Hair analysis is now recognized as a robust method for identifying substance and alcohol use. Hair preserves a comprehensive history of these substances by capturing biomarkers within its strands. Collected near the scalp, hair can offer a detection window extending up to three months for these substances. Collection is straightforward, its alteration is challenging, and shipping is uncomplicated.
A 1.5-inch sample containing roughly 200 hairs (around the thickness of a #2 pencil) nearest the scalp provides 100mg, which is optimal for screening and confirmation. For EtG assessments, additional tests, or those exceeding 10 panels, 150mg of hair is advised. We suggest weighing the hair on a jeweler’s scale. If scalp hair is inaccessible, an equivalent amount of body hair is acceptable. "Head hair" denotes only scalp hair. "Body hair" includes facial, axillary, and other hair types.
Process Overview
The laboratory process for a drug test result involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the lab’s framework, confirming correct sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and inputting any additional data absent from an electronic chain of custody system.
Screening conducts a preliminary rapid analysis for drug presence. While cost-efficient in excluding drug use for most samples, a positive screen needs confirmation for legal admissibility. Samples showing a presumptive positive in Screening require secondary confirmation.
Should a sample test presumptively positive during Screening, additional hair is taken from the initial batch for Extraction. This phase extracts drugs at lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug analysis one of the most challenging techniques to execute.
Confirmation of any positive result from Screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive are cleaned before confirmation as necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
