Hair analysis is now recognized as an effective method for identifying alcohol and drug usage. The structure of hair captures substances from the bloodstream, providing an extended record of drug and alcohol presence. Samples collected near the scalp can reflect drug consumption over roughly a three-month period. The procedure for collecting hair is straightforward, the chances of tampering are low, and shipping is uncomplicated.
By obtaining a 1.5-inch sample of approximately 200 hair strands near the scalp, one can acquire 100mg of hair—considered optimal for testing purposes. For EtG assessments, additional tests, or those beyond 10 panels, 150mg of the sample is suggested. Utilizing a jeweler's scale can ensure accurate measurement. Should scalp hair be missing, a comparable quantity of body hair can be used. 'Head hair' specifically pertains to scalp hair, while 'body hair' encompasses all other types (such as facial or axillary hair).
Process Overview
The drug testing protocol at laboratories involves four essential stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially recorded into the lab system, ensuring it was sealed and delivered correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any requisite data input absent in the electronic chain of custody.
Screening comprises a swift preliminary assessment for substance abuse. Although Screening economically rules out drug presence in most instances, a positive screen mandates confirmation for legal acceptance. Any tentatively positive results in Screening necessitate further verification.
Should a Screening result be tentatively positive, additional hair is retrieved from the existing sample for Extraction. At this stage, the substances are extracted from hair at concentrations significantly lower than in other testing mediums (such as urine or oral fluids), which is why hair testing is notably challenging.
For validating positive results from Screening, methodologies such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. Before Confirmation, all samples testing presumptive positive undergo a cleansing procedure if necessary. The complete process, from Accessioning to Confirmation, adheres to both CAP's (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
