Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended history of substance use by capturing biomarkers within the fibers of the growing hair shaft. When taken near the scalp, hair can offer up to a roughly 90-day detection timeline for alcohol and other drugs. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.
A 1.5-inch portion of approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for both initial screening and confirmation. For EtG, additional substances, and/or panels exceeding 10, a 150mg sample is suggested. It is advisable to measure the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent amount of body hair may be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair includes all additional hair types (facial, axillary, etc.).
Process Overview
The four fundamental stages in the laboratory handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into a lab’s system. This step involves checking that the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not supplied via an electronic chain of custody system.
Screening involves an initial rapid examination for substances of abuse. Although Screening is a cost-efficient method to exclude drug use in most samples, a positive screen must be verified to be admissible in legal proceedings. Any samples that test presumptively positive during Screening need a secondary confirmation.
Should a sample test presumptively positive at the Screening phase, additional hair is taken from the original sample and readied for Extraction. In this stage, substances are extracted from hair at significantly lower concentrations than in alternative methodologies (e.g., urine or oral fluid), contributing to hair drug testing being one of the most challenging methodologies to execute.
Validated confirmation of any positive screen result is performed through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.
