Hair analysis has become a significant resource for identifying drug and alcohol consumption. By encapsulating biomarkers within the fibers, hair offers an extensive timeline for detecting alcohol and other substances. Captured near the scalp, hair demonstrates a detection window stretching up to a 3-month period for alcohol and drugs. Collection is straightforward, modifying it is challenging, and transportation is simple.
A 1.5-inch section containing approximately 200 hair strands (roughly equivalent to a #2 pencil) from the scalp section ensures a 100mg hair collection, the preferred sample for screenings and verifications. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is preferred. Using a jeweler’s scale to weigh samples is advised. If scalp hair is unavailable, a similar volume of body hair can be utilized. References to head hair imply only scalp hair, while body hair encompasses all other forms (facial, axillary, etc.).
Process Overview
The laboratory procedures for drug test analysis encompass four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with incorporating a sample into the laboratory’s system. This step confirms the sample's proper sealing and shipping, generates a random LAN (Laboratory Accessioning Number), and completes any missing data not inputted via an electronic chain of custody system.
Screening performs a preliminary check for drugs. Although cost-effective in excluding drug presence in most samples, a positive screen demands confirmation for legal acceptability. Any samples showing presumptively positive in Screening need further verification.
If Screening yields a presumptive positive, additional hair is retrieved from the initial sample for Extraction. During this phase, drugs are extracted at significantly reduced concentrations compared to other methods (e.g., urine or oral fluids), which is why hair drug screening stands as the most complex methodology to execute.
Any positive result from screening undergoes confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptive positive samples are washed when necessary. The entire lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
