Hair analysis is now regarded as a robust approach for identifying narcotics and alcohol consumption. Hair offers an extended timeline of substance use by embedding biomarkers within the structure of the growing hair shafts. When harvested near the scalp, hair can reveal up to about a three-month timeframe for the detection of alcohol and drugs. Hair is straightforward to collect, somewhat challenging to tamper with, and convenient to transport.
A 1.5-inch portion consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal quantity for initial screening and confirmation tests. For EtG, additional tests, and/or analyses exceeding 10 panels, 150mg of hair is advised. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair cannot be obtained, an equivalent quantity of body hair may be used. "Scalp hair" specifically denotes head hair. "Body hair" encompasses all other hair types (facial, underarm, etc.).
Process Overview
The key stages in the laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning concerns the preliminary handling of a sample into a lab’s database. This stage verifies the proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any additional information entry absent from an electronic custody chain system.
Screening provides an initial rapid assessment for substances of abuse. Although Screening is economical for excluding drug usage in most samples, a positive result requires verification for legal admissibility. Any samples preliminarily positive in Screening necessitate further confirmation.
Should a sample preliminarily test positive in the Screening phase, additional hair is drawn from the primary specimen for Extraction. Here, substances are removed from hair at significantly lower concentrations than alternative methods (such as urine or oral fluid), which contributes to hair drug testing being the most complex method to execute.
Validation of any positive screen outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete lab process, from Accessioning through to Confirmation, undergoes assessment under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
