Hair examinations are increasingly recognized as an effective method for identifying drug and alcohol consumption. By embedding biomarkers within the strands during hair growth, hair offers an extended history of substance use. When taken near the scalp, it can reveal usage within roughly a 3-month timeframe for alcohol and drugs. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A sample of 1.5 inches consisting of around 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp yields approximately 100mg—ideal for analyses. For EtG, additional checks, or tests exceeding 10 panels, a specimen of 150mg is advised. Utilizing a jeweler’s scale for weighing is suggested. In instances where scalp hair isn't present, an equivalent quantity of body hair might be used. Whenever mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
Key stages in lab processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a lab's system, verifying proper sealing and shipment, assigning a LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody.
Screening comprises an initial rapid assessment for substance abuse. While it is cost-efficient for eliminating drug use in the majority of samples, a positive result requires confirmation for court acceptance. Any samples showing a presumptive positive in Screening necessitate secondary verification.
Should a sample show a presumptive positive at Screening, additional hair is extracted from the original specimen for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug analysis the most complex method.
Confirmation for any positive Screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleansed before confirmation as needed. The entire lab procedure from Accessioning to Confirmation is rigorously examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
