The Crime Lab makes a difference by ... testing toxicology

In honor of National Forensic Science Week, the Orange County Crime Lab wants to educate the public on the many ways our work impacts the county and makes a difference in the life of the citizens we serve.


With impaired driving becoming an increasing problem on Orange County’s roadways, the Crime Lab last year launched an initiative to test all drivers arrested on suspicion of DUI, regardless of the results of the breath alcohol test.


They provide drug and alcohol testing on driving under the influence samples; with more than 24 percent of Orange County DUI blood samples testing positive for THC - the psychoactive ingredient found in marijuana. The laboratory maintains, calibrates, and trains all operators for all evidential breath alcohol testing instruments, providing the highest quality results for criminal court trials.


However, their work goes well beyond traffic-related cases.  


The laboratory also provides testing in suspected drug-facilitated sexual assault and death investigations with state of the art technology for more than 325 drugs including over the counter medications, prescription drugs, and illicit controlled substances. 


They aid investigators in assessing suspected clandestine drug manufacturer and conduct all chemical analysis on narcotics throughout the county; anything from the testing of methamphetamine, heroin, cocaine, fentanyl and counterfeit pills. The Orange County Crime Lab makes a difference in your life by providing advanced, comprehensive drug and alcohol testing of the highest quality.
