Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. Hair archives a prolonged record of substance use by encapsulating biomarkers within the fibers of the growing strand. When clipped near the scalp, hair can offer an approximately 3-month timeframe for detecting alcohol and drugs. It is straightforward to collect, hard to tamper with, and convenient to transport.
A 1.5-inch clipping of around 200 hairs (about the thickness of a #2 pencil) nearest to the scalp will provide 100mg of hair, the preferred sample size for analysis and verification. For EtG, supplementary tests, and/or screenings beyond 10 panels, a 150mg sample is advisable. We advise measuring the sample on a jeweler’s scale. If head hair is absent, a corresponding quantity of body hair can be obtained. When referencing head hair, we specifically mean scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The primary phases involved in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial entry of a sample into the laboratory's system. This process ensures the sample was correctly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and completes any extra data input not covered by an electronic chain of custody system.
Screening entails an initial rapid test for drugs of abuse. While Screening is a cost-effective strategy to exclude drug use in most samples, a positive result must be confirmed for it to be valid in court. Any samples showing a presumptive positive during Screening require further confirmation.
Should a sample exhibit a presumptive positive result at the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are drawn from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), which is why hair drug assessment is the most challenging technique to execute.
Confirmation of any positive Screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing prior to confirmation if needed. The entire lab procedure from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO/IEC 17025 standards.
