Hair analysis has gained recognition as an effective means for detecting substance use, including drugs and alcohol. Hair locks in biomarkers within its fibers, offering an extended record of substance consumption. When taken near the scalp, hair can reveal usage within a 3-month timeframe. The process is easy to perform, tough to alter, and straightforward to transport.
A 1.5-inch segment of roughly 200 hair strands (equivalent to the dimensions of a #2 pencil) from near the scalp yields 100mg, ideal for initial testing and confirmation. For EtG evaluations or tests exceeding 10 panels, 150mg is preferred. Using a jeweler’s scale for precise measurement is suggested. In the absence of scalp hair, an equivalent quantity of body hair can be used. References to head hair specifically mean scalp hair, while body hair includes other types (e.g., facial, axillary).
Process Overview
The laboratory procedure for drug testing consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating the sample into the lab system, confirming the sample's proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data input not covered by an automated chain of custody.
Screening acts as an initial rapid assessment for drug presence. Though it’s a cost-efficient method to dismiss drug usage in most cases, any positive findings must be verified for legal admissibility. Presumptively positive samples from Screening need further confirmation.
For samples deemed positive in Screening, additional hair is extracted for the Extraction phase. Here, substances are removed from hair at lower concentrations than in other methods like urine or oral fluids, making hair drug analysis particularly challenging.
Confirmation for positive results uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positives are cleansed before confirmation. The full laboratory workflow, from Accessioning to Confirmation, aligns with CAP (College of American Pathologists) Hair guidelines and conforms to ISO / IEC 17025 standards.
