Hair analysis has gained recognition as a robust method for detecting substance use and alcohol consumption. Hair captures a long-term record of alcohol and substance markers by embedding these biomarkers within the fibers of the growing hair strand. When collected from near the scalp, hair can offer a detection window of up to around three months for both alcohol and drugs. Hair sample collection is straightforward, relatively resistant to tampering, and convenient to ship.
By acquiring a 1.5-inch sample comprising about 200 hair strands (approximately the diameter of a #2 pencil) from the scalp, one can obtain 100 mg of hair—the optimal amount for both screening and verification. For EtG tests, supplementary tests, and/or screenings beyond 10 panels, it is suggested to collect 150 mg of the specimen. Utilizing a jeweler’s scale for weighing the specimen is advised. In cases where scalp hair isn't obtainable, an equivalent quantity of body hair can be used. References to head hair pertain exclusively to scalp hair, whereas body hair encompasses all other forms (such as facial, axillary, etc.).
Process Overview
The four primary stages involved in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of inputting a sample into a lab’s system. This step ensures the sample was properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any additional data entry absent from an electronic chain of custody system.
Screening is an initial swift evaluation for the presence of substances of abuse. Although Screening offers a cost-effective means to exclude drug usage in most samples, a positive result from this step must be confirmed to be legally admissible. Any samples inferred positive in Screening require secondary authentication.
When a sample shows a presumptive positive during the Screening process, additional hair is drawn from the initial sample for Extraction. This phase involves extracting drugs from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most intricate method to conduct.
Confirmation of positive Screening results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples presumed positive are cleansed before Confirmation when necessary. The full laboratory procedure, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.
