Hair analysis is now regarded as a robust means for detecting substance use, both drug and alcohol. Hair captures long-term substance history by embedding biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can yield a detection timeframe of around 3 months for substances. It's straightforward to collect, moderately challenging to tamper with, and simple to transport.
A hair sample measuring 1.5 inches and consisting of approximately 200 strands (around the size of a #2 pencil) taken nearest to the scalp will provide 100mg, the optimal quantity for both screening and confirmation. For EtG, add-ons, and/or analyses exceeding 10 panels, 150mg of the sample is suggested. Using a jeweler’s scale is recommended to assess the specimen's weight. Should scalp hair be absent, an equivalent quantity of body hair can be utilized. Head hair refers exclusively to scalp hair, while body hair encompasses all other hair varieties (e.g., facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test outcome encompasses Accessioning, Screening, Extraction, and Confirmation.
The initial phase, Accessioning, involves entering a sample into a lab’s system. This step checks that the sample's seal and shipment were intact, assigns a random LAN (Laboratory Accessioning Number), and completes any further data entry beyond what an electronic chain of custody offers.
Screening offers a preliminary quick assessment for drugs of abuse. While it's a cost-efficient approach to exclude drug use in most samples, a positive screen must undergo confirmation to be valid in legal contexts. Any samples presumed positive during Screening require additional confirmation.
Should a sample be deemed presumptively positive in Screening, further hair is extracted from the initial sample for Preparation in the Extraction stage. In this phase, drugs are isolated from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which makes hair drug testing the most intricate method to conduct.
Confirmation of any positive screening findings is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation when necessary. The whole laboratory workflow from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 standards accreditation.
