Hair analysis has become a recognized method for identifying drug and alcohol consumption. Hair captures biomarkers within the strands of hair as they grow, offering a long-term history of substance use. Samples gathered near the scalp can reveal up to a 3-month period of drug or alcohol use. Hair collection is straightforward, difficult to tamper with, and convenient to transport.
A 1.5-inch sample from roughly 200 hair strands, comparable to the width of a #2 pencil, near the scalp yields 100mg, ideal for evaluating and confirming. For EtG, additional tests, or analyses beyond 10 panels, 150mg of sample is advised. We suggest using a jeweler’s scale for weight accuracy. If scalp hair isn’t available, an equal measure of body hair can be used. Our reference to head hair strictly denotes scalp hair, while body hair includes all other types (facial, armpit, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary insertion of a sample into a laboratory’s system. This step includes ensuring the sample’s packaging and delivery were correct, assigning a random LAN (Laboratory Accessioning Number), and handling any additional data entry that wasn’t provided by an electronic chain of custody system.
Screening acts as an initial assessment for drug presence. Although Screening offers a cost-effective means to discount drug usage in most samples, a positive result necessitates confirmation for court admissibility. Samples that test as presumptive positive in Screening require a further confirmation process.
For samples testing positive at the Screening stage, more hair from the sample is processed for Extraction. Here, drugs are extracted from hair at notably lower concentrations than those in other methods (e.g., urine or oral fluid), thus making hair drug screening a challenging methodology to execute.
The Confirmation phase for any positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples marked as presumptive positive are rinsed before proceeding to confirmation if necessary. The laboratory workflow from Accessioning to Confirmation is governed by both the College of American Pathologists (CAP) Hair designation and the compliance with ISO / IEC 17025 standards.
