Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair captures extended histories of alcohol and other substances by securing biomarkers within the strands as they grow. When sampled near the scalp, hair can reveal usage for about a 90-day duration for alcohol and other drugs. Collecting hair is straightforward, not easily tampered with, and convenient to transport.
An ideal sample consists of a 1.5-inch section of approximately 200 hair strands (comparable in size to a #2 pencil) close to the scalp, providing 100mg of hair for optimal screening and confirmation. For EtG, extensions, and/or tests exceeding 10 panels, a specimen weight of 150mg is suggested. We advise using a jeweler’s scale to measure the sample. If scalp hair isn’t accessible, an equivalent amount of body hair can be utilized. The term "head hair" specifically denotes scalp hair only. "Body hair" includes all other hair types (facial, axillary, etc.).
Procedure Summary
Laboratory processing in drug testing involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, involving the integration of a sample into a laboratory’s system. This step ensures the sample was properly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not accounted for by an electronic chain of custody system.
Screening performs an initial rapid assessment for substances of abuse. While Screening is cost-efficient for excluding drug usage in most samples, any positive screening results must be verified for legal admissibility. Samples with presumptive positives in Screening require subsequent confirmation.
For samples showing presumptive positives during Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are isolated from hair at much lower levels than in other techniques (e.g., urine or oral fluid), explaining why hair drug screening presents a significant challenge methodologically.
Confirmation of any positive screening result employs techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as necessary. The laboratory process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 norms.
