Hair analysis has become recognized as an effective means for identifying alcohol and drug consumption. Hair records a comprehensive timeline of alcohol and drug intake by capturing biomarkers within the strands of hair as they grow. When hair is clipped near the scalp, it can offer a retrospective window of up to roughly 90 days for alcohol and drugs. Hair is straightforward to obtain, relatively tamper-resistant, and convenient for transport.
A hair sample of 1.5 inches consisting of approximately 200 strands (comparable to the girth of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal quantity for initial tests and verification. For EtG, supplementary tests, or analyses exceeding 10 panels, a sample of 150mg is advisable. It is suggested that the sample be weighed using a jeweler’s scale. If scalp hair is not accessible, an equivalent quantity of body hair can be used. When addressing head hair, it specifically refers to scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary workflow of integrating a sample into a laboratory’s records. This step includes ensuring that the sample is correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional entries absent from an electronic custody system.
Screening performs a preliminary assessment for substance abuse. While Screening is a cost-effective method to exclude drug use for most samples, a confirmed positive result is necessary for legal proceedings. Any samples flagged as potentially positive during Screening require a further confirmation test.
Should a sample be potentially positive at the Screening phase, additional hair is utilized from the initial sample to prepare for Extraction. This step isolates drugs from hair at much lower concentrations compared to other methods such as urine or saliva, which is why hair drug screening is considered the most challenging procedure.
Confirmation of any positive Screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that indicate a presumptive positive are cleansed before confirmation as needed. The complete lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation standards.
