Hair analysis has gained recognition as an effective tool to determine alcohol and drug consumption. This method captures biomarkers within the hair strand's fibers, offering an extended history of substance use. When samples are collected near the scalp, they can reveal alcohol and drug use across approximately a 90-day period. This method is straightforward for collection, relatively resistant to tampering, and convenient for shipping.
A proper sample involves a 1.5-inch section of around 200 hair strands (comparable to a #2 pencil) situated nearest to the scalp, yielding 100mg of hair, an optimal quantity for screening and verification. For EtG, additional tests, and analyses exceeding 10 panels, a 150mg sample is preferred. It's advisable to use a jeweler’s scale for weighing the sample. When scalp hair is not accessible, an equivalent quantity of body hair can be used. "Head hair" pertains solely to scalp hair, whereas "body hair" encompasses all other types, such as facial and axillary hair.
Process Overview
The process to evaluate a drug test sample in the lab encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Initial sample processing into a lab system is addressed through Accessioning. This step verifies if the sample was sealed and transported correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any other data entry omitted by an electronic chain of custody system.
Screening acts as a preliminary evaluation for drug presence. Though economical for ruling out drug use in most cases, a positive outcome from Screening necessitates subsequent verification for judicial acceptability. Samples showing preliminary positives in Screening must undergo Confirmation.
Upon a preliminary positive detected in Screening, further hair is taken from the original sample for Extraction. In this stage, drugs are withdrawn from hair at significantly lower concentrations than other methods, such as those involving urine or oral fluid, justifying the complexity of hair drug testing.
Confirmation for any Screening positives is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Preceding confirmation, presumptive positives are cleansed as necessary. The comprehensive process from Accessioning to Confirmation falls under the scrutiny of both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
