Hair testing has emerged as a potent method for identifying drug and alcohol consumption. Hair retains a comprehensive history of alcohol and other drugs by embedding biomarkers within the fibers of the growing strand. When sampled near the scalp, hair can offer a detection window up to around three months for alcohol and other substances. Collecting hair is straightforward, somewhat resistant to tampering, and convenient for transport.
A sample of 1.5 inches comprising around 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp provides 100mg, an exemplary quantity for analysis and validation. For EtG, add-ons, and/or analyses exceeding 10 panels, a sample of 150mg is advised. We suggest using a jeweler’s scale to measure the specimen. If scalp hair is inaccessible, an equivalent amount of body hair can be utilized. When discussing head hair, we specifically mean scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The principal stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial management of a sample in a lab's framework. This includes validating that the sample was securely sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input not facilitated by an electronic chain of custody protocol.
Screening consists of an initial rapid assessment for drugs of misuse. Although Screening is an economical approach to exclude drug usage in numerous samples, a confirmed positive screen is necessary for legal proceedings. Samples that screen presumptively positive do require an additional confirmation step.
If a sample is provisionally positive in the Screening phase, additional hair is taken from the original sample and processed for Extraction. During this phase, drugs are extracted from hair in considerably lower concentrations than through other techniques (e.g., urine or oral fluid), which is why hair drug screening is the most intricate methodology to undertake.
Verification of any positive screening outcome is done through GC/MS, GC/MS/MS, or LC/MS/MS. All tentatively positive samples undergo washing before verification as required. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
