Occupational Drug Screening | Hair Testing

Hair follicles provide a record of drug use over long periods of time – up to 90 days. Hair testing is very challenging – nearly impossible – to cheat, even if an employee briefly stops using. Many drugs of abuse can be successfully detected using hair testing, including benzodiazepines, cocaine, marijuana (THC, cannabinoids), amphetamines, and more. Agilent provides state-of-the-art GC/MS/MS or LC/MS/MS methods to measure a variety of drugs of abuse in hair.
