The use of hair testing has emerged as a significant method for detecting substance and alcohol consumption. Hair retains a long-term record of alcohol and other substances by embedding biomarkers in the strands as they grow. When sourced near the scalp, hair can offer a detection span for alcohol and other drugs of up to roughly three months. The collection of hair is straightforward, not easily tampered with, and convenient for shipment.
A sample of approximately 1.5 inches comprising about 200 hair strands (comparable to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect amount for screening and verification. For tests involving EtG, additional components, and/or panels beyond 10, a sample of 150mg is advised. It's suggested to weigh the sample on a jeweler’s scale. Should scalp hair be unavailable, an equal volume of body hair can be used. Reference to head hair pertains solely to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. This step includes confirming that the sample was properly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and finalizing any further data entry not facilitated by an electronic chain of custody system.
Screening consists of an initial, rapid assessment for substance abuse. Although Screening provides a cost-efficient means to eliminate drug use for most samples, a positive screen still requires confirmation for legal admissibility. All samples that show positive indications during Screening must undergo secondary confirmation.
Samples that test presumptively positive during the Screening phase require additional hair from the original specimen for Extraction preparation. This stage involves extracting drugs from hair at concentrations much lower than other methods (e.g., urine or oral fluid), explaining why hair drug screening is among the most challenging techniques.
Confirming any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation if necessary. The full laboratory workflow from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair guideline and accreditation to ISO / IEC 17025 principles.
