Hair testing has emerged as an effective instrument for identifying drug and alcohol consumption. Hair offers a comprehensive history of alcohol and drug intake by embedding biomarkers within the fibers of the growing hair shaft. When gathered near the scalp, it can reveal a detection timeframe of up to three months for alcohol and other substances. Hair is easy to obtain, relatively resistant to tampering, and simple to transport.
A 1.5-inch hair specimen, consisting of approximately 200 strands (comparable to a #2 pencil in thickness), will yield 100mg of hair, which is the optimal sample for preliminary screening and confirmation. For EtG, add-ons, and/or assessments exceeding 10 panels, 150mg of the specimen is advisable. It's suggested to measure the sample using a jeweler’s scale. In the absence of scalp hair, a corresponding quantity of body hair can be used. When mentioning head hair, it pertains strictly to scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The key stages in laboratory processing for a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with integrating a sample into a lab’s system. This process verifies appropriate sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and performs any supplementary data entry absent from an electronic chain of custody system.
Screening undertakes an initial rapid check for drug abuse. Although Screening is a cost-efficient mechanism to exclude drug use in most samples, any positive screen requires confirmation for court admissibility. Samples with presumptive positivity during Screening must undergo a secondary confirmation.
Should a sample be presumptively positive in the Screening phase, additional hair is extracted from the initial sample and prepped for Extraction. Here, drugs are retrieved from hair at a significantly lower concentration compared to other methods (e.g., urine or saliva), rendering hair drug screening the most challenging methodology to execute.
The Confirmation of any positive Screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as necessary. The entire lab process from Accessioning to Confirmation is evaluated under the standards of both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
