Hair analysis is now recognized as an efficient means to identify drug and alcohol usage. Hair captures a long-term record of alcohol and drug consumption by embedding biomarkers within the strands of growing hair. When obtained near the scalp, hair can offer roughly a 3-month window for identifying alcohol and drug presence. Hair collection is straightforward, posing little risk of tampering, and is convenient to transport.
A sample of 1.5 inches comprising around 200 hair strands (equivalent to the girth of a #2 pencil) nearest to the scalp delivers 100mg of hair, which is the optimal quantity for both screening and validation. For testing EtG, additional panels, and/or over 10 panels, 150mg of the sample is advisable. It's suggested to measure the sample using a jeweler’s scale. Should scalp hair be unattainable, an equivalent amount of body hair is a viable alternative. The term head hair specifically denotes scalp hair, while body hair encompasses all other hair categories (like facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary processing of a sample into a lab's system. It ensures that the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not provided by an electronic chain of custody system.
Screening offers an initial rapid assessment for drugs of abuse. Although Screening cost-effectively excludes drug usage in most cases, a positive screen must be confirmed to be legally valid. Samples that are suspected positive during Screening require secondary confirmation.
In cases where a sample is suspected positive during Screening, additional hair is taken from the primary specimen for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug analysis the most challenging method to conduct.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All presumptively positive samples undergo a washing process before confirmation as needed. The complete laboratory journey from Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
