Hair examinations have become recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by encasing biomarkers within the structure of the hair strand as it grows. When obtained near the scalp, hair can offer up to roughly a 3-month period for alcohol and drug detection. Hair is straightforward to gather, relatively challenging to alter, and convenient to transport.
A 1.5-inch section comprising approximately 200 hair strands (equivalent to a #2 pencil) nearest to the scalp delivers 100mg of hair, the optimum sample for inspection and validation. For EtG, supplements, and/or analyses exceeding 10 panels, 150mg of the hair sample is advisable. We suggest assessing the sample with a jeweler’s scale. If scalp hair is not accessible, a comparable quantity of body hair may be obtained. In discussions of head hair, we are exclusively referring to scalp hair. Body hair pertains to all other varieties (facial, axillary, etc.).
Process Overview
The four primary phases in the laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial handling of a sample into a laboratory’s framework. This includes confirming the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not offered by an electronic chain of custody mechanism.
Screening involves an initial rapid inspection for drugs of abuse. While Screening is a cost-efficient method to dismiss drug consumption on the majority of samples, a positive screen must be authenticated to be valid in legal contexts. Any samples presumptively positive in Screening do necessitate further confirmation.
If a sample is presumptively positive in the Screening phase, additional hair is extracted from the initial specimen and prepared for Extraction. In this phase, drugs are derived from hair at a much lower concentration than in alternative methodologies (e.g., urine or oral fluid), making hair drug examination the most complex methodology to implement.
Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
