“Never underestimate the power of a simple tool.” - Craig Bruce

“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

Sample Collection is the Key

Not all samples are equal (even the best drug test is only as good as the specimen)

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

No pads No buffers No diluents

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

If the donor does not have to leave the facility Ideal for post-accident testing, pre-employment testing, random testing and reasonable suspicion testing

Only a 5 step collection process

Premium Oral Fluid Collector

Fast, easy and convenient sample collection

Minimal setup time

No “shy bladder”

Dual gender observation

75,400 websites have advice on beating urine-based screening - Google




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

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

Inadequate Recovery Δ9-THC in Collection Devices “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 fluidevaluation of sample collection devices." Journal of Analytical Toxicology 32(6): 393-401.

Premium Oral Fluid Collector

* Unaltered sample for maximum recovery * No pads, no buffers and no diluents to affect sample integrity * Glass is a better collection container vs. plastic for THC recovery and screening accuracy * Sample collection is fast and easy

Equally important is a device with a sample volume indicator -SAMHSA Proposed Revisions To Mandatory Guidelines for Federal Workplace Drug Testing Programs

No objective way to measure sample volume

Without an Indicator Collected sample volume can vary from 18-83%

Large variations are problematic to get quantitative results for drug recovery

Premium Oral Fluid Collector

� Accurate sample volumes are necessary to ensure accurate results � Easy to read fill line ensures sufficient sample volume � Decreases rejections for insufficient quantity

� Δ9-THC � Cocaine � Opiates � PCP � Amphetamine � Methamphetamine � MDMA (Ecstasy)

Oral Fluid Trends ďż˝ Oral fluid specimens


accounted for only 5%


of collected samples 2500000

in 2009 ďż˝ We project that by


2016 approximately 1500000

20% (over 20 million) of all


collected specimens


will be oral fluid 0 2003







Reproduced from A Five Year Analysis of Oral Fluid Drug Testing Results from a MRO Data Source, 2003-2007; Walsh, J.M., et al., 2008 Society of Forensic Toxicology National Meeting and data collected from the field in 9/09. Data is conservative and only shows one MRO source. 2009 data point from personal communication with J.M.Walsh.


Calculating Savings for Higher Positive Rates � 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.

� Easy to collect � Difficult to adulterate �Better indicator of recent drug use
