Hair analysis is now regarded as an effective method for detecting drug and alcohol consumption. Hair retains a historical record of alcohol and drug use by embedding biomarkers within the developing hair strand. When collected near the scalp, hair offers a detection timeframe of nearly three months for alcohol and drugs. Hair is straightforward to collect, challenging to tamper with, and simple to transport.
A hair sample measuring 1.5 inches, consisting of around 200 strands (comparable to the diameter of a #2 pencil) near the scalp provides 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG, supplementary tests, and/or analyses beyond 10 panels, a 150mg specimen is advised. Using a jeweler's scale for weighing the sample is recommended. In cases where scalp hair isn't available, an equivalent quantity of body hair may be used. "Head hair" pertains only to scalp hair, while "body hair" includes all other hair types, such as facial or axillary hair.
Process Overview
The key phases in the lab processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing step, incorporating the sample into a lab's system. This phase ensures the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finalizes any data entries missing from an electronic chain of custody system.
Screening provides an initial assessment for drugs of abuse. While cost-effective for negating drug use in most samples, a positive screen requires verification to be permissible in court. Any samples that preliminarily test positive in Screening require subsequent confirmation.
Should a sample initially test positive during Screening, additional hair is taken from the original sample for the Extraction phase. Here, drugs are extracted from hair in much lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening as the most complex to perform.
Confirming positive screening results is achieved using GC/MS, GC/MS/MS or LC/MS/MS methods. Any potentially positive samples are cleansed before confirmation if necessary. The full laboratory procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
