Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. By encasing biomarkers within the strands of developing hair, it offers a comprehensive timeline of substance use. If gathered near the scalp, hair can reveal substance consumption within a detection window of up to roughly three months. The collection of hair is straightforward, tough to tamper with, and simple to transport.
A 1.5-inch portion consisting of about 200 strands of hair (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal specimen for preliminary and confirmatory testing. For EtG, add-ons, and tests exceeding 10 panels, a recommendation is 150mg of the sample. It's advisable to use a jeweler’s scale for weighing the specimen. If scalp hair is not present, equivalent amounts of body hair may be used. The term head hair specifically denotes scalp hair, while body hair refers to all other types like facial, axillary, etc.
Process Overview
The laboratory assessment of a drug test outcome encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the preliminary incorporation of a specimen into a lab's workflow. It entails verifying proper sealing and shipment of the sample, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any extra data input absent from an electronic custody system.
Screening serves as an initial rapid evaluation for substance abuse. While Screening offers a budget-friendly way to exclude substance consumption on most specimens, a positive screen must be validated to be court-eligible. Any specimens that are presumptively positive in Screening necessitate further confirmation.
For any specimen presumed positive during Screening, additional hair is extracted from the original sample and readied for Extraction. Here, drugs are isolated from hair at markedly lower levels than other methodologies, such as urine or oral fluid, making hair drug screening among the most challenging methods to execute.
Verification of any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo cleansing if necessary before confirmation. The comprehensive lab process from Accessioning to Confirmation is scrutinized in compliance with CAP (College of American Pathologists) Hair standards as well as ISO / IEC 17025 accreditation.
