Specimens from positive cases are stored for 5 years and negative cases are stored for 2 years. This allows for independent testing by an outside laboratory if there are questions regarding the test results. A national proficiency testing program is also administered and maintained by the toxicology laboratory. This unique program allows the participants to evaluate their professional development and technical currency on an interlaboratory basis and to assess their methods in the presence and absence of postmortem interfering substances. Analysis of specimens is conducted using state of the art equipment.
Research is performed using the most advanced equipment available in the world.
