Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair retains a long-term record of such substances by capturing biomarkers inside the strands as they develop. When the hair is obtained near the scalp, it can offer up to a 90-day detection period for alcohol and other drugs. Collecting hair is straightforward, not easily tampered with, and convenient for shipping.
A 1.5-inch segment of roughly 200 hairs (approximately the diameter of a #2 pencil) from the scalp supplies 100mg, which is the optimal amount for analysis. For tests like EtG, add-ons, or those exceeding 10 panels, a specimen of 150mg is advisable. We suggest using a jeweler’s scale for accuracy. If scalp hair isn't an option, an equivalent quantity of body hair can be used. References to head hair mean scalp hair solely. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug tests encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of a sample within a laboratory’s framework. This step ensures the sample was sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data input not included by an electronic chain of custody system.
Screening comprises an initial rapid assessment for potential drug abuse. Though Screening is a budget-friendly approach to exclude drug use for most samples, a positive result demands confirmation for legal admissibility. Samples that are presumptively positive in Screening must undergo further confirmation.
If a sample suggests positivity during Screening, additional hair is extracted from the original specimen and prepped for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than in other tests (e.g., urine or oral fluid), making hair drug screening the most complex method to execute.
Confirmation of any screening-positive outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed prior to confirmation as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation.
