Seen as an effective means for discovering drug and alcohol usage, hair testing utilizes the hair fibers to capture biomarkers, rendering a historical record of consumption. With strands collected near the scalp, the test can detect substances within a roughly 3-month period. The simplicity of hair collection, coupled with its resistance to tampering and ease of shipment, renders it effective.
An ideal sample comprises a 1.5-inch segment of approximately 200 hair strands, equating to the thickness of a #2 pencil, yielding 100mg ideal for screening and confirmation. For testing involving EtG, add-ons, or panels exceeding 10, a 150mg sample is advisable. It is suggested that specimens be weighed using a jeweler’s scale. In the absence of scalp hair, an equal measure of body hair may be substituted. References to head hair pertain solely to scalp hair, while body hair encompasses all other varieties (such as facial and axillary hair).
Process Overview
The laboratory processing of a drug test result involves four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes integrating the sample into the lab system, confirming proper sealing and shipping, generating a unique LAN (Laboratory Accessioning Number), and completing any additional manual data entry not covered by an electronic chain of custody.
Screening provides an initial examination for substances. While cost-effective for ruling out drug use across most samples, a positive test requires confirmation for court admissibility. Presumptively positive samples from Screening need secondary validation.
Should Screening indicate a presumptive positive result, additional hair from the initial sample is prepared for Extraction. This phase isolates drugs from hair at concentrations significantly lower than those in alternative methods like urine or oral fluid, contributing to the complexity of hair drug screening.
Confirmation for any positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a cleansing process before Confirmation as deemed necessary. The complete procedure from Accessioning through Confirmation aligns with CAP (College of American Pathologists) Hair criteria and complies with ISO / IEC 17025 standards.
