Hair examinations have emerged as an effective method for identifying drug and alcohol consumption. Hair stores a comprehensive record of substance use by embedding biomarkers within the fibers of the developing hair shaft. When collected close to the scalp, it offers a detection period of up to three months for both alcohol and drugs. The collection process is straightforward, relatively tamper-resistant, and easy to transport.
Collecting a 1.5-inch segment of approximately 200 hair strands (similar in size to a #2 pencil) nearest the scalp yields 100mg of hair, suitable for screening and confirmation. For EtG, additional tests, and/or panels exceeding ten, a 150mg sample is advisable. Utilizing a jeweler's scale to weigh the sample is suggested. Should scalp hair be unavailable, an equivalent volume of body hair may be used. "Head hair" specifically refers to scalp hair, whereas "body hair" includes all other kinds (such as facial or axillary).
Process Overview
The four key steps in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the lab's workflow. This stage involves confirming that the sample remains sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry omitted by an electronic chain of custody system.
Screening performs an initial rapid assessment for substance abuse. Although Screening is an economical method to dismiss drug use in most samples, a positive finding necessitates confirmation for legal admissibility. Any samples with an assumed positive result in Screening require subsequent confirmation.
For samples with presumed positivity in Screening, extra hair is extracted from the original specimen and readied for Extraction. In this stage, drugs are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), explaining why hair drug screening poses greater challenges in execution.
Verification of any positive screening finding is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a washing process before confirmation, if necessary. The comprehensive laboratory process, from Accessioning to Confirmation, is assessed following both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
