Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. The hair essentially captures a prolonged history of substances by preserving biomarkers within the fibers of the developing hair shaft. When obtained near the scalp, it can offer a detection period of nearly three months for both alcohol and drugs. Hair is straightforward to collect, relatively resistant to tampering, and convenient for dispatch.
A sample measuring 1.5 inches with roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for screening and validation. For EtG add-ons and/or tests exceeding 10 panels, a recommendation of 150mg of the sample is suggested. We advise using a jeweler's scale to weigh the specimen. Should scalp hair be unavailable, an equivalent quantity of body hair can be utilized. When referencing head hair, we mean scalp hair exclusively. Body hair encompasses all other types, such as facial or axillary.
Process Overview
The core procedures in the lab analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary processing of a sample into a lab's database. It ensures the sample was appropriately sealed and shipped, assigns a random Laboratory Accessioning Number (LAN), and inserts any supplementary information not included by an electronic chain of custody system.
Screening entails a quick preliminary check for drugs of abuse. Although Screening is a cost-efficient tactic for excluding drug use in most samples, any initial positive result must be validated to be court-acceptable. Samples that show a presumptive positive in Screening need a secondary validation.
If a sample reveals a presumptive positive during the Screening phase, additional hair is retrieved from the initial sample for Extraction. In this phase, drugs are extracted from hair at a notably lower concentration than in alternative methods (e.g., urine or oral fluid), contributing to hair drug screening being one of the most intricate methods to execute.
Confirmation for any initial positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and accreditation according to ISO/IEC 17025 standards.
