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. 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. There are companies who have tried to emulate our proprietary process of hair analysis. It is important to remember that all hair testing is not of the same quality.
