Hair testing is now considered an effective method to detect drug and alcohol consumption. Hair captures a detailed history of drug and alcohol use by holding biomarkers within the growing hair strand. When taken near the scalp, hair can reveal usage of alcohol and other substances over a period of about 3 months. Collecting hair is straightforward, fairly resilient to tampering, and convenient to transport.
A 1.5-inch sample containing around 200 hair strands, approximately the width of a #2 pencil, closest to the scalp should yield 100mg of hair, which is optimal for testing and verification. For EtG, additional tests, and tests exceeding 10 panels, a sample of 150mg is preferable. It's advisable to measure the sample using a jeweler’s scale. If scalp hair isn't accessible, a similar volume of body hair can be collected. Head hair strictly refers to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The key stages in processing a drug test result in a lab include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed within the lab's system. This entails checking that the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data input not provided by an electronic chain of custody system.
Screening conducts a preliminary investigation for drugs of abuse. While Screening is a cost-efficient method to discard potential drug presence for most samples, a positive Screening result must be verified to hold in a legal context. Any samples initially positive in Screening require confirmed verification.
Should a sample test positive in Screening, additional hair is extracted from the original sample and prepared for Extraction. Drugs are extracted in this phase at very low concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most challenging methodology to execute.
Verification of any positive Screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as required. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation requirements.
