Hair analysis is increasingly recognized as a robust technique for uncovering drug and alcohol consumption. Hair retains a long-term record of alcohol and narcotics by embedding biomarkers within the strands as they develop. Collected near the scalp, hair can reveal substance use over a span that extends to around three months. Collection is straightforward, tampering is relatively challenging, and shipping is uncomplicated.
With a 1.5-inch hair snippet consisting of roughly 200 strands (comparable in width to a #2 pencil) from the scalp, you gather approximately 100 mg of hair, which is optimal for both testing and validation. For EtG, supplementary tests, or analyses beyond 10 panels, a 150 mg sample is advocated. The use of a jeweler's scale is advised for weighing the sample. In the absence of scalp hair, a comparable quantity of body hair is acceptable. When we mention head hair, we mean scalp hair exclusively. Body hair covers all other types (facial, axillary, etc.).
Process Overview
There are four crucial stages in the lab procedure for processing drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the initial phase where a sample enters a lab's system. This stage includes checking that the sample was sealed and transported correctly, allocating a random Laboratory Accessioning Number (LAN), and completing any further data entry absent from an electronic chain of custody protocol.
Screening serves as a preliminary rapid check for substance abuse. Despite being cost-efficient for ruling out drug use in most samples, a positive screen requires confirmation for court admissibility. Any samples presumed positive at the Screening phase must undergo additional confirmation procedures.
If a preliminary positive result arises in Screening, more hair is obtained from the original specimen for Extraction. Drugs are extracted from hair at lower concentrations than those in alternate methods (e.g., urine or saliva), which is why hair drug testing is the most intricate technique to execute.
Confirmed positive results are verified through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that preliminarily tested positive are washed before confirmation as necessary. The complete process, from Accessioning to Confirmation, is assessed for compliance with both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Despite often being called "hair follicle tests," the procedure evaluates the hair strand itself, not the follicle beneath the scalp.
