Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. It offers an extended history of substance use because specific biomarkers become encased within the fibers of growing hair. When gathered near the scalp, hair allows for a detection timeframe of up to three months for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.
A hair sample measuring 1.5 inches and consisting of roughly 200 strands (akin to the size of a #2 pencil) collected nearest to the scalp yields 100mg of hair, which is the ideal amount for both preliminary and confirmatory analysis. For EtG, additional testing, and/or tests involving more than 10 panels, 150mg of hair is suggested. The sample should be weighed using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent amount of body hair can be used. References to head hair pertain exclusively to scalp hair, while body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result includes four critical stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample undergoes preliminary processing within a laboratory system. This entails ensuring the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not supplied by an electronic chain of custody system.
Screening involves a preliminary assessment for substances of abuse. While Screening offers a cost-effective means to negate drug use for most samples, any positive screen must be confirmed to be valid in legal settings. Samples that are initially presumptive positive in Screening require further confirmation.
Should a specimen show presumptive positivity in the Screening phase, additional hair is extracted from the original sample for Extraction. During this process, substances are extracted from hair at significantly lower concentrations compared to other methods (like urine or oral fluids), which highlights the complexity of hair drug testing.
Confirmation of any positive Screening outcome is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo washing before confirmation if necessary. The overall laboratory procedure from Accessioning to Confirmation is evaluated following CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests", the procedure analyzes the hair strand itself, not the hair follicle beneath the scalp.
