serves the participating communities in Northeast Oklahoma by providing ballistic evaluations and actionable investigative leads in a timely manner.
PUBLIC SAFETY ANALYSIS
The Public Safety Analysis Section collects and utilizes data and information to conduct tactical, strategic, and administrative analysis of crimes occurring within the City of Tulsa to determine trends and patterns, with recommended solutions.
