Psychemedics' patented hair analysis technology is
a proven drug testing method which not only detects
if drugs of abuse have been used, but also provides
information on the quantity and historic pattern of
individual drug use. This type of information is not
available from any other drug screening procedure.
Psychemedics' test detects drugs of abuse for the
previous 90 days, while urinalysis will detect use
for only the previous 2-3 days for most drugs.
Psychemedics' significantly longer testing window
results in superior detection rates over urinalysis.
In addition, the collection of a hair sample is
easier and far less embarrassing than a urine sample.
All initial positives are confirmed using gas
chromatography/mass spectrometry (GC/MS). Test
results have been consistently upheld in court. In fact, some
court systems currently rely on Psychemedics'
technology in their probation programs.
The History of Psychemedics' Technology
Psychemedics' patented technology was pioneered in
1977 by Dr. Werner Baumgartner and Annette
Baumgartner. Over ten years of research funded by the
National Institute of Justice, the Veteran's
Administration, the United States Navy and the
American Society for Industrial Security on thousands
of test subjects have proven that drugs deposited in
hair can be measured by radioimmunoassay and
ultrasensitive gas chromatograph/mass spectrometry
procedures. The effectiveness of hair analysis for
drugs of abuse has been documented in more than 500
scientific publications worldwide.
In 1987 Psychemedics became the world's first
laboratory to offer a cost effective method for
testing using hair rather than body fluids for the
detection of drugs of abuse.
Psychemedics' Patents
Psychemedics is the first company to have been awarded both U.S. and
foreign patents for the detection of
drugs in hair. The first U.S. and European patent
covers the universal drug extraction procedure for
the detection of drugs in hair specimens.
The second U.S. patent covers the removal of
substances which interfere with the immunochemical
screening assay for marijuana. The marijuana
screening assay is the most challenging scientific
problem of hair analysis.
These patents enable Psychemedics to conduct
testing far more effectively than other laboratories
claiming the ability to detect drugs through hair
analysis. More recently, Psychemedics received both European and Japanese patents for its method of hair analysis. |
