Hair assessments now represent an effective approach to identify substance and alcohol consumption. Hair offers an extended history of alcohol and drug use by encapsulating biomarkers within the fibers of the progressing hair strand. Acquired close to the scalp, hair can yield up to a 3-month timeframe for detecting alcohol and drugs. Collection is straightforward, tampering is challenging, and transport is uncomplicated.
A specimen of 1.5 inches composed of around 200 hair strands near the scalp provides 100mg, the perfect quantity for evaluation and verification. For EtG, enhanced panels, or tests exceeding 10 categories, 150mg of the hair sample is advised. Utilization of a jeweler’s scale for weighing is suggested. If head hair isn’t available, an equivalent batch of body hair is acceptable. References to head hair indicate scalp hair exclusively. Body hair includes all other varieties (facial, axillary, etc.).
Process Overview
The core stages in the laboratory processing of a substance test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the initial incorporation of a sample into the lab’s system, confirming proper sealing and dispatch, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent in an electronic custody chain.
Screening gives a preliminary check for substance abuse. Although cost-efficient for ruling out usage in most samples, a positive screen must be verified for court acceptance. All samples indicating probable positive results in Screening require secondary confirmation.
If Screening shows a presumptively positive result, further hair is extracted from the original sample for Extraction. During Extraction, substances are drawn from hair at a lower concentration than alternative methods (ex. urine or oral fluid), thus making hair drug testing the most complex method to execute.
Confirming any positive screen is done through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
