Hair examinations have gained recognition as an effective means for identifying drug and alcohol consumption. Hair serves as a long-term archive for alcohol and other substances by trapping biomarkers within the fibers of the developing hair shaft. When taken close to the scalp, hair can yield around a 3-month period for detecting alcohol and other substances. Hair collection is straightforward, somewhat challenging to tamper with, and convenient to transport.
A 1.5-inch section of approximately 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp will accumulate 100mg of hair, which is the optimal sample size for analysis and verification. For EtG, supplemental tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest measuring the sample using a jeweler’s scale. In the absence of scalp hair, a matching amount of body hair may be utilized. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the preliminary processing of a sample into a laboratory’s system. This encompasses ensuring the sample is sealed and dispatched correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any further data entry not covered by an electronic chain of custody system.
Screening entails an initial rapid assessment for substances of abuse. Although Screening is a cost-efficient method to exclude drug usage on most samples, a positive result needs validation to be court-admissible. Any samples that give a presumptive positive result during Screening necessitate additional confirmation.
If a sample yields a presumptive positive during the Screening phase, additional hair is extracted from the original sample and processed for Extraction. During this phase, substances are extracted from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), which is why hair drug screening is considered the most labor-intensive method.
Confirmation of any Screening positive result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
