Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering a prolonged trace of alcohol and drugs. When gathered from near the scalp, hair can offer a detection timeline of up to roughly 3 months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A sample measuring 1.5 inches and containing around 200 hair strands (comparable to a #2 pencil thickness) near the scalp yields 100mg of hair, the optimal amount for testing. For EtG, additional analyses, or tests exceeding 10 panels, 150mg is advised. We suggest using a jeweler's scale for weighing. If scalp hair is not available, a similar quantity of body hair can be used. "Head hair" refers exclusively to scalp hair, while "body hair" includes all other hair forms (facial, axillary, etc.).
Process Overview
Drug test result processing involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails incorporating a sample into the laboratory’s workflow. This phase ensures the sample has been securely sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and encompasses any supplementary data input absent from an electronic custody system.
Screening is a preliminary examination for drug presence. It is a cost-effective approach for dismissing drug usage in most samples, though any positive finding needs confirmation before court admissibility. Samples flagged as potentially positive in Screening require follow-up confirmation.
In cases of tentative positive results in Screening, additional hair is taken from the initial sample for Extraction. Drugs are extracted from hair at concentrations significantly lower than those in alternative methods (e.g., urine or oral fluid), making hair drug screening the most intricate methodology.
To validate any positive results from screening, techniques like GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples that initially test positive undergo washing prior to final confirmation. The comprehensive lab routine, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation criteria.
