Hair testing is increasingly viewed as a robust method for identifying drug and alcohol use. Hair records a comprehensive history of substance intake by capturing biomarkers within its fibers. Collected near the scalp, hair can reveal substance use up to a roughly 3-month timeframe. The process of collecting hair is straightforward, relatively resistant to tampering, and convenient for shipping.
A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp will provide 100mg of hair, which is optimal for testing and verification. For EtG, add-ons, or analyses exceeding 10 panels, 150mg of the sample is advised. It's preferable to measure the sample's weight using a jeweler’s scale. If scalp hair isn’t available, an equivalent volume of body hair is acceptable. When we mention head hair, we refer solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into a lab's system. This step includes confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry that isn't covered by an electronic chain of custody system.
Screening constitutes a preliminary rapid evaluation for substances of abuse. While Screening is a cost-effective strategy for excluding drug use on the majority of samples, a positive result necessitates confirmation to be permissible in legal contexts. Any samples returning a presumptively positive result in Screening require a subsequent confirmation.
Upon returning a presumptive positive in the Screening phase, extra hair is extracted from the original sample, preparing it for Extraction. This phase involves retrieving drugs from hair at significantly lower concentrations compared to alternative methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo a washing process before confirmation if necessary. The full laboratory procedure, from Accessioning through Confirmation, is reviewed under the CAP (College of American Pathologists) Hair designation in addition to compliance with ISO / IEC 17025 standards.
