Hair analysis is now recognized as an effective method for identifying drug and alcohol intake. The structure of hair captures biomarkers over time, providing an extended history of substance exposure when gathered near the scalp, offering a detection window of up to three months for drug and alcohol usage. The collection process is straightforward, the potential for tampering is low, and the samples are easy to transport.
A 1.5-inch lock of approximately 200 hair strands (similar in thickness to a #2 pencil) closest to the scalp yields 100mg, the optimal quantity for screening and verification. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg is suggested. We advise measuring the sample with a jeweler’s scale. If scalp hair isn't available, a comparable amount of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair includes all other hair classifications (facial, axillary, etc.).
Process Overview
There are four key stages in the laboratory processing of drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary treatment of a sample into a lab system. This phase verifies the sample was sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input necessary beyond what the electronic chain of custody system supplies.
Screening incorporates an initial expedient assessment for drugs of abuse. Despite its cost-effectiveness for ruling out drug presence in most samples, confirming positive screens is essential for legal acceptability. Any samples presumed positive during Screening need secondary confirmation.
Should a sample show presumptive positivity at Screening, extra hair is extracted from the initial sample for the Extraction phase. Here, the process involves removing drugs from hair at significantly lower concentrations compared to other methods (e.g. urine or oral fluid), highlighting why hair drug analysis is among the most challenging techniques.
Confirmation for any positive screen outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing before confirmation if necessary. The entire lab procedure, from Accessioning to Confirmation, is assessed according to the CAP (College of American Pathologists) Hair classification and accredited to ISO / IEC 17025 standards.
