Hair testing is now recognized as an effective method for identifying drug and alcohol usage. Hair offers an extensive timeline of substance intake by capturing biomarkers within the fibers of the growing strand. When taken near the scalp, hair can show drug or alcohol consumption for up to around three months. Collection is straightforward, tampering is tough, and shipping is easy.
A sample size of 1.5 inches with roughly 200 strands (similar to the thickness of a #2 pencil) nearest the scalp will produce 100mg of hair, which is the perfect specimen for both screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, it is suggested to gather 150mg. Use a jeweler’s scale for weighing the sample. If scalp hair is unobtainable, a matching amount of body hair can be used. 'Head hair' denotes only scalp hair. 'Body hair' includes all other types (facial, axillary, etc.).
Process Overview
The process of analyzing a drug test outcome in the lab involves these four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary intake of the sample into a lab's system. It confirms the correct sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and fills in any extra data not provided by an e-chain-of-custody system.
Screening provides a preliminary assessment for drug abuse. Though cost-efficient for excluding drug use in most samples, a positive screen must be verified for legal acceptance. Samples with a presumptively positive screen need secondary confirmation.
For samples presumed positive in Screening, additional hair is extracted from the initial sample and prepped for Extraction. This stage involves extracting drugs from hair at a much lower concentration than alternative methods (e.g., urine or oral fluid), rendering hair drug testing the most intricate methodology to execute.
Confirmation of any positive screen is done through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed before confirmation as needed. The full lab process from Accessioning to Confirmation is audited under CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.
