Hair analysis has emerged as an effective means for identifying substance use, providing a comprehensive historical record of alcohol and drug consumption by embedding biomarkers within the hair strand fibers. Collected near the scalp, hair can reveal substance use over a span of up to three months. It's easily collected, relatively hard to tamper with, and simple to transport.
A 1.5-inch section comprising approximately 200 hair strands (equivalent to the thickness of a #2 pencil) nearest the scalp yields about 100mg, which is ideal for both screening and validation. For EtG, additional tests, and assessments exceeding 10 panels, 150mg of hair is advisable. We suggest using a jeweler's scale to measure the specimen weight. In cases where scalp hair isn't available, an equal quantity of body hair can be used. When discussing head hair, we specifically mean scalp hair, while body hair encompasses other types including facial and axillary hair.
Process Overview
The core steps in processing a drug test result at the laboratory are: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a sample into a lab's system. This involves checking that the sample is properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data input absent from an electronic chain of custody system.
Screening performs an initial rapid examination for substances. While it's a budget-friendly method to dismiss substance use for most samples, any positive screen needs further verification for court admissibility. Presumptive positives from Screening require secondary confirmation.
For samples with presumptive positive results at the Screening stage, additional hair is extracted from the original sample for the Extraction process. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most challenging method to execute.
Confirmation of any positive result from the Screening is done via GC/MS, GC/MS/MS, or LC/MS/MS. Preliminary positive samples undergo washing before confirmation if necessary. The entire laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.
