Hair analysis has increasingly been recognized as a robust method for detecting drug and alcohol consumption. The strands capture biomarkers within the fibers of the hair's structure, offering a lengthy timeline of substance use. When harvested near the scalp, hair can supply a detection period of up to approximately three months for alcohol and various drugs. The collection of hair is straightforward, relatively tamper-resistant, and convenient for shipping.
A 1.5-inch segment of about 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields around 100mg, which is the optimal sample size for both preliminary screening and confirmation. For EtG, additional tests, and/or analyses exceeding 10 panels, it is advised to collect 150mg of the sample. Employing a jeweler's scale to measure the specimen is recommended. If scalp hair is not available, a similar volume of body hair can be utilized. When referencing head hair, this pertains exclusively to scalp hair. Conversely, body hair encompasses all other hair forms (such as facial and axillary hair).
Process Overview
The laboratory processing of drug test outcomes involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with incorporating the sample into the lab's system. This process ensures the sample has been correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any further data entry omitted by an electronic custody chain.
Screening performs a preliminary assessment for substances of abuse. Although Screening is an economical means of excluding drug use in most samples, a positive Screening necessitates confirmation to be valid in court. Presumptive positive results from Screening require subsequent confirmation.
If a sample tests presumptively positive at Screening, additional hair is taken from the initial sample for Extraction. At this phase, substances are extracted from the hair at significantly reduced concentrations in comparison to other methods (like urine or oral fluid), which accounts for the complexity of hair drug screening.
Confirmation for any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing prior to confirmation when necessary. The complete laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
