Hair screening has emerged as an effective technique for identifying drug and alcohol consumption. Hair offers an extended record of substances by embedding biomarkers within the strands of growing hair. When collected adjacent to the scalp, hair provides up to a 3-month timeframe for detecting drug and alcohol use. It is easy to collect hair samples, they're harder to tamper with, and they ship conveniently.
A 1.5-inch segment consisting of about 200 hair strands (approximately the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, optimal for analysis and verification. For EtG, additional screenings, and/or tests beyond 10 panels, a 150mg specimen is advisable. Using a jeweler’s scale is recommended for weighing. If scalp hair is unavailable, an equivalent portion of body hair is acceptable. With head hair, we're specifically referring to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The key phases in laboratory processing of a drug test outcome encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning represents the initial integration of a sample into the lab’s system, which includes verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.
Screening involves an initial assessment for substance abuse. While Screening is a cost-efficient method for most samples to rule out drug presence, a positive screening necessitates confirmation to be court-admissible. Presumptively positive samples in Screening require a secondary verification.
For samples showing presumptive positive results in the Screening phase, additional hair is extracted from the initial sample for the Extraction stage. At this point, substances are pulled from hair at lower concentrations compared to other methodologies (e.g., urine or oral fluid), illustrating why hair drug screening is a challenging procedure.
Confirmation of any positive screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo necessary washing. The complete lab process from Accessioning through Confirmation is assessed under CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
