Hair testing is recognized as a robust tool in identifying drug and alcohol usage. Hair stores a long-term history of substances by embedding biomarkers within the growing fiber. When collected near the scalp, hair can offer roughly a 3-month detection period for alcohol and drugs. Collecting hair is straightforward, less prone to tampering, and easy to transport.
A 1.5-inch section of approximately 200 hair strands (comparable to the size of a #2 pencil) nearest the scalp will yield 100mg, an optimal sample for screening and confirmation purposes. For EtG, additional tests, and/or scenarios exceeding 10 panels, a 150mg specimen is advised. It's prudent to weigh the specimen using a jeweler’s scale. Should scalp hair be inaccessible, a comparable quantity of body hair may be acquired. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initiation of processing a sample into a lab’s system. This process checks that the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and handles any extra data entry absent from an electronic chain of custody system.
Screening is a preliminary test for illegal substances. Though cost-effective for excluding drug usage in most samples, a positive result in Screening must be confirmed for court admissibility. Samples showing a tentative positive in Screening require an additional confirmation.
For samples with a provisional positive in Screening, more hair is sourced from the original sample and readied for Extraction. In this phase, drugs are isolated from hair with a considerably lower concentration than other methods (e.g., urine or oral fluid), which makes hair drug screening a challenging methodology to execute.
Confirmation of any positive result from screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a provisional positive are washed before confirmation if necessary. The entire laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
