Hair analysis is now widely recognized as an effective means of identifying drug and alcohol use. The hair strands keep a prolonged history of substance intake, capturing chemical indicators within the developing fiber. When collected near the scalp, it can offer a detection timeline of up to three months for both alcohol and drugs. It's easy to gather, tough to tamper with, and hassle-free to transport.
A sample approximately 1.5 inches long of around 200 hair strands (roughly the thickness of a #2 pencil) near the scalp will provide 100mg of hair, which is the optimal amount for testing. For tests like EtG or those exceeding ten panels, a 150mg sample is advised. Utilizing a jeweler's scale for measuring the specimen is recommended. If scalp hair isn't accessible, a comparable amount of body hair can be used. Head hair specifically denotes scalp hair, whereas body hair encompasses other types (like facial, axillary, etc.).
Process Overview
The primary steps in processing drug test results in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of feeding a sample into the lab's database. This procedure ensures that the sample is sealed and sent correctly, assigns it a random LAN (Laboratory Accessioning Number), and completes any required data entries not covered by an electronic chain of custody system.
Screening is a preliminary and fast check for substances commonly abused. As a cost-efficient measure, it rules out drug use in most samples; however, a positive result requires confirmation to be valid in legal scenarios. Every sample suspected of being positive post-Screening requires further verification.
For samples indicated as positive in Screening, additional hair is retrieved from the originally provided sample and prepared for Extraction. This phase extracts drugs from hair at minimal concentration levels compared to other methods (like urine or saliva), which is why hair analysis for drugs is considered particularly challenging.
Verification of any positive result from screening is done through GC/MS, GC/MS/MS, or LC/MS/MS. Any sample marked as presumptive positive undergoes a cleaning process prior to confirmation if necessary. The whole laboratory sequence from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and accreditation to ISO / IEC 17025 regulations.
