Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. Hair integrates long-term evidence of alcohol and illicit substances by capturing biomarkers within the fibers of the developing hair shaft. When obtained near the scalp, hair offers a detection span extending to nearly three months for alcohol and drugs. Collecting hair is uncomplicated, relatively tough to tamper with, and straightforward to transport.
A 1.5-inch portion of about 200 hair fibers (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, an optimal sample for initial screening and confirmation. For EtG cases, supplementary tests, and/or panels exceeding ten, a 150mg specimen is advisable. It's best to weigh the sample using a jeweler’s scale. Should scalp hair be inaccessible, a similar quantity of body hair is permissible. References to head hair denote solely scalp hair. Body hair includes all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test outcome comprises four core stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the primary processing of a specimen into a lab's system. This process ensures the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and finalizes any missing data entry absent in an electronic chain of custody mechanism.
Screening executes an initial rapid assessment for substance abuse. Though Screening is cost-efficient for ruling out drug consumption in most samples, a positive screening mandates confirmation for legal admissibility. Any samples deemed presumptively positive in Screening require further confirmation.
For samples deemed presumptively positive in the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In this phase, substances are sourced from hair at a notably lower concentration than alternative methods (e.g., urine or oral fluid), underscoring why hair drug analysis is the most challenging practice to execute.
Verification of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to verification as needed. The full laboratory process, spanning from Accessioning through Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair classification and conforms to ISO / IEC 17025 accreditation standards.
