Hair tests have gained recognition as a robust method for identifying drug and alcohol consumption. Hair strands capture biomarkers in their fibers, delivering an extended overview of substance use. When obtained close to the scalp, hair can provide an approximate three-month detection range for alcohol and drugs. Collection is straightforward, with limited risk of tampering, and it's easy to transport.
For an optimal screening and confirmation test, a 1.5-inch segment containing roughly 200 strands (equivalent to a #2 pencil) nearest the scalp yields 100mg of hair, the preferred sample size. For EtG, add-ons, and tests exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale for measurement is suggested. In the absence of scalp hair, a similar quantity of body hair can be collected. The term head hair refers solely to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary processing of a specimen into the laboratory system. This step confirms that the sample was appropriately sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry absent from an electronic chain of custody system.
Screening provides an initial rapid assessment for drug abuse. While cost-efficient for ruling out drug use in most samples, Screening necessitates a secondary confirmation for any positive results to be valid in legal settings. Samples that indicate a presumptive positive in Screening require further confirmation.
For samples showing presumptive positives during the Screening phase, additional hair is retrieved from the initial sample and prepared for Extraction. Drugs are extracted from hair at lower concentrations than with other methods (e.g., urine or oral fluid), which accounts for the complexity of hair drug analysis.
Confirmation of positive screenings is performed through GC/MS, GC/MS/MS or LC/MS/MS. Before Confirmation, all presumptive positive samples undergo washing as needed. The comprehensive laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
