Hair evaluation is increasingly recognized as an effective method for detecting the consumption of drugs and alcohol. It offers an extended record of substance use by capturing biomarkers within the fibers of the developing hair shaft. When gathered near the scalp, it can provide an approximately 3-month window for identifying alcohol and drug usage. Hair is straightforward to collect, relatively resistant to tampering, and simple to transport.
A 1.5-inch section of roughly 200 hairs (comparable to a #2 pencil in thickness) near the scalp supplies approximately 100mg of hair, which is ideal for both screening and verification. For EtG, supplementary analyses, and/or assessments beyond 10 panels, 150mg of hair is suggested. Using a jeweler’s scale for weighing the sample is advisable. If scalp hair is not an option, equivalent body hair may be used. When discussing head hair, it specifically refers to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four key stages in the lab analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the preliminary processing of a specimen into a lab’s system occurs. This process includes ensuring the sample was correctly sealed and shipped, allocating a unique LAN (Laboratory Accessioning Number), and completing any additional information entry that an electronic chain of custody system may lack.
Screening involves an initial brief evaluation for substance misuse. Though Screening is a cost-efficient method for excluding drug use in most cases, a positive screen requires confirmation for legal acceptance. Any specimens presumed positive in Screening necessitate further confirmation.
Should a sample appear positive in Screening, additional hair is taken from the original specimen for Extraction. This phase extracts drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug analysis the most challenging approach to implement.
Confirmation of any positive screening outcome is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as needed. The entire laboratory procedure, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
