Hair testing has increasingly become recognized as a potent method for identifying drug and alcohol consumption. Hair captures a comprehensive historical record of substance use by encapsulating biomarkers within the fibers of the growing strand. Obtaining samples near the scalp can reveal substance history extending to roughly a 3-month period. The collection of hair samples is straightforward, challenging to tamper with, and convenient for shipping.
A sample measuring 1.5 inches with approximately 200 hair strands (comparable to a #2 pencil size) cut nearest the scalp provides 100mg, the optimal amount for examination and validation. For testing beyond 10 panels or including EtG tests, a specimen of 150mg is advisable. Using a jeweler’s scale to measure the specimen weight is suggested. Should scalp hair be inaccessible, you can collect an equivalent mass of body hair. References to head hair specifically mean scalp hair, while body hair encompasses other types (such as facial or axillary).
Process Overview
There are four principal steps in the lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the primary procedure for inputting a specimen into the laboratory’s system. This step ensures the sample is sealed and transported appropriately, assigns a random LAN (Laboratory Accessioning Number), and completes leftover data entry absent in an electronic chain of custody system.
Screening is a preliminary assessment for detecting drug abuse. Though cost-efficient for excluding drug use in most cases, a positive screening necessitates confirmation to be legal in judicial settings. Presumptive positive samples in Screening require an auxiliary confirmation.
For samples deemed presumptively positive in Screening, additional hair from the original specimen is set aside for Extraction. Drugs in this stage are retrieved from hair at smaller concentrations than with alternative methods (e.g., urine or oral fluid), which underscores the complexity of hair drug testing.
Confirmation of any positive screening result relies on GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Before confirmation, presumptive positive samples undergo washing as required. The whole procedure from Accessioning to Confirmation is reviewed and accredited under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 criteria.
