Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. The growing fiber of hair retains biomarkers, which offer an extended overview of substances like alcohol and drugs. When collected from near the scalp, hair samples can demonstrate substance use information for a timeframe of up to three months. It's straightforward to collect, resistant to tampering, and convenient to transport.
A 1.5-inch segment comprising roughly 200 hair strands (approximately the width of a #2 pencil) from nearest the scalp provides 100mg, which is the optimal sample size for screening and confirmation processes. For EtG, supplemental, and/or tests beyond 10 panels, it's advised to obtain 150mg. Utilizing a jeweler's scale for the specimen's measurement is advisable. In the absence of head hair, a comparable quantity of body hair may be gathered. In terms of head hair, only scalp hair is considered, whereas body hair encompasses all other hair categories (like facial and axillary hair).
Process Overview
Four primary phases exist in the laboratory analysis of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial intake process of a sample into the laboratory system. This phase includes confirming the sample's secure sealing and shipment, the assignment of a random LAN (Laboratory Accessioning Number), and completing any additional entries excluded by a digital chain of custody system.
Screening offers an initial cursory analysis for substance abuse. While cost-effective for negating substance use across most samples, a positive screen necessitates confirmation for legal admissibility. All samples that indicate positive results in Screening require secondary confirmation.
When a sample returns a presumptive positive at the Screening point, additional hair is collected from the initial sample for Extraction. Here, drugs are drawn out from hair at considerably lower concentrations compared to other methods (such as oral fluid or urine), underlining the complexity of hair drug screening as a methodology.
GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed to affirm any positive screening findings. Presumptive positive samples undergo washing prior to confirmation when needed. The comprehensive laboratory evaluation, from Accessioning to Confirmation, is carried out under the oversight of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
