Hair analysis is widely recognized as an effective means of detecting drug and alcohol consumption. By embedding biomarkers within the growing hair fibers, hair offers an indelible record of substance use over time. When sourced near the scalp, hair can reveal up to a three-month history of alcohol and drug presence. The collection process is straightforward, tampering is relatively challenging, and shipping is uncomplicated.
A sample of 1.5 inches of around 200 hair strands (similar to the diameter of a #2 pencil) taken from the scalp yields 100mg of hair, which is ideal for preliminary testing and detailed analysis. For testing that includes EtG, additional criteria, or extends beyond 10 panels, a sample size of 150mg is advised. Utilizing a jeweler's scale to measure the specimen is recommended. Should scalp hair not be accessible, an equivalent volume of body hair is permissible. References to head hair pertain exclusively to scalp hair, while body hair encompasses all other forms, including facial and axillary hair.
Process Overview
The sequence of steps integral to laboratory drug test analysis encompasses Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initiation of a sample into the laboratory system. This involves confirming the sample was properly sealed and sent, assigning a random Laboratory Accessioning Number (LAN), and completing any requisite data entry absent from an electronic chain of custody protocol.
Screening incorporates an initial assessment for drugs of abuse. Serving as a cost-effective measure to exclude drug usage in the majority of cases, a positive screen mandates confirmation for legal admissibility. Any samples indicating a presumptive positive in Screening necessitate further confirmation.
Should Screening yield a presumptive positive, additional hair is extracted from the initial sample and made ready for the Extraction phase. Here, drugs are derived from hair at concentrations markedly lower than in other methods (e.g., urine or oral fluid), underscoring the challenge of hair drug screening.
Confirmation of a positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Every positive indication necessitates that samples undergo washing before confirmation if required. The complete laboratory process, from Accessioning through Confirmation, adheres to the CAP Hair designation and ISO/IEC 17025 accreditation standards.
