Hair analysis has been acknowledged as a robust means for uncovering drug and alcohol consumption. Hair serves as a long-standing record of alcohol and drugs by capturing biomarkers within the strands' fibers as they grow. When sourced near the scalp, hair offers approximately a three-month detection window for alcohol and drugs. Collecting hair is straightforward, fairly resistant to tampering, and convenient to send.
A 1.5-inch segment consisting of around 200 hair strands (akin to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for analysis and verification. For EtG, supplements, and/or examinations exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the sample is recommended. If scalp hair is inaccessible, a comparable amount of body hair might be obtained. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a lab’s framework. This step comprises checking that the sample was adequately sealed and transported, generating a random LAN (Laboratory Accessioning Number), and completing additional data entry absent from an electronic chain of custody system.
Screening constitutes an initial rapid evaluation for drugs of abuse. While Screening offers a cost-effective means to dismiss drug usage in most samples, confirming a positive screen is necessary for court admissibility. Any samples that are tentatively positive during Screening require a secondary confirmation.
Should a sample be tentatively positive in the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methodologies (such as urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All tentatively positive samples are cleansed before confirmation as required. The complete laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
