Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. Hair offers an extended record of alcohol and drug intake by capturing biomarkers within the fibers of the hair as it grows. When gathered near the scalp, hair can reveal substance use for a period of up to around three months. Hair collection is straightforward, tough to tamper with, and easy to transport.
Collecting a 1.5-inch segment of roughly 200 hair strands (approximately the thickness of a standard pencil) nearest to the scalp yields 100mg of hair, which is the preferred sample quantity for evaluations and confirmations. For EtG tests, additional tests, or those exceeding 10 panels, 150mg of the sample is advised. It's suggested to weigh the sample with a precision jeweler’s scale. If scalp hair cannot be obtained, an equivalent quantity of body hair can be used. When discussing head hair, we refer solely to scalp hair. Body hair encompasses all other types (e.g., facial, underarm hair).
Process Overview
There are four primary stages in processing a drug test in the lab: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of the sample into the lab’s system. This stage ensures the sample was secured and transported properly, assigns a unique LAN (Laboratory Accessioning Number), and handles any supplementary data entry not managed by an electronic chain of custody platform.
The Screening phase entails an initial rapid test for substance abuse. While Screening serves as a cost-effective method to exclude drug use for most samples, a positive outcome necessitates confirmation for legal admissibility. Samples initially testing positive in Screening mandate further confirmation.
Should a sample test positive during the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. At this stage, drugs are separated from the hair at concentrations lower than those in other testing methods (such as urine or oral fluid), rendering hair drug testing the most challenging method to execute.
Confirmation of a positive screen outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All initial positive samples are cleaned before confirmation if required. The comprehensive lab process from Accessioning to Confirmation is conducted under the CAP (College of American Pathologists) Hair directive alongside accreditation to ISO / IEC 17025 benchmarks.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed "hair follicle tests", the analysis focuses on the hair strand itself, not the follicle beneath the scalp.
