Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. Hair retains a long-term record of substance use by encapsulating biomarkers within the hair's growing strands. When collected near the scalp, a sample may provide up to a 90-day window for detecting drugs and alcohol. Hair is easy to collect, somewhat resistant to tampering, and simple to transport.
An ideal sample for testing and confirmation is a 1.5-inch section of around 200 hair strands (approximately the diameter of a #2 pencil) near the scalp, yielding 100mg of hair. For EtG, additional tests, or panels exceeding ten, a 150mg specimen is preferable. We suggest weighing the sample using a jeweler’s scale. Should scalp hair be unavailable, a comparable amount of body hair can be used. By head hair, we mean scalp hair exclusively. Body hair encompasses all other hair forms (facial, axillary, and so on).
Process Overview
The laboratory processing of a drug test result involves four core steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial processing where the lab system verifies the sample's sealing and proper shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not handled by an electronic chain of custody system.
Screening provides a preliminary assessment for substance misuse. While Screening is an economical method for excluding drug use in most samples, positive results require confirmation for legal acceptability. Any samples presumed positive in Screening need secondary verification.
If presumed positive in Screening, additional hair is extracted from the original sample for the Extraction process. This step isolates drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing one of the most complex methodologies.
Positive screenings undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are washed as needed before confirmation. The full lab process from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards accreditation.
