Hair assays have gained recognition as an effective means for identifying substance use. Hair offers a lengthy retrospective history by immobilizing biomarkers within the fibers of its growing strands. When clipped near the scalp, hair can reveal drug and alcohol use over a span of about three months. Hair collection is straightforward, hard to tamper with, and convenient to transport.
A 1.5-inch segment comprising nearly 200 hair strands (similar to the thickness of a #2 pencil) near the scalp delivers 100mg of hair, the optimal amount for initial screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, it is advisable to use 150mg of the sample. Utilizing a jeweler's scale to measure the specimen is recommended. If scalp hair cannot be used, a comparable quantity of body hair is acceptable. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The principal phases in lab processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the sample's initial entry in the lab's system. It verifies the sample's seal and dispatch correctness, assigns a random LAN (Laboratory Accessioning Number), and concludes any residual data entry absent in an electronic chain of custody mechanism.
Screening functions as an initial, rapid assessment for substance misuse. Although Screening offers a budget-friendly method to exclude drug usage in most cases, positive screenings require confirmation to hold up in legal settings. Any samples showing a presumptive positive result need subsequent confirmation.
For samples indicating presumptive positivity in Screening, a portion of additional hair is extracted from the original specimen for the Extraction step. In this phase, drug components are drawn from hair at a notably lower density than other methods (e.g., urine or oral fluid), making hair drug testing amongst the most challenging methodologies to execute.
Any confirmed positive results undergo verification using GC/MS, GC/MS/MS, or LC/MS/MS. All samples suspected to be positive are cleansed before confirmation if necessary. The entire lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair specification and conforming to ISO / IEC 17025 criteria.
