Hair analysis is recognized as a robust method for detecting drug and alcohol use. Hair captures a lengthy history of alcohol and other substances by embedding biomarkers within the fibers of the growing strand. When clipped near the scalp, hair can offer approximately a 3-month detection period for alcohol and other drugs. Hair is easy to collect, relatively hard to tamper with, and convenient to transport.
A segment of hair 1.5 inches long consisting of approximately 200 strands (comparable to the girth of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the preferred amount for initial testing and confirmation. For EtG, additional tests, or assessments over 10 panels, 150mg of the sample is advisable. We recommend measuring the sample on a jeweler’s scale. Should scalp hair be inaccessible, a comparable quantity of body hair may be taken. By 'head hair', we mean solely scalp hair. 'Body hair' encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initiation of a sample into the laboratory's framework. This step includes verifying that the sample was securely sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and filling in any supplementary data not included in an electronic chain of custody system.
Screening entails an initial rapid drug abuse scan. Although Screening is cost-efficient for eliminating drug use in the bulk of samples, a positive screen must be substantiated for it to be valid in court. Any samples that show presumptive positivity in Screening necessitate a secondary confirmation.
If a sample evidences presumptive positivity during Screening, additional hair is extracted from the original sample and readied for Extraction. During this phase, drugs are extracted from hair at markedly lower concentrations than other methods (e.g., urine or oral fluid), underscoring why hair drug testing is the most intricate method to execute.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are purified as necessary before confirmation. The complete laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
