Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers in the fibers of the developing hair strand. When taken near the scalp, hair can offer up to roughly a 90-day detection timeframe for alcohol and other substances. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.
A 1.5-inch segment of approximately 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp yields 100mg of hair, which is the optimal sample size for analysis and verification. For EtG, supplementary tests, and/or assessments exceeding 10 panels, it's advised to use 150mg of the sample. We suggest evaluating the sample’s weight using a jeweler's scale. If scalp hair is unavailable, an equivalent quantity of body hair can be obtained. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types (e.g., facial, axillary, etc.).
Process Overview
The four essential steps integral to laboratory analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into a laboratory’s framework. This step involves ensuring the sample was securely sealed and transported, generating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening constitutes a preliminary rapid assessment for abuse substances. Although Screening is an affordable approach to exclude drug consumption in most samples, a positive screening necessitates confirmation to be valid in court. Samples that are tentatively positive in Screening require a subsequent confirmation.
Upon a tentative positive result in the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are retrieved from hair at significantly reduced concentrations compared to other techniques (e.g., urine or oral fluid), which is why hair drug testing is among the most challenging methodologies.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All tentatively positive samples are cleansed before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
