Hair analysis is now recognized as an effective method for detecting drug and alcohol consumption. The hair strand retains a historical record of alcohol and drugs by embedding biomarkers within its fibers as it grows. When gathered near the head, hair can reveal alcohol and drug use over an approximate 3-month span. Collecting hair is straightforward, hard to tamper with, and simple to transport.
A 1.5-inch section of around 200 hair strands (about the thickness of a #2 pencil) near the scalp can provide 100mg of hair, optimal for both screening and confirmation. For EtG, extra tests, and/or panels beyond 10, a 150mg sample is advised. We suggest measuring the sample with a jeweler's scale. Substitute hair from the body can be used if scalp hair is not available. When specifying head hair, it refers exclusively to scalp hair. All other types (facial, axillary, etc.) fall under body hair.
Process Overview
The drug test result processing in the laboratory involves four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes inputting a sample into a lab's system initially. This step checks if the sample was properly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and enters any further data not handled by an electronic chain of custody.
Screening provides a preliminary rapid assessment for substance abuse. Although it’s a cost-efficient method to eliminate drug use for most samples, a positive screening needs validation to be considered in legal settings. Presumptive positive samples in Screening require further confirmation.
If a Screening sample shows a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. Here, substances are removed from the hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluids), highlighting the complexity of performing hair drug screening.
Positive screenings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation, if necessary. The complete process, from Accessioning to Confirmation, undergoes review under the CAP (College of American Pathologists) Hair designation alongside ISO/IEC 17025 accreditation standards.
