The utilization of hair testing is recognized as an effective method for detecting the use of drugs and alcohol. Hair strands capture biomarkers within the fibers as they grow, offering a historical overview of alcohol and other drug usage over extended periods. A sample taken near the scalp can reveal drug and alcohol presence for a timeframe of up to roughly three months. The collection process for hair samples is straightforward, relatively resistant to tampering, and easy to transport.
Taking a sample measuring 1.5 inches from about 200 hair strands near the scalp, which corresponds to the size of a #2 pencil, results in a collection of 100mg of hair, an optimal amount for both screening and confirmation processes. For tests involving EtG, additional parameters, or those surpassing 10 panels, a specimen weight of 150mg is suggested. Utilizing a jeweler’s scale for measurement is advised. In situations where scalp hair is absent, the collection of an equivalent mass of body hair is permissible. The term "head hair" specifically pertains to scalp hair, whereas "body hair" encompasses all other types, including facial and axillary hair.
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample's initial processing within a laboratory's infrastructure, which includes tasks such as ensuring the sample's proper sealing and shipment procedures, assigning it a unique LAN (Laboratory Accessioning Number), and completing any further data entry not covered by an electronic chain of custody system.
Screening serves as an initial, rapid assessment for detecting drugs of abuse. Though Screening is a cost-efficient method to eliminate drug usage in most samples, any positive findings need confirmation for legal admissibility. Samples showing presumptive positive results in Screening must undergo a secondary confirmation.
During the Screening phase, if a sample tests presumptively positive, additional hair is taken from the original specimen and readied for Extraction. This stage involves extracting drugs from hair at significantly lower concentrations compared to other methods such as urine or oral fluid analysis, explaining why hair drug screening is considered the most challenging to administer.
The Confirmation phase for any positive screening result employs methodologies like GC/MS, GC/MS/MS, or LC/MS/MS. To ensure accuracy, all samples indicating presumptive positives are cleansed prior to confirmation if deemed necessary. The comprehensive laboratory process, extending from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair accreditation as well as ISO/IEC 17025 standards.
