Hair analysis is increasingly recognized as a robust method for identifying substance and alcohol consumption. Hair acts as a repository for long-term alcohol and drug history by embedding biomarkers in the hair shaft as it grows. Collected near the scalp, it offers a detection period of up to about 3 months for substances including alcohol. This method is simple to collect, relatively tamper-proof, and easy to ship.
Gathering a 1.5-inch sample of around 200 hair strands (approximately a #2 pencil's thickness) nearest the scalp yields 100mg of hair, which is optimal for testing and confirmation. For EtG, additional tests, and those exceeding 10 panels, 150mg is preferred. We suggest using a jeweler's scale for weighing. Absent scalp hair, collect an equivalent volume of body hair. "Head hair" refers specifically to scalp hair, whereas "body hair" encompasses all other types (facial, axillary, etc.).
Overview of the Procedure
The drug testing process in the lab includes four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the sample's initial integration into the lab's procedures. This phase ensures the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any lacking data entry not covered by an electronic chain of custody system.
During Screening, samples undergo a preliminary rapid assessment for drug substances. This cost-efficient stage helps to eliminate most negative samples. However, for legal acceptability, any positives require further confirmation as preliminary positive results must be verified.
With a presumptive positive found in Screening, more hair is extracted from the preliminary sample and processed for Extraction. This phase extracts drugs from the hair at far lower concentrations than other methods (e.g., urine or saliva), making hair drug screening one of the most challenging techniques.
GC/MS, GC/MS/MS, or LC/MS/MS is employed to confirm any positive screens. All samples flagged as presumptive positives are cleansed before confirmation as needed. The comprehensive process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 certification.
