Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair fibers capture biomarkers of alcohol and drugs, providing an extended usage history. When strands are acquired near the scalp, they offer a detection window of up to around 3 months for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil's width) closest to the scalp would yield approximately 100mg, which is the optimal sample for both screening and confirmation. For EtG, additional tests, or tests over 10 panels, a recommendation of 150mg of the sample is suggested. It's advisable to weigh the sample using a jeweler's scale. If scalp hair is not accessible, a comparable quantity of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" pertains to all other hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, involving the integration of a sample into the lab system. The process confirms the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finishes any extra data input not available through an electronic chain of custody system.
Screening is an initial rapid assessment for drug abuse. While cost-efficient for excluding drug usage in most samples, a positive finding in Screening needs confirmation to be valid in a legal setting. Any samples showing presumptive positives in Screening need further confirmation.
If Screening shows a sample as presumptively positive, extra hair is taken from the original specimen and prepped for Extraction. Drugs are extracted from hair here at significantly lower concentrations than other methods (such as urine or oral fluid), highlighting the challenge of hair drug testing.
Any positive result from Screening is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo cleaning before confirmation as required. The progression from Accessioning to Confirmation is overseen under the CAP (College of American Pathologists) Hair designation and follows accreditation to ISO / IEC 17025 standards.
