Hair analysis has evolved into a significant method for identifying drug and alcohol consumption. Hair retains a long-term profile of alcohol and narcotics by capturing biomarkers within the fibers of the maturing hair shaft. When samples are taken close to the scalp, they can offer a detection range of up to roughly 90 days for alcohol and drugs. This type of test is straightforward to collect, comparatively challenging to tamper with, and easy to transport.
A 1.5-inch section consisting of about 200 hair strands (roughly the thickness of a #2 pencil) from the scalp will provide 100mg of hair, which is the preferred amount for both initial screens and confirmations. For EtG, additional checks, and/or tests beyond 10 panels, 150mg of hair is suggested. Using a jeweler’s scale is advised for weighing the sample. If scalp hair isn’t available, a similar quantity of body hair can be used. 'Head hair' refers solely to scalp hair, whereas 'body hair' includes all other types (such as facial, axillary, etc.).
Process Overview
The processing of drug test outcomes in a laboratory follows four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the start of integrating a sample into a lab’s database. This step verifies that the sample was correctly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional entry not covered by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for drug abuse. Although Screening is a cost-efficient method to dismiss drug use in most samples, a positive result requires confirmation for legal acceptability. Any sample that tests potentially positive during Screening mandates a follow-up confirmation.
If a sample shows a positive indication in the Screening phase, extra hair is extracted from the initial sample pile and readied for Extraction. During this phase, drugs are extracted from hair at a much lower concentration compared to other techniques (like urine or oral fluid analyses), highlighting why hair drug testing is among the most complex techniques to execute.
Positive results from Screening are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing before confirmation if required. The comprehensive laboratory workflow from Accessioning through Confirmation is reviewed under both the CAP (College of American Pathologists) Hair guidelines and compliance with ISO / IEC 17025 certification.
