Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair functions as a historical archive of substance intake by embedding biomarkers in the fibers of the growing strand. When taken close to the scalp, hair can offer a detection period of up to roughly 90 days for substances like alcohol and drugs. The collection process is straightforward, challenging to tamper with, and convenient for shipping.
A 1.5-inch segment of approximately 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for screening and validation. For tests such as EtG, extensions, and/or those exceeding 10 panels, a 150mg sample is advised. We suggest weighing the sample using a jeweler’s scale. If scalp hair cannot be procured, a similar quantity of body hair may be gathered. By “head hair,†we refer exclusively to scalp hair. “Body hair†encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of integrating a sample into a lab’s system. This step entails verifying the sample’s proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic chain of custody system.
Screening involves a preliminary examination for drugs of abuse. Although Screening serves as a cost-effective measure to exclude drug usage for most samples, a positive screen necessitates confirmation for legal admissibility. Samples that yield presumptive positives in Screening must undergo a secondary confirmation.
If a sample is indicative of positivity during Screening, additional hair is extracted from the original sample for Extraction. This phase involves retrieving drugs from hair at considerably lower concentrations than in other methodologies (e.g., urine or oral fluid), which renders hair drug screening as the most challenging methodology to execute.
Confirmation of any positive screening outcome is executed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation when necessary. The entire process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
