Hair analysis is now recognized as a robust method for detecting drug and alcohol consumption. Hair retains a comprehensive record of alcohol and other drugs by embedding biomarkers within the fibers of the growing hair strand. When gathered near the scalp, hair can offer a detection timeframe of up to around 3 months for alcohol and other drugs. It is straightforward to collect hair, relatively difficult to tamper with, and convenient to ship.
A 1.5-inch sample consisting of about 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the optimal sample size for screening and confirmation. For EtG, additional tests, and/or those above 10 panels, a 150mg specimen is advisable. It's advisable to weigh the specimen using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be gathered. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Summary
There are four primary phases in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary processing of a sample into a laboratory’s system. This phase entails verifying the sample was securely sealed and properly shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry not provided via an electronic chain of custody system.
Screening involves an initial rapid assessment for drugs of abuse. Screening presents a cost-efficient means to rule out drug use in the majority of samples, though a positive screen necessitates confirmation to be acceptable in court. Any samples that are preliminarily positive in Screening require a subsequent confirmation.
If a sample is preliminarily positive at the Screening phase, more hair is extracted from the original specimen for the Extraction process. During this phase, drugs are extracted from hair at a considerably lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to conduct.
Confirmation for any positive screening result is executed using GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as required. The entire laboratory procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
