Recognized as an effective means for detecting drug and alcohol consumption, hair analysis captures a long-term record of substance usage by securing biomarkers within the hair strand's evolving fibers. When obtained near the scalp, hair can reveal a detection range reaching up to roughly 3 months for alcohol and other substances. Collecting hair is straightforward, hard to tamper with, and simple to transport.
A sample size of 1.5-inch consisting of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for analysis and verification. For EtG, supplemental tests, and/or examinations exceeding 10 panels, 150mg of the sample is suggested. A jeweler’s scale is recommended for weighing the sample. If scalp hair isn’t accessible, an equivalent quantity of body hair may be collected. References to head hair pertain solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result is divided into four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning commences with the initial processing of a sample into a lab's system. This step entails ensuring that the sample was appropriately sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody framework.
Screening involves a preliminary assessment for drug abuse. Although Screening is an economical method for excluding drug usage in most samples, a positive finding needs to be verified to be legally valid. Any samples potentially positive in Screening mandate secondary confirmation.
In instances where a sample tests positive in the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are removed from hair at significantly lower concentrations than in other methodologies (such as urine or oral fluid), establishing hair drug testing as the most complex methodology.
Confirmation of positive screening outcomes is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples presumed positive undergo washing before confirmation as required. The end-to-end laboratory process, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair specification and the ISO / IEC 17025 accreditation standards.
