Hair testing has evolved into a potent means for uncovering drug and alcohol consumption habits. Hair offers an extended timeline of alcohol and drug activity by capturing biomarkers within the fibers of the growing hair strand. When obtained from near the scalp, hair can reveal a detection window spanning up to three months for alcohol and drugs. Hair collection is straightforward, not easily tampered with, and convenient for shipping.
A 1.5-inch section with around 200 hair strands (comparable to a #2 pencil in diameter) nearest to the scalp provides 100mg of hair, an ideal sample size for screening and verification. For tests like EtG, additional panels, or those exceeding 10 panels, a sample of 150mg is advised. It's best to weigh the sample using a jeweler’s scale. If scalp hair is lacking, a similar amount of body hair can be used. 'Head hair' in this context refers exclusively to scalp hair, while 'body hair' encompasses all other hair forms (e.g., facial, axillary).
Process Overview
There are four primary stages in the laboratory handling of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the first step of incorporating a sample into a lab's system. This stage verifies that the sample was properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and includes any additional information not available electronically through a chain of custody.
Screening involves a preliminary assessment for drugs of abuse. Although it is a cost-efficient approach to exclude drug usage in the majority of cases, a positive screening requires verification to be legally acceptable. Samples showing preliminary positive results in Screening necessitate additional confirmation.
For samples showing potential positivity in the Screening phase, extra hair is extracted from the initial sample and prepared for Extraction. This phase involves extracting drugs from hair at concentrations much lower than in other methods (such as urine or oral fluid), making hair drug screening the most challenging method to execute.
Positive results from Screening are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a washing process if needed before confirmation. The full lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and in accordance with ISO / IEC 17025 standards.
