Hair sampling has emerged as an impactful method to detect substance use. By capturing biomarkers within the strand's fibers, hair offers an extended historical record of drug and alcohol consumption. When taken near the scalp, hair provides a detection period of up to roughly three months for alcohol and drugs. Collection is straightforward, tampering is challenging, and shipping is convenient.
A 1.5-inch snippet of around 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg, the optimal amount for screening and confirmation. For EtG, additional panels beyond 10, 150mg of the sample is advised. Measuring the sample with a jeweler’s scale is suggested. If scalp hair isn’t available, an equivalent quantity of body hair can be gathered. Head hair indicates only scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test result involves four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first stage, processing a sample into the lab's system. This step verifies the proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any outstanding data entry if an electronic chain of custody system wasn't used.
Screening conducts an initial brief check for drug abuse. Though cost-efficient for excluding drug use in most cases, a positive result requires confirmation for court admissibility. Any samples that return a presumptive positive in Screening need further confirmation.
Should a sample show a presumptive positive at the Screening phase, additional hair is retrieved from the primary sample and prepared for Extraction. In this phase, drug concentrations are extracted from hair at levels much lower than other techniques like urine or oral fluid, underscoring why hair drug testing is particularly demanding.
Positive Screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation as necessary. The full laboratory procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
