infolink offers new drug test

Los Angeles, CA, April 30, 2001—InfoLink Screening Services, Inc. has announced it will add a

new drug-testing technology that relies on hair analysis to the urine testing products and services it currently

offers. The service is made available through an alliance with Psychemedics Corporation covering special

services and rates. Psychemedics pioneered development of the new system, patented it and is obtaining

FDA clearance for each of the drug tests it employs. Psychemedics’ hair test screens for five categories of

drugs of abuse including: marijuana, cocaine (as well as crack cocaine), opiates (heroin), methamphetamine

(speed, uppers and ecstasy), and PCP (angel dust). Additional tests are also under development.

“InfoLink recognizes drug abuse as a primary threat to the environment of safety and productivity that

good employers strive to create,” states Barry Nadell, President and CEO of InfoLink. “We are please to add

Psychemedics’ hair-testing capabilities to our drug-testing arsenal which includes both on-site and off-site

urine testing as well as education services for employers.”

Psychemedics claims several advantages for its system over urinalysis, the most common

alternative. Collection of hair samples, for example, is non-intrusive and can easily be done in-house whereas

urine testing is often done under the supervision of off-site laboratories.

The processing time for hair samples is faster than for urine tests. Most negative results are available

within 24 hours with positive test results confirmed within 2-3 days. (All initial positives are confirmed using

GC/MS/MS or LC/MS/MS.) InfoLink clients are notified by e-mail when the result of the hair

test is available. Final reports are obtained by clients calling an 800 number, receiving a fax, or by reviewing

the report in InfoLink’s secure Web site.

Perhaps the most exciting benefits offered by hair-based analysis are that it tracks a longer personal

history for each individual and claims a substantially greater ability to detect drug use. Urine testing can

normally detect drug use for only three days after ingestion, while hair testing will detect drug use during the

previous ninety days.

Psychemedics has documented drug detection rates ranging from five to ten times greater than urine

testing depending on the drugs involved. In one study conducted by a large manufacturing company, samples

from 774 job applicants were tested using both urine testing and Psychemedics’ hair analysis. The

Psychemedics test detected sixteen times more cocaine users than urine tests on the same applicants and six

times as many total drug users.

As the detection abilities of hair-based testing apply to a longer time period, short-term abstention will

not elude the test as it does for urinalysis. Likewise, hair testing is not susceptible to substitution or

adulteration of samples as urinalysis can be. Employees and schools throughout the US report that when those

eligible for testing learn that hair testing (unlike urinalysis) cannot be foiled, the hair test serves as a very

significant and cost-effective deterrent.
