Hair analysis emerges as an effective instrument for detecting alcohol and drug consumption. Hair captures a lengthy history of drugs and alcohol by embedding biomarkers within the fibers of the hair as it grows. When hair is collected from near the scalp, it affords nearly a 3-month detection span for alcohol and drugs. Collection of hair is easy, comparatively hard to tamper with, and simple to transport.
Collecting a 1.5-inch segment of around 200 hair strands (roughly the girth of a #2 pencil) nearest the scalp yields 100mg of hair, the preferred amount for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg specimen is advised. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair isn’t an option, collecting an equivalent amount of body hair is acceptable. By head hair, we specifically mean scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The core steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample first enters a laboratory’s system. This step involves ensuring the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and entering any extra data not available through an electronic chain of custody.
Screening is a preliminary rapid assessment for substances of abuse. Although cost-effective for eliminating drug use in most samples, a positive result in Screening requires confirmation for court acceptance. Any samples indicated as positive in Screening demand a confirmation step.
If Screening indicates a presumptive positive, additional hair is extracted from the initial sample and prepped for Extraction. This stage involves retrieving drugs from hair at significantly lower concentrations in comparison to other methods (such as urine or oral fluid), which makes hair drug testing a challenging practice.
Confirmation for any positive Screening outcome is accomplished with GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed prior to confirmation as required. The complete lab procedure from Accessioning to Confirmation is evaluated through both the CAP (College of American Pathologists) Hair designation and according to ISO / IEC 17025 standards.
