Hair testing has been acknowledged as a vital mechanism for detecting drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug usage by capturing biomarkers within the fibers of the advancing hair shaft. When gathered near the scalp, hair can reveal up to around a 3-month window for detecting alcohol and drugs. Hair is straightforward to collect, relatively hard to tamper with, and effortless to transport.
A 1.5-inch sample comprising roughly 200 hair strands (akin to the thickness of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the optimal sample for testing and confirmation. For EtG, additional tests, and/or assessments beyond 10 panels, a 150mg specimen is advisable. It's suggested to weigh the specimen using a jeweler’s scale. If scalp hair is unavailable, a corresponding amount of body hair may be collected. When discussing head hair, we are referring solely to scalp hair. Body hair pertains to all other hair varieties (facial, axillary, etc.).
Process Overview
The four fundamental stages in processing a drug test result within the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into the laboratory's system. It involves ensuring the sample was sealed and dispatched properly, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data entry not incorporated through an electronic chain of custody system.
Screening pertains to an initial rapid analysis for drug abuse. While Screening is an economical method to exclude drug usage on most samples, a positive screen must be confirmed for court admissibility. Any samples that are tentatively positive in Screening indeed need further confirmation.
If a sample is tentatively positive during the Screening phase, more hair is extracted from the original specimen and prepared for Extraction. During this stage, drugs are extracted from hair at significantly lower concentrations than in other methodologies (e.g., urine or oral fluid), highlighting why hair drug screening is among the most challenging methodologies to execute.
Confirmation of any positive screening outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All tentatively positive samples are cleansed before confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
