Hair testing has become a recognized method for identifying drug and alcohol consumption. It captures long-term evidence of substances by embedding biomarkers within the structure of hair strands as they grow. When hair is acquired close to the scalp, it can reveal alcohol and drug presence for up to about 3 months. The process of collecting hair is straightforward, fairly resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches with roughly 200 hair strands (equivalent to a #2 pencil) near the scalp provides 100mg, which is the optimal amount for examination and confirmation. For EtG, supplements, and/or tests exceeding 10 panels, 150mg is advised. Utilizing a jeweler’s scale to measure the sample is recommended. If scalp hair isn't available, an equivalent quantity of body hair can be used. When the term head hair is utilized, it specifically refers to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The drug test result processing in the lab involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of entering a sample into a laboratory’s system, ensuring that the sample is properly sealed and shipped, assigning it a unique LAN (Laboratory Accessioning Number), and completing any additional information not provided by an electronic chain of custody system.
In the Screening phase, an initial rapid check for drug abuse is conducted. While this approach is cost-effective for dismissing drug use in most samples, a positive screen must be verified to be valid in court. Samples that are tentatively positive in Screening require further confirmation.
Should a sample test tentatively positive in the Screening step, additional hair is extracted from the initial collection and prepared for Extraction. This process involves extracting drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies to execute.
Verification of any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS technology. All samples preliminarily positive are washed before confirmation as required. The comprehensive laboratory process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and accredited to ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the analysis involves examining the hair strand and not the hair follicle beneath the scalp.
