Hair analysis is now recognized as an effective method for identifying drug and alcohol use. Hair captures the history of alcohol and other drugs by embedding biomarkers within the strands as they grow. When taken near the scalp, hair samples can deliver an estimated three-month detection span for substances like alcohol and drugs. Hair is not only easy to gather, but also relatively tamper-resistant and straightforward to transport.
A snippet measuring 1.5 inches, consisting of approximately 200 hair strands (about the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For tests that include EtG, additional panels, or tests exceeding 10 panels, a 150mg sample is suggested. We advise weighing the sample using a jeweler's scale. In cases where scalp hair isn’t accessible, a similar amount of body hair may be used. When we refer to head hair, we mean only scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test outcome in the laboratory encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a lab's system. This step verifies the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any further data entry absent from an electronic chain of custody system.
Screening performs an initial drug abuse check. Though it's a cost-efficient method to exclude drug use in most samples, a positive result in Screening must be confirmed for legal admissibility. Any sample with a presumptive positive in Screening requires secondary verification.
Should a sample yield a presumptive positive during Screening, additional hair is retrieved from the initial sample and prepped for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening exceedingly challenging.
Confirmation of any positive screening result is achieved using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The entire lab process is scrutinized, from Accessioning to Confirmation, under both CAP (College of American Pathologists) Hair classification and the compliance with ISO / IEC 17025 standards.
