Hair Testing Pioneer and Leader
Psychemedics pioneered the use of hair testing over 25 years ago, after years of research proved that drugs deposited in the hair can be accurately measured. Hair analysis is a test in which a sample of a person’s hair is sent to a laboratory to detect illicit drug use.
The technology capitalizes on the way the body metabolizes ingested drugs as they flow through the blood stream and deposit in the cortex of the hair. Hair is stable and the deposits are permanently embedded in the hair, so hair acts like a tape recorder — “recording” drug deposits in proportion to the use over time as drugs are deposited in proportion to use.
The two tests used by Psychemedics to analyze hair samples for the presence of drugs of abuse are an FDA-cleared immunoassay test followed by confirmation by mass spectrometry (MS/MS in most instances).
Hair Testing is Based on a Simple Scientific Principle
- Ingested Drugs Are Entrapped in Hair
- Drugs Accumulate in Proportion to Use
- Permanent Historical Record of Substance Abuse
