Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. The long-term record of drug and alcohol use is captured as biomarkers within the hair strand’s growing fibers. When acquired near the scalp, hair offers a detection period of roughly three months for alcohol and other drugs. The collection of hair is straightforward, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches and comprising around 200 hair strands (approximating the width of a #2 pencil) nearest to the scalp yields 100mg, an ideal amount for screening and verifying. For EtG, additional tests, or tests exceeding 10 panels, a specimen of 150mg is suggested. Employ a jeweler’s scale for precise specimen weighing. If scalp hair is missing, an equivalent quantity of body hair can be sourced. Reference to head hair pertains solely to scalp hair. In contrast, body hair encompasses all other types, such as facial and axillary hair.
Process Overview
The laboratory process of analyzing a drug test result incorporates the key steps of Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the foremost handling of a sample within a lab's framework. It verifies that the sample was adequately sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and completes any requisite documentation absent from an electronic chain of custody system.
Screening provides an initial swift evaluation for drug misuse. Though cost-effective for discarding drug use in most cases, a positive screen necessitates confirmation for legal acceptability. Samples deemed presumptively positive via Screening mandate a further confirmation step.
For samples flagged as presumptively positive in the Screening phase, additional hair is curated from the initial sample for Extraction. This step retrieves drugs at notably lower concentrations than alternative methods (e.g., urine or oral fluids), establishing hair drug screening as the most challenging technique to execute.
Positive screening outcomes undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptively positive samples are cleansed before confirmation, as needed. The comprehensive lab process from Accessioning to Confirmation adheres to standards by both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.
