Analyzing hair has emerged as an effective method for identifying drug and alcohol consumption. Hair holds a long-term record of alcohol and drug intake by embedding biomarkers within the growing hair strand's fibers. When hair is collected close to the head, it can offer an approximate 3-month detection timeframe for alcohol and drugs. Hair is easy to gather, challenging to tamper with, and straightforward to transport.
A sample measuring 1.5 inches and comprising about 200 hair strands (comparable to the thickness of a #2 pencil) from near the scalp yields 100mg of hair, the ideal quantity for screening and confirming. For EtG, additional analyses, and/or tests over 10 panels, a 150mg specimen is advised. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair isn't an option, a similar quantity of body hair may be taken. The term head hair specifically refers to scalp hair. Body hair encompasses all other types, such as facial and axillary hair.
Process Overview
The laboratory process of determining a drug test result consists of four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial entry of a sample into a lab's system, involving the confirmation that the sample was correctly sealed and dispatched, the allocation of a random LAN (Laboratory Accessioning Number), and the completion of any additional data input absent from an electronic chain of custody system.
Screening represents an initial swift assessment for substances of abuse. Despite being a cost-efficient method to eliminate drug usage across most samples, a positive screen necessitates confirmation to be legally acceptable. Samples that preliminarily test positive in Screening must undergo secondary confirmation.
Should a sample show a presumptive positive in Screening, additional hair is extracted from the initial specimen for Extraction. Here, drugs are isolated from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), illustrating why hair drug testing is regarded as the most complex methodology to execute.
Verification of any positive screening outcome is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation as needed. The entire lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair category and the ISO/IEC 17025 certification standards.
