Hair testing is recognized as an effective method for uncovering drug and alcohol consumption. It provides a comprehensive history by embedding biomarkers within the strands. Particularly when taken near the root, a hair sample can reveal substance use over a period of roughly 90 days. It’s easy to obtain, hard to tamper with, and straightforward to transport.
An ideal specimen involves a 1.5-inch cut of roughly 200 hairs (similar to a #2 pencil's thickness) closest to the scalp, yielding 100mg, which is optimal for thorough analysis. For tests such as EtG, additional panels, or those exceeding 10, 150mg of hair is advised. It's recommended to verify the weight using a jeweler’s scale. Should scalp hair be inaccessible, equivalent body hair may be substituted. “Scalp hair” pertains solely to hair from the head, whereas “body hair” includes other types (e.g., facial, axillary).
Process Overview
There are four primary steps in processing a drug test in the lab: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary incorporation of the sample into the laboratory’s workflow. This involves ensuring the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and supplementing any lacking data not captured electronically.
Screening offers a preliminary assessment for substance presence. Although cost-efficient and useful for eliminating drug use in many cases, a positive result necessitates further verification for legal reliability. Any presumptive positive in Screening mandates secondary Confirmation.
During the Extraction phase, if initial Screening indicates potential positivity, additional hair is extracted and processed. Here, substances are isolated at notably lower concentrations compared to other methods (such as urine or oral fluids), highlighting the advanced difficulty of hair drug tests.
For any positive outcomes in Screening, Confirmation is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed before confirmation as appropriate. The entire testing process, from Accessioning through Confirmation, is scrutinized per the CAP (College of American Pathologists) Hair protocols, ensuring alignment with ISO / IEC 17025 standards.
