ORAL FLUID DRUG TESTING: A SIMPLE SOLUTION FOR A COMPLEX WORLD
“WOLFE WORDS” Adulterated – made impure by
adding extraneous, improper, or inferior ingredients
Neat Sample – a sample obtained by expectorating (spitting) rather than through a medium such as a pad or
buffer
Metabolite – a product of metabolic action
Substituted – any sample not produced by the donor
A “neat” oral fluid sample is the best method of collection for the highest percentage of drug recovery. -SAMHSA Proposed Revisions to Mandatory Guidelines for Federal Workplace Drug Testing Programs
Sample Collection is the Key Not all samples are equal (even the best drug test is only as good as the specimen)
No buffers No diluents
No pads
Less non-productive time for donors and collectors
Ideal for onsite
collecting Totally
observable
No donor privacy
concerns Less set-up
time
Dual gender observations
No “shy bladder”
issues
Saves time and productivity
Reduces the likelihood of possible
adulteration/substitution
Ideal for post-accident testing, pre-employment testing, random testing
and reasonable suspicion testing
Only a 5 step collection process
If the donor does not have
to leave the facility
Fast, easy and convenient sample collection

Oral fluid drug testing can detect current drug use. The window of detection in
oral fluid drug testing is 12-24 hours.
Oral Fluid is great for:
For Cause Post Accident
Random Tests
Return to Duty
Pre-Employment
Marijuana is the most commonly used illicit drug
• is the primary compound and psychoactive ingredient in marijuana
• (parent) is the most prevalent marijuana compound in saliva
• becomes very sticky when warm and tends to cling to porous surfaces
• is the most difficult drug to recover in oral fluid testing
Δ9-THC
“The recovery of Δ9-THC from devices with absorbing components is a problem. The recovery of Δ9-THC is not as good as that of other analytes due to the absorption of Δ9 THC to the plastic and the absorptive compounds of the device.”
*Langel, K., C. Engblom, et al. (2008). "Drug testing in oral fluid-evaluation of sample collection devices." Journal of Analytical Toxicology 32(6): 393-401.
Inadequate Recovery Δ9-THC in Collection Devices
* Sample collection is fast and easy
* No pads, no buffers and no diluents to affect sample integrity
* Unaltered sample for maximum recovery
* Glass is a better collection container vs. plastic for THC recovery and screening accuracy
Premium Oral Fluid Collector
Equally important is a device with a sample volume indicator
-SAMHSA Proposed Revisions To Mandatory Guidelines for Federal Workplace Drug Testing Programs
Without an
Indicator
No objective way to
measure sample volume
Large variations are problematic
to get quantitative results for
drug recovery
Collected sample volume can vary from
18-83%
� Accurate sample volumes are necessary to ensure accurate results
� Easy to read fill line ensures sufficient sample volume
� Decreases rejections for insufficient quantity
Premium Oral Fluid Collector
� Δ9-THC � Cocaine � Opiates � PCP � Amphetamine � Methamphetamine � MDMA (Ecstasy)
� Oral fluid specimens
accounted for only 5%
of collected samples
in 2009
�We project that by
2016 approximately
20% (over 20
million) of all
collected specimens
will be oral fluid
samples

Data is conservative and only shows one MRO source. 2009 data point from personal communication with J.M.Walsh.

Oral Fluid Trends
� 75%+ of drug users have jobs �There are between 10 million and 12 million drug users in the
workplace � It is estimated businesses lose between $129 billion and $180
billion per year due to productivity losses to drug use �Drug users are 33% less productive than their co-workers, and
on average cost their employers between $7,000 and $15,000 annually U.S. Department of Labor, Occupational Safety & Health Administration website; Safety and Health Topics, Workplace Substance Abuse.
Calculating Savings for Higher Positive Rates
� Easy to collect
� Difficult to adulterate
�Better indicator of recent drug use
