Hair examinations have become perceived as an efficacious means for detecting alcohol and drug consumption. Hair retains an extended timeline of drug and alcohol usage by embedding biomarkers within the threads of the developing hair shaft. When acquired near the scalp, hair offers an approximately 3-months timeframe for drug and alcohol detection. Hair is straightforward to gather, relatively resistant to tampering, and convenient to transport.
A segment measuring 1.5 inches, consisting of around 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp, will yield 100mg of hair, constituting the optimum specimen for both screening and validation processes. For EtG, additional tests, and/or assessments exceeding 10 panels, 150mg of the sample is advised. We suggest utilizing a jeweler's scale for specimen weighing. In the absence of scalp hair, a similar quantity of body hair might be acquired. When discussing head hair, we exclusively refer to scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).
Process Overview
There are four primary steps entailed in the lab handling of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into a lab's platform. This step confirms that the sample was appropriately sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and finalizes any residual data input not supplied by a digital chain of custody procedure.
Screening comprises an initial rapid assessment for substance misuse. Although Screening is a cost-efficient technique to exclude drug usage in most samples, any positive screening requires validation to be legally accepted. Samples showing a presumptive positive in Screening necessitate a secondary validation.
If a sample shows presumptive positivity in the Screening step, additional hair is extracted from the initial sample, readying it for Extraction. At this juncture, substances are extracted from hair at substantially lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging procedure to execute.
Validation of any positive screening finds its foundation in GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before validation as dictated by necessity. The comprehensive lab procedure from Accessioning to Validation is examined under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 guidelines.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed as "hair follicle tests," the analysis is conducted on the hair shaft, not the follicle beneath the scalp.
