Hair analysis is increasingly recognized as an effective method for detecting the presence of drugs and alcohol. Hair offers a historical record of substance use by capturing biomarkers within the growing hair strand's fibers. When gathered close to the scalp, hair can reveal drug and alcohol consumption over a period of up to roughly three months. Collecting hair is straightforward, hard to tamper with, and convenient to transport.
A 1.5-inch segment containing about 200 hair strands (equivalent to a #2 pencil's thickness) near the scalp provides 100mg of hair, which is the optimal sample size for both screening and verification. For tests such as EtG, add-ons, or those exceeding 10 panels, a specimen of 150mg is advised. It's suggested to verify the specimen weight on a jeweler’s scale. In the absence of scalp hair, a similar volume of body hair may be taken. When mentioning head hair, it strictly refers to scalp hair, while body hair encompasses other types (beard, underarm, etc.).
Process Overview
There are four fundamental stages in the lab processing of a drug analysis result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample into a lab’s framework. This step includes ensuring the sample was correctly sealed and dispatched, creating a random LAN (Laboratory Accessioning Number), and filling in any supplementary data entry absent from an electronic chain of custody system.
Screening is a preliminary rapid assessment for substances of abuse. Although Screening is a cost-effective strategy to negate drug use for most samples, any screen that yields a positive result requires confirmation to be legally valid. Samples presumed positive during Screening necessitate secondary confirmation.
If a sample shows a presumptive positive at the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. At this juncture, drugs are retrieved from hair at significantly lower concentrations than through other methods (such as urine or oral fluid), rendering hair drug analysis the most intricate method to execute.
Any confirmed positive screening outcome is verified using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive are cleansed before confirmation, as required. The comprehensive lab process from Accessioning to Confirmation undergoes evaluation under the CAP (College of American Pathologists) Hair designation and the compliance with ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the test examines the hair strand itself rather than the follicle beneath the scalp.
