What is hair testing?
Since hair growth is fed by the bloodstream, the ingestion of drugs of abuse is revealed by analyzing a small sample of hair. Our testing method measures the drug molecules embedded inside the hairshaft, eliminating external contamination as a source of a positive test result. Hair testing results cannot be altered with shampoos or other external chemicals.
Hair testing analyzes for drugs within the hair shaft, rather than body fluids like urine or saliva, to determine whether drugs of abuse are present. Compared to analysis of body fluids, hair testing is highly resistant to evasion by adulterating or substituting samples, or by simply abstaining from drug use for a few days. Psychemedics’ proprietary method for detecting drugs in hair uses radioimmunoassay and state-of-the-art GC/MS/MS or LC/MS/MS confirmation to measure the drug molecules and metabolites permanently entrapped in hair which were incorporated following ingestion. This technology offers significantly greater detection ability than other methods of analyzing hair or body fluids.
