Oral Fluid Drug Testing Program

Oral fluid (or saliva) collection is rapid, non-invasive, and simple. Oral fluid contains the active/impairing drug which likely represents recent drug use. We are the first state to offer a comprehensive Oral Fluid Drug Testing program at the State Crime Laboratory level. It is two-fold: (1) screening at the roadside and (2) evidentiary confirmation oral fluid drug testing at ADFS.

Excerpt from "Using Oral Fluid to Detect Drugs. Infographics. Sponsored by AAA. 2020."

First, we have validated and approved three “roadside” oral fluid drug screening devices that law enforcement can use during a DUI stop or crash to identify drug use. Field screening devices test for marijuana, cocaine, methamphetamine, amphetamine, opioids, and benzodiazepines. The devices are analogous to PBTs for alcohol and should be used to establish probable cause. They display “positive” or “negative” and should be administered after standardized field sobriety tests to confirm suspicion of drug use. This information can also be used to assist with obtaining a search warrant to collect a confirmation specimen such as blood (or oral fluid). It is the responsibility of the law enforcement agency to purchase, maintain, and seek adequate training for these devices.

Secondly, we now offer laboratory testing of oral fluid samples at ADFS. After an arrest, an evidentiary confirmation oral fluid specimen should be collected in an appropriate collection device/tube provided by ADFS. The Toxicology Section will test the oral fluid sample and issue a report of our findings. We test for ~30 drugs of abuse and therapeutic drugs commonly found in driving cases. It is considered best practice to collect both blood and oral fluid. In some circumstances, testing both specimens will provide a more complete picture of recent drug use. The first oral fluid case was submitted to the laboratory in August 2018. Newly distributed DUI biological specimens kits (BSKits) containing one Quantisal oral fluid device and two blood tubes have been distributed throughout the state. The kits no longer contain a urine container. As of June 2022, we have received over ~1300 oral fluid cases.
