Hair analysis has emerged as a robust method for detecting drug and alcohol consumption. Hair retains a comprehensive record of alcohol and other substances by embedding biomarkers within the strands as it grows. When procured from near the scalp, it offers nearly a 3-month window for detecting alcohol and drug use. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
Acquiring a 1.5-inch sample of roughly 200 hair strands (around the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is ideal for initial and confirmatory assessments. For EtG, additional testing, and tests exceeding 10 panels, 150mg of hair is suggested. It’s advisable to measure the specimen with a jeweler’s scale. If scalp hair is not accessible, an equivalent quantity of body hair may be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses other hair types (facial, axillary, etc.).
Process Overview
The processing of drug test results in a lab involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage that incorporates a sample into a lab’s system. This phase ensures the sample was properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry absent in an electronic chain of custody.
Screening is a preliminary check for drug abuse. Although Screening is an economical method to dismiss drug use in most samples, a positive result demands confirmation to hold up in court. Presumptive positives from Screening mandate a follow-up confirmation.
If Screening indicates a presumptive positive, additional hair from the original sample is extracted for further processing. In this phase, drugs are drawn out from the hair at lower concentrations than other methods (e.g., urine or oral fluid), making hair drug analysis a particularly intricate technique.
Any positive Screening outcome undergoes Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples may be washed before Confirmation. The complete lab process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
