Hair analysis is gaining recognition as an effective means for identifying drug and alcohol consumption. Hair captures biomarkers within the fibers of the hair as it grows, offering a comprehensive history of drug and alcohol use. When taken near the scalp, hair can reveal substance use over a period of up to three months. Collecting hair is straightforward, and it is relatively resistant to tampering and easy to transport.
A sample measuring 1.5 inches in length and containing approximately 200 hair strands (comparable in diameter to a #2 pencil) can provide 100mg of hair, which is ideal for both screening and confirmation tests. For EtG, additional analyses, or tests exceeding ten panels, 150mg of hair is suggested. We advise weighing the hair sample using a jeweler's scale. If scalp hair is not available, a similar amount of body hair can be used. When discussing head hair, we specifically mean scalp hair, while body hair pertains to all other types such as facial and underarm hair.
Process Overview
Drug test results are processed through four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step where a sample is initially entered into a lab's records. This phase involves confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and filling in any missing data that is not provided by an electronic chain of custody.
Screening consists of a preliminary assessment to check for substance abuse. While Screening is a cost-efficient approach for ruling out drug use in most samples, any positive findings must be verified for legal admissibility. Samples showing presumptive positive results during Screening require further confirmation.
If the Screening stage yields a presumptive positive, additional hair is extracted from the initial specimen for the Extraction phase. During Extraction, drugs are recovered from hair at concentrations lower than those found in other forms like urine or saliva, highlighting the complexity of performing hair drug screening.
Positive Screening results are verified through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive findings undergo a washing process before confirmation, if necessary. From Accessioning through Confirmation, the entire laboratory process is evaluated under both CAP (College of American Pathologists) Hair criteria and conformance to ISO / IEC 17025 standards.
