Hair analysis has increasingly been recognized as a robust method for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and other substances by embedding biomarkers within the strands as they grow. When collected near the scalp, hair can offer a detection period extending up to around three months for alcohol and other drugs. Gathering hair samples is straightforward, relatively tamper-resistant, and easy to transport.
A hair sample measuring 1.5 inches, consisting of roughly 200 strands (equivalent to the thickness of a #2 pencil) nearest to the scalp, provides 100mg of hair, the preferred quantity for both screening and validation. For EtG, additional tests, or analyses above 10 panels, a specimen amounting to 150mg is advisable. Using a jeweler’s scale for weighing the specimen is suggested. If scalp hair is not available, an equivalent volume of body hair can be collected. By head hair, we specifically mean scalp hair, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial entry of a sample into the laboratory system. This involves confirming that the sample is appropriately sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not captured by an electronic chain of custody system.
Screening consists of a preliminary assessment for drug abuse. Although Screening offers a cost-effective means to rule out drug use for most specimens, a positive screen necessitates confirmation for legal admissibility. Samples testing positive in Screening mandate further verification.
When a sample tests positive in the Screening phase, additional hair is extracted from the initial sample and processed for Extraction. In this phase, drugs are extracted from hair in much lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug screening is the most challenging technique to conduct.
Confirmation of a positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive specimens are cleaned as required. The complete lab process, from Accessioning to Confirmation, is thoroughly reviewed under both the CAP (College of American Pathologists) Hair classification and ISO/IEC 17025 standards accreditation.
