Hair analysis is now regarded as a robust method for identifying drug and alcohol usage. Hair encapsulates a prolonged history of substance consumption by preserving biomarkers within the fibers of the growing hair shaft. When collected near the scalp, it can offer up to a 90-day detection span for substances. The collection process is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch section of around 200 hair strands (approximately the width of a #2 pencil) closest to the scalp equates to roughly 100mg, which is the optimal sample size for both screening and confirmatory testing. For EtG, additional components, and/or examinations exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for accurate measurement. If scalp hair is not accessible, an equivalent portion of body hair can be used. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The drug test lab processing involves four central stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the beginning of incorporating a sample into a laboratory system. This step confirms whether the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finalizes any pending data entry absent from an electronic chain of custody system.
Screening is a preliminary and swift assessment for substances of abuse. Although Screening is an economical approach to disregard drug usage in most samples, a positive finding must be confirmed to be legally admissible. Any samples that preliminarily test positive during screening require a follow-up confirmation.
For samples preliminarily positive in the Screening segment, extra hair is extracted from the initial sample and readied for the Extraction stage. Here, drugs are retrieved from hair at significantly reduced concentrations compared to other methods (such as urine or oral fluid), making hair drug screening one of the most challenging methodologies.
Verification of any positive screening result is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if necessary. The entire lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
