Hair analysis is recognized as a compelling approach for identifying drug and alcohol consumption. Hair captures a long-lasting record of alcohol and drug intake by embedding biomarkers in the strands as they develop. When taken close to the scalp, hair can present roughly a three-month detection timeframe for alcohol and drugs. Collecting hair is straightforward, relatively tamper-proof, and convenient to transport.
A 1.5-inch piece consisting of approximately 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for analysis and verification. For EtG, additional tests, and/or analyses exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale to weigh the sample is recommended. Should scalp hair be unavailable, a comparable quantity of body hair can be taken. "Head hair" denotes only scalp hair. "Body hair" encompasses all other varieties (facial, axillary, etc.).
Process Overview
The procedure for laboratory processing of a drug test result covers four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning necessitates the initial sample processing into a lab's framework. This process involves confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finishing any extra data entry not catered by an electronic chain of custody system.
Screening entails a quick preliminary assessment for substance abuse. Although Screening is a budget-friendly strategy for excluding drug use in most samples, a confirmed screen is essential for legal admissibility. Samples showing a presumptive positive in Screening require further confirmation.
Should a sample show presumptive positivity in the Screening phase, additional hair is retrieved from the original sample for Preparation. Drugs are separated from hair at a notably lower concentration than in other methods (e.g., urine or oral fluid), rendering hair drug analysis the most challenging procedure to execute.
A positive screening outcome undergoes Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before Confirmation as necessary. The comprehensive lab approach from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 standard accreditation.
