Hair analysis has emerged as an effective approach for detecting substance use. By embedding biomarkers in the hair shaft, hair offers an extensive timeline of alcohol and substance presence. When clipped near the scalp, hair can reveal drug and alcohol activity up to a roughly 3-month timeframe. Hair is straightforward to gather, less prone to tampering, and convenient to send.
A 1.5-inch portion of around 200 hairs (comparable to a #2 pencil's thickness) nearest the scalp provides a 100mg sample, optimal for both screening and validation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advisable. We suggest using a jeweler’s scale for exact weighing. If scalp hair can't be used, an equivalent amount of body hair is acceptable. “Head hair” refers explicitly to scalp hair. “Body hair” encompasses all other hair types (facial, axillary, etc.).
Process Overview
The drug testing procedure in a lab comprises four main phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, samples are initially processed into the lab’s framework. This step ensures proper sealing and shipping of the sample, allocates a random LAN (Laboratory Accessioning Number), and completes any manual data entry absent in an electronic chain of custody.
Screening performs an initial rapid detection for substance abuse. Although a cost-effective method for dismissing drug use in most samples, a positive result from Screening requires subsequent validation before legal presentation. Samples with presumptive positives in Screening necessitate further verification.
When Screening indicates a presumptive positive, additional hair is extracted from the original sample for Extraction. Here, substances are drawn from hair at far lower concentrations than in alternative methods (e.g., urine or saliva), making hair drug analysis the most challenging technique.
Positive results in Screening are validated through GC/MS, GC/MS/MS, or LC/MS/MS processes. Prior to validation, all presumptive positive samples are cleansed as needed. The complete lab workflow from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 certification.
