A simple scientific fact: drugs, which are ingested, circulate in a person's bloodstream which nourishes the developing hair follicle.

Trace amounts of the drugs become entrapped in the core of the hair shaft in amounts roughly proportional to those ingested. These traces remain in the hair as it grows out from the head at a rate of approximately one-half inch per month.

A person's drug usage history can be obtained from the hair of any individual. Drug use can be detected from months, even years past, depending on the length of the sample.

Standard drug tests currently provide a 90 day history of drug use.

Radioimmunoassay of Hair drug test is a proven drug testing procedure which not only detects if drugs of abuse have been used, but also provides information in the quantity of drugs consumed by an individual and the historic pattern of drug use. This type of information is not available from any other drug-screening procedure.

The Radioimmunoassay hair testing process was pioneered in 1977 by Annette Baumgartner and Dr. Werner Baumgartner.

Over ten years of research funded by the United States Navy, the Veteran's Administration, the American Society for Industrial Security and the National Institute of Justice on thousands of subjects has proven that drugs deposited in the hair can be measured by radioimmunoassay and ultrasensitive gas chromatography/mass spectrometry procedures.

There have been over 75 scientific publications worldwide, including reports from the Federal Bureau of Investigation and the U.S. Navy.

5 to 10 times as many drug abusers are accurately identified with the Radioimmunoassay hair test.
