Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Offering an extended timeline of substance use, hair captures biomarkers within its growing strand fibers. When gathered near the scalp, it can offer up to a 3-month detection period for alcohol and drugs. The collection process for hair is straightforward, with challenges in tampering and easy in shipping.
A 1.5-inch segment of roughly 200 hair strands (approximately the size of a standard pencil) nearest the scalp yields 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is advised. It is suggested to measure the specimen using a jeweler's scale. If head hair isn't accessible, a comparable amount of body hair can be obtained. "Head hair" specifically indicates scalp hair, while "body hair" encompasses all other varieties (such as facial or axillary hair).
Process Overview
The principal stages in the lab procedure for processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial phase of incorporating a sample into the laboratory's framework. It also entails checking that the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not provided by an electronic chain of custody system.
Screening serves as a preliminary rapid assessment for drugs of abuse. While Screening offers a cost-effective approach to exclude drug use in most samples, a positive screen requires confirmation to be valid in legal proceedings. Any samples testing presumptively positive during Screening must undergo a secondary confirmation process.
When a sample exhibits presumptive positivity in Screening, more hair is extracted from the original specimen and prepared for Extraction. During this phase, hair is subjected to drug extraction at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), explaining the complexity of hair drug screening as a methodology.
Confirmed positive results from Screening are validated via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The entire laboratory workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often termed as "hair follicle tests," the actual examination focuses on analyzing the hair strand rather than the follicle below the scalp.
