Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a chronological record of substances by embedding biomarkers within the fibers of the growing hair shaft. A sample collected near the scalp reveals a detection window of up to roughly three months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and convenient for transportation.
A sample of 1.5 inches consisting of about 200 hair strands (comparable to the diameter of a #2 pencil) from the scalp will yield 100mg of hair, which is optimal for evaluation and verification. For tests involving EtG, additional screens, and/or tests over 10 panels require 150mg of the specimen. Utilize a jeweler’s scale for accurate specimen measurement. If scalp hair isn’t available, an equivalent quantity of body hair can be used. The term "head hair" refers exclusively to scalp hair, whereas "body hair" encompasses all other types (such as facial and axillary hair).
Process Overview
The laboratory process for achieving a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating a sample into the laboratory’s system. Tasks include confirming the sample’s proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing supplementary data entry not managed by an electronic chain of custody system.
Screening provides an initial assessment for drug presence. While this preliminary screening is an economical method to exclude drug use in most instances, confirmed positives are necessary for court acceptance. Samples identified as presumptively positive in Screening need subsequent confirmation.
If a sample tests preliminarily positive in the Screening phase, additional hair is extracted from the specimen for the Extraction process. Here, drugs are isolated from hair at concentrations significantly lower than those used in other techniques (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
GC/MS, GC/MS/MS, or LC/MS/MS methods confirm any positive screening results. Presumptive positive samples undergo necessary cleansing before confirmation. The full lab procedure from Accessioning to Confirmation is evaluated under the standards of the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
