Hair testing has emerged as a significant method for identifying drug and alcohol usage. Hair retains a prolonged history of alcohol and drug consumption by enclosing biomarkers within its strands. When gathered near the scalp, hair can offer up to a 3-month period for detecting alcohol and drugs. It's easy to collect, challenging to tamper with, and convenient to transport.
A 1.5-inch section consisting of around 200 hair strands, comparable in size to a #2 pencil and situated nearest to the scalp, yields 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional panels, or tests exceeding 10 panels, 150mg of the specimen is advised. Utilizing a jeweler’s scale is recommended for weighing the specimen. If scalp hair is unobtainable, an equivalent portion of body hair may be used. References to head hair specifically mean scalp hair. Body hair encompasses all other types (such as facial or axillary).
Process Overview
The laboratory processing of drug test results encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the laboratory system. Tasks include verifying the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry that an electronic chain of custody system hasn't provided.
Screening entails a preliminary, swift check for drugs of abuse. This cost-efficient method is effective for ruling out drug use in most samples, but any positive screening result must be validated for court acceptance. Samples that test presumptive positive in Screening require further confirmation.
If a sample tests presumptive positive during the Screening phase, additional hair is extracted from the initial specimen for the Extraction process. Here, drugs are extracted from hair at notably lower concentrations compared to other methods (such as urine or oral fluid), underscoring the complexity of hair drug screening.
Positive screening confirmations are performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are properly cleansed before confirmation as necessary. The entire laboratory workflow, from Accessioning to Confirmation, is overseen under CAP (College of American Pathologists) Hair designation and adheres to ISO/IEC 17025 standards.
