Hair analysis is now regarded as an effective method for identifying drug and alcohol use. Hair demonstrates a prolonged history of alcohol and drug intake by encapsulating biomarkers within the strands as they grow. When taken near the scalp, a hair test can offer a detection window of up to three months for alcohol and drugs. Hair collection is straightforward, difficult to tamper with, and easy to transport.
A 1.5-inch snippet of roughly 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp provides 100mg of hair, the perfect sample for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg is advised. It is suggested to weigh the sample on a jeweler’s scale. If scalp hair isn’t present, equivalent body hair might be used. Head hair specifically refers to scalp hair, whereas body hair covers all other types (facial, underarm, etc.).
Process Overview
The primary phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of entering a sample into the lab’s database. It comprises checking if the sample was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and finishing any additional data entry absent from an e-chain of custody system.
Screening is a preliminary fast assessment for drug abuse. Although Screening is a budget-friendly approach to discard drug use in most samples, any positive screen calls for confirmation before being court-admissible. Samples that test positive in Screening necessitate further confirmation.
Upon a presumptive positive in Screening, extra hair is extracted from the initial sample for Extraction. Here, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine, oral fluid), making hair drug screening a challenging methodology to execute.
All positive screening outcomes are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed pre-confirmation if needed. The full lab process from Accessioning to Confirmation complies with both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation standards.
