Hair analysis has emerged as a potent means for identifying substance and alcohol consumption. Hair strands capture biomarkers from drugs and alcohol within the fibers over an extended period. When samples are taken near the scalp, they can reveal consumption over a period of almost three months. The collection of hair samples is straightforward, challenging to tamper with, and straightforward to transport.
Collecting a 1.5-inch hair section consisting of 200 strands (approximately the thickness of a #2 pencil) close to the scalp yields 100mg of hair, which is optimal for initial and confirmatory analysis. For EtG, additional tests, or those exceeding 10 panels, a specimen of 150mg is suggested. It's advisable to use a jeweler’s scale to weigh the specimen. If scalp hair is not accessible, a similar quantity of body hair is acceptable. Mention of head hair refers exclusively to scalp hair, while body hair includes other hair forms (like facial or axillary).
Overview of the Process
The processing of a laboratory drug test result comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes primary processing into the lab’s system. This step ensures the sample was properly sealed and dispatched, assigns a LAN (Laboratory Accessioning Number), and completes any outstanding data entries that weren’t provided through an electronic chain of custody system.
Screening acts as an initial evaluation for substance misuse. Though cost-efficient for eliminating drug usage in most samples, a positive screen necessitates further confirmation to be valid in legal contexts. Samples that are potentially positive in Screening require an additional confirmation test.
If a sample shows a presumptive positive result during Screening, additional hair is extracted for the Extraction phase. This involves retrieving drugs from hair at notably lower concentrations compared to other methods (like urine or oral fluid), underscoring the complexity of hair drug analysis.
Positive screening outcomes are verified using GC/MS, GC/MS/MS or LC/MS/MS. Samples presumed positive are washed prior to confirmation, if necessary. The complete lab procedure, from Accessioning to Confirmation, aligns with both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 standards.
