Hair analysis is now recognized as an effective method for detecting drug and alcohol consumption. Hair offers a detailed record of drugs and alcohol by capturing biomarkers within the structures of the continuously elongating hair fiber. Hair samples, when cut close to the scalp, offer a substance history stretching back up to three months for drugs and alcohol. The collection process is straightforward, the potential for tampering is low, and samples are easily sent for testing.
A collection of 1.5 inches from around 200 hair strands (comparable to a #2 pencil in thickness) nearest the scalp produces 100mg of hair, the preferred sample size for analysis and validation. For tests involving EtG, additional screening, or more than 10-panel testing, 150mg is suggested. It is advisable to measure the sample using a jeweler’s scale. Should scalp hair not be present, an equivalent quantity of body hair can be obtained. Head hair refers exclusively to scalp hair. In contrast, body hair includes all other hair types (such as facial and underarm hair).
Process Overview
There are four primary stages in the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage of integrating a sample into a lab’s framework. This stage ensures that the sample has been correctly sealed and sent, allocates a random LAN (Laborary Accessioning Number), and finalizes any extra data not supplied by an electronic chain of custody system.
Screening performs a preliminary rapid assessment for substance abuse. While Screening offers a cost-efficient way to exclude drug use across many samples, a positive result requires verification to be court-admissible. Samples with a preliminary positive in Screening need further confirmation.
Once a sample shows a preliminary positive during Screening, additional hair is extracted from the initial batch and set for Extraction. This stage involves procuring drugs from the hair at concentrations lower than those in other techniques (e.g., urine or salivary testing), making hair drug testing a more challenging method to execute.
Verification of any positive screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples showing preliminary positives are adequately cleansed before verification if required. The entire lab procedure from Accessioning to Confirmation adheres to the guidelines of the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation criteria.
