Hair testing is recognized as an effective method for detecting alcohol and drug use. The structure of hair strands captures biomarkers, providing a historical record of substance use. When hair is taken near the scalp, it offers approximately a three-month detection window for substances. The process of collecting hair is straightforward, relatively resistant to tampering, and convenient for transportation.
A sample measuring 1.5 inches, consisting of around 200 hair strands (comparable to the thickness of a #2 pencil), yields 100mg of hair, which is the optimal quantity for preliminary and confirmatory testing. For EtG, additional analyses, or tests exceeding 10 panels, a specimen weighing 150mg is advised. Utilizing a jeweler's scale for weighing the sample is recommended. In cases where scalp hair is unavailable, a comparable amount of body hair can be used. References to head hair strictly mean scalp hair, while body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initiating the sample processing within a lab’s framework. This process includes verifying the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not handled by an electronic chain of custody system.
Screening is a preliminary, rapid assessment for potential drug use. While Screening is an economical approach to eliminate drug usage in most samples, a positive screen must be validated to be accepted in legal settings. Any samples with a presumptive positive in Screening necessitate further confirmation.
If Screening indicates a presumptive positive, additional hair is extracted from the initial sample and prepared for Extraction. This phase involves extracting drugs from hair at concentrations significantly lower than other methods (such as urine or oral fluid), making hair drug screening particularly challenging.
Confirmation of any positive result from the screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positivity are washed before confirmation if required. The complete lab process, from Accessioning to Confirmation, is subject to review under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.
