Hair analysis is increasingly regarded as a formidable mechanism for unveiling drug and alcohol consumption. It chronicles a prolonged timeline of substance use by capturing biomarkers within the constructs of extending hair strands. When sourced adjacent to the scalp, hair reveals insights on alcohol and drug usage over nearly a 90-day trajectory. Collection is straightforward, tough to modify, and conveniently transportable.
A 1.5-inch segment comprising approximately 200 hair strands (equivalent to a #2 pencil’s girth) near the scalp equates to 100mg of hair—an optimal quantity for screening and verification. For EtG, additional assessments, and/or analyses exceeding 10 panels, 150mg of the specimen is advocated. It is advisable to measure the sample on a jeweler’s balance. If hair from the scalp is scarce, an equal portion of body hair might be utilized. 'Head hair' pertains exclusively to scalp hair, whilst 'body hair' encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory procedure for decoding a drug test outcome encompasses four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the introductory processing of a specimen into a lab’s system. This procedure ensures that the sample was appropriately sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry absent in an electronic chain of custody system.
Screening encompasses a preliminary cursory examination for substance abuses. Though Screening economically eliminates drug usage in most cases, positive readings necessitate confirmation to be court-ready. Any prospectively positive samples from Screening demand an auxiliary validation.
For samples flagged as potentially positive during Screening, additional hair is extracted from the initial specimen for Extraction. At this juncture, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), establishing hair testing as the most challenging process to execute.
Confirmation of any positive outcomes from screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All tentatively positive samples undergo washing pre-confirmation when required. Each stage from Accessioning to Confirmation is evaluated in accordance with both CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
