Hair testing has gained recognition as an effective means for detecting drug and alcohol consumption. Hair strands capture biomarkers within their fibers providing a prolonged history of substances consumed. When samples are collected near the scalp, they can supply detection for alcohol and other drugs for a timeframe of up to three months. Hair collecting is straightforward, not easy to manipulate, and simple to send.
A sample size of 1.5 inches comprising around 200 strands of hair (comparable to a #2 pencil) closest to the scalp provides a 100mg sample, ideal for initial and confirmatory tests. For analyses like EtG, additional panels, or those exceeding 10 panels, 150mg is advisable. It is suggested to measure the sample using a jeweler’s scale. If head hair is not accessible, the equivalent quantity of body hair may be collected. References to head hair imply solely scalp hair. Any other hair type such as facial or axillary hair is categorized as body hair.
Process Overview
The laboratory processing of drug tests includes four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step where a sample is processed into a lab’s system. This step ensures the sample is securely sealed and dispatched correctly, a random LAN (Laboratory Accessioning Number) is allocated, and any other necessary data entry not facilitated by an electronic chain of custody system is completed.
Screening serves as an initial, rapid check to identify drugs of abuse. Although Screening is a cost-efficient method to exclude drug use in most samples, a positive screen must be validated for court admissibility. Any samples indicative of positive results in Screening require subsequent confirmation.
When a sample shows presumptive positivity in Screening, additional hair is extracted from the preliminary sample and readied for Extraction. During this phase, drugs are extracted from hair at far lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging method to execute.
Confirmation for any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are washed prior to confirmation as necessary. The entire lab process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
