Hair testing is now regarded as an effective resource for identifying alcohol and drug usage. It offers a prolonged record of drugs and alcohol as hair fibers trap biomarkers during growth. A sample collected near the scalp can reveal substance use over a span of up to 3 months. Hair collection is straightforward, resistant to tampering, and convenient for transportation.
Taking a 1.5-inch strand, approximately the volume of about 200 hairs (similar to a #2 pencil), near the scalp produces around 100mg, which is the optimal sample size for screening and analysis. For EtG, more detailed assessments, or when exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale to measure the specimen’s weight is suggested. If scalp hair is inaccessible, a comparable volume of body hair is acceptable. "Head hair" pertains to hair from the scalp only, while "body hair" refers to any other kind (like facial or axillary hair).
Process Overview
The laboratory stages for processing drug test outcomes consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails integrating the sample initially into the lab system. This step ensures the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry aside from the electronic chain of custody system.
The Screening phase offers an initial assessment for substance abuse. Although Screening is economically feasible for ruling out drug presence among most samples, a verified screening result is necessary for legal proceedings. Positive results in Screening must undergo confirmatory testing.
In cases of positive indications during Screening, additional hair is extracted from the sample and readied for Extraction. This stage involves extracting drugs from the hair at notably lower concentrations than other methods (such as urine or saliva), making hair analysis the most challenging technique.
Confirming a positive screening is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positives are cleansed as required. The complete lab process from Accessioning through Confirmation is audited under the CAP (College of American Pathologists) Hair designation and accredited by ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: This test, though often referred to as "hair follicle tests", actually examines the hair strand rather than the follicle beneath the scalp.
