Hair analysis has emerged as a robust method for identifying drug or alcohol consumption. The hair captures extended histories of drug use by embedding biomarkers within the strands of hair as it grows. When hair is clipped near the scalp, it can offer a detection window of nearly three months for alcohol and other substances. Hair collects easily, is relatively tough to tamper with, and is convenient to transport.
Obtaining a 1.5-inch hair section consisting of around 200 strands (roughly the diameter of a #2 pencil) near the scalp yields 100mg of hair, which is perfect for initial screening and validation. For EtG, additional tests, and/or examinations beyond 10 panels, a 150mg sample is ideal. Using a jeweler’s scale is suggested for weighing the specimen. If scalp hair cannot be retrieved, an equivalent amount of body hair may be used. In discussions of head hair, we refer strictly to scalp hair, while body hair includes all other hair (facial, axillary, etc.).
Process Overview
The primary steps in the lab processing of a drug test outcome comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of processing a sample within a lab's system. This step entails confirming that the sample's sealing and dispatch were proper, assigning a unique LAN (Laboratory Accessioning Number), and completing any other necessary data entry not accounted for by an electronic chain of custody.
Screening is a preliminary assessment for potential drugs of abuse. Although Screening provides an economical means to dismiss drug usage in most samples, any positive results must undergo confirmation to be legally valid. Samples that yield a presumptive positive in Screening need further verification.
For samples that are suggested as positive during the Screening phase, more hair is drawn from the initial sample and readied for Extraction. Here, drugs are extracted from hair in much lower concentrations than other methods (such as urine or oral fluid), making hair drug screening the most challenging method to carry out.
Confirmation of any positive screen occurs through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples deemed presumptive positive are cleansed before confirmation if necessary. The complete lab procedure, from Accessioning to Confirmation, is conducted under both CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.
