Hair analysis is increasingly recognized as a valuable method for identifying drug and alcohol consumption. Hair captures a comprehensive record of substance use by embedding biomarkers within the strands' fibers during growth. Hair samples, taken near the scalp, can reveal substance exposure for up to three months. Collecting hair is straightforward, hard to tamper with, and convenient to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp totals about 100mg, deemed the ideal quantity for preliminary and confirmatory testing. For tests like EtG, additional protocols, or beyond 10 substances, a 150mg sample is advisable. Our suggestion is to use a jeweler’s scale for precise measurement. If scalp hair is missing, equivalent body hair can be used instead. "Head hair" strictly pertains to scalp hair, whereas "body hair" encompasses other varieties (such as facial or underarm hair).
Process Overview
The typical laboratory workflow for analyzing a drug test sample involves these steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial integration of a sample into the lab's framework. This step ensures the sample's sealing and transportation were adequate, assigns a Laboratory Accessioning Number (LAN) arbitrarily, and completes any remaining data input not conveyed through an electronic chain of custody.
Screening is a preliminary, efficient analysis method to exclude drug presence in most samples. However, positive results from Screening must be substantiated for legal acceptability. Samples indicating possible drug presence in Screening necessitate further validation.
A sample with potential positive results from Screening proceeds to Extraction, using more hair from the original sample. In this phase, substances are isolated from hair with notably lower concentrations compared to methods like urine or saliva testing, which underscores the complexity of hair drug analysis.
Positive Screening results require Confirmation through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Any sample presumed positive undergoes cleansing before Confirmation, as required. The entire lab workflow, from Accessioning through Confirmation, adheres to the CAP (College of American Pathologists) criteria for Hair and ISO / IEC 17025 standards.
