Hair analysis has been recognized as a valuable method for identifying drug and alcohol consumption. Hair provides an extended timeline for alcohol and other drugs by locking biomarkers within the fibers of the developing hair strand. When procured near the scalp, hair can offer up to roughly a 3-month period for detecting alcohol and other drugs. Hair collection is straightforward, challenging to tamper with, and convenient for transportation.
A sample measuring 1.5 inches consisting of approximately 200 hair strands (roughly the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, supplementary tests, and/or evaluations exceeding 10 panels, 150mg of the sample is suggested. It is advisable to weigh the specimen using a jeweler’s scale. If head hair is unavailable, an equivalent quantity of body hair may be gathered. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The four fundamental steps in the laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of integrating a sample into a lab’s system. This phase includes confirming that the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not covered by an electronic chain of custody system.
Screening offers an initial rapid assessment for drugs of misuse. Although Screening is a cost-efficient method to exclude drug use for the bulk of samples, a positive screen must be validated to be credible in legal settings. Any samples that appear positive in Screening necessitate further confirmation.
Should a sample exhibit positive results in the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. In this phase, drug extraction from hair occurs at a notably lower concentration than in other procedures (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity undergo washing before confirmation as required. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.
