Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. It provides a prolonged timeline of substance use by embedding biomarkers within the hair strand's fibers. When hair is harvested near the scalp, it offers roughly a three-month period for detecting substances. Hair collection is straightforward, fairly resistant to tampering, and convenient to transport.
A hair sample of 1.5 inches, containing approximately 200 strands (akin to the girth of a #2 pencil), secured closest to the scalp, yields 100mg – the preferred quantity for both screening and verification. For EtG additions or tests exceeding ten panels, 150mg of the hair is suggested. Measurement of the sample using a jeweler’s scale is advisable. If scalp hair cannot be obtained, an equivalent quantity of body hair may be used. The term head hair specifically refers to scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory protocol for processing drug tests includes four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the primary handling of a specimen within the lab's framework. This step ensures the sample was properly sealed and delivered, assigns an arbitrary LAN (Laboratory Accessioning Number), and fulfills any additional documentation not covered by a digital chain of custody system.
Screening performs an initial, swift assessment for misuse of substances. Although Screening is a budget-friendly strategy to eliminate drug presence in most samples, a positive outcome necessitates validation for legal admissibility. Any specimens showing presumptive positive results during Screening require secondary verification.
If the Screening phase indicates a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. Here, the method extracts drugs from hair at significantly lower concentrations than other procedures (e.g., urine or saliva), underscoring the complexity of performing hair drug testing.
Validation of any positive screening is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation as deemed necessary. The complete lab process from Accessioning through to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and the ISO/IEC 17025 accreditation protocols.
