Hair analysis is increasingly recognized as a potent method for identifying drug and alcohol consumption. Hair offers a prolonged record of substance use by embedding chemical indicators within the hair's growing fiber. When sampled close to the scalp, hair can reflect a detection period of up to approximately three months for alcohol and other substances. Hair is straightforward to gather, somewhat resistant to tampering, and convenient to transport.
A 1.5-inch segment of around 200 hair strands (akin to the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is the preferred quantity for both screening and confirmation. For EtG, additional tests, or screenings exceeding 10 panels, 150mg is advised. We suggest measuring the sample using a jeweler’s scale. If scalp hair is absent, a corresponding quantity of body hair may be used. When mentioning head hair, we refer exclusively to scalp hair. Body hair encompasses other varieties (facial, underarm, etc.).
Process Overview
The primary stages in processing a laboratory drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a specimen within a laboratory’s system. This encompasses ensuring the specimen was appropriately sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any essential data entry not covered by an electronic custody system.
Screening involves a preliminary assessment for drug traces. Though Screening offers a cost-efficient approach to negate drug use in most samples, a positive result requires confirmation for legal acceptance. Any specimens that appear positive in Screening necessitate a subsequent validation.
If a specimen is tentatively positive during the Screening phase, more hair is extracted from the original sample and readied for Extraction. Here, drugs are derived from hair at significantly reduced concentrations than other methods (like urine or saliva), making hair drug screening a highly intricate process.
Confirmation of any positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed prior to Confirmation as applicable. The full lab procedure from Accessioning to Confirmation is overseen by both the CAP (College of American Pathologists) Hair criteria and the standardization to ISO / IEC 17025.
