Hair analysis is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair retains a long-term record of substances by capturing biomarkers within its fibers. By collecting hair near the scalp, it can reveal a substance use history spanning up to three months. Collecting hair is straightforward, relatively hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches with about 200 hair strands (approximately the width of a #2 pencil) is optimal, providing 100mg of hair, which is the ideal amount for testing. For EtG, additional tests, or tests beyond 10 panels, a 150mg sample is suggested. We advise weighing the hair on a jeweler’s scale. If scalp hair cannot be obtained, an equivalent amount of body hair is acceptable. References to head hair specifically pertain to scalp hair. Body hair denotes all other hair varieties (facial, axillary, etc.).
Process Overview
The key stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample initially enters the lab system. This step ensures the sample was properly sealed and transported, assigns it a random LAN (Laboratory Accessioning Number), and completes any extra data entry missing from an electronic chain of custody system.
Screening performs a preliminary examination for drugs of abuse. While it is a cost-effective method for excluding drug use in most samples, a positive result in Screening requires confirmation to be legally acceptable. Any samples that test positive in Screening must undergo secondary confirmation.
In cases where Screening results are positive, additional hair is taken from the initial sample to prepare it for Extraction. This phase involves extracting drugs from the hair at a much lower concentration than other methods like urine or oral fluid, which makes hair drug testing the most challenging technique to execute.
Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation if necessary. The complete lab process from Accessioning to Confirmation is audited under both the CAP Hair designation and ISO / IEC 17025 standards accreditation.
