Hair analysis is widely recognized for its effectiveness in identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and substance use by embedding biomarkers within its developing strands. When sourced near the scalp, hair can reveal drug and alcohol presence for up to a three-month timeframe. Hair collection is straightforward, though tough to alter, and convenient for shipping.
A 1.5-inch segment of around 200 hair strands (approximately as thick as a #2 pencil) nearest to the scalp can yield 100mg, ideal for both screening and confirmatory testing. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale for the specimen’s weight is recommended. If scalp hair is unavailable, an equal amount of body hair is an alternative. “Head hair†denotes scalp hair exclusively, while “body hair†encompasses all other variations (facial, axillary, etc.).
Process Overview
The primary laboratory procedures for drug test results comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating a sample into a lab’s system at the outset. This process ensures proper sealing and shipping of samples, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any incomplete data entry absent from an electronic chain of custody.
Screening offers an initial rapid assessment for drug abuse presence. While cost-efficient in typically negating drug use in most samples, positive screenings mandate confirmation for court eligibility. Any samples with a presumptive positive Screening necessitate further validation.
For presumptive positives during Screening, additional hair is extracted from the initial sample to prepare for Extraction. Drugs are isolated from hair in this phase at notably lower concentrations than other methods (e.g., urine or oral fluid), establishing hair drug testing as the most complex methodology to conduct.
Confirmation of positive screenings utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumed positive samples undergo washing prior to necessary Confirmations. The entire lab procedure from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
