Recognized as a potent means for detecting drug and alcohol consumption, hair tests reveal a comprehensive record by embedding biomarkers within the hair’s growing strands. Proximity to the scalp hair sample yields a retrospective drug detection period extending up to 90 days for substances. Hair collection is straightforward, relatively resistant to tampering, and conveniently transportable.
Gathering a 1.5-inch segment comprising roughly 200 hairs (comparable to a #2 pencil) close to the scalp provides 100mg, deemed ideal for screening and confirmation. For EtG assessments, additional tests of over ten panels or requirements, a greater sample of 150mg is advisable. Using a jeweler's scale for sample weighing is recommended. Should scalp hair be unavailable, equivalent body hair may substitute. When mentioning head hair, it pertains solely to scalp follicles whereas body hair references other types such as facial and axillary hair.
Process Overview
The core stages of the lab-based drug test evaluation are: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses initial sample preparation within a lab system, incorporating checks on sealing and transportation, assigning a Laboratory Accessioning Number (LAN), and completing further data entry when absent from an e-chain of custody system.
Screening presents a rapid initial drug assessment. While cost-effective for broadly determining drug non-use, positives require confirmation for legal adjudication. Any presumed positive results from Screening necessitate subsequent confirmation.
For presumptive positives from Screening, additional hair is extracted from the preliminary sample and readied for Extraction. In this phase, drug extraction from hair occurs at notably lower concentrations versus methods like urine or oral fluid, underscoring the complexity of hair drug screenings.
Confirmation of positive screens is completed using GC/MS, GC/MS/MS, or LC/MS/MS. If necessary, all samples with presumed positives undergo a wash before Confirmation. The meticulous sequence from Accessioning to Confirmation undergoes scrutiny under both the CAP Hair designation and accreditation per ISO/IEC 17025 standards.
