Hair testing is now recognized as a robust method for identifying drug and alcohol consumption. Hair captures a long-term record of substances by embedding biomarkers within the strands. When gathered near the scalp, hair can show substance usage for up to about three months. It is straightforward to collect, relatively hard to adulterate, and simple to transport.
A 1.5-inch segment of around 200 hair strands (about the width of a #2 pencil) nearest to the scalp yields 100mg, the optimal quantity for testing. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is suggested. It's advisable to measure the sample using a jeweler's scale. If scalp hair is unavailable, an equivalent amount of body hair can be used. Reference to head hair means scalp hair. Body hair includes all other hair forms (facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step where a sample enters a lab’s system. This step confirms proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any missing information not present in an electronic chain of custody system.
Screening performs an initial fast assessment for drugs. Although cost-efficient in ruling out drug use for most samples, a positive screen requires confirmation for legal admissibility. Any initial positive results in Screening need a follow-up confirmation.
If the Screening phase yields a presumptive positive, more hair is extracted from the original sample for Extraction. Here, drugs are removed from hair at a concentration substantially lower than other methods (like urine or oral fluid), marking hair drug screening as the most challenging methodology.
Confirmation of a positive screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as required. The entire process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
