Hair analysis is renowned for its effectiveness in uncovering drug and alcohol consumption. It offers an extended timeline of substance use by preserving biomarkers within the fibers of the hair strand as it grows. When sampled from near the scalp, hair can reveal up to around a 90-day timeframe for the presence of alcohol and drugs. Collecting hair is straightforward, less susceptible to tampering, and easy to transport.
A 1.5-inch portion of approximately 200 hair strands (akin to the thickness of a #2 pencil) closest to the scalp can provide 100mg of hair, which is optimal for screening and validation. For EtG extensions and/or panels beyond 10, a recommended 150mg of the sample should be used. We suggest measuring the sample with a jeweler’s scale. If scalp hair isn’t available, an equivalent quantity of body hair can be taken. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other forms such as facial and underarm hair.
Process Outline
The laboratory procedure for processing drug test results comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample is incorporated into the laboratory’s system. This step ensures that the sample was sealed and shipped correctly, assigns an arbitrary LAN (Laboratory Accessioning Number), and includes any additional data entry required beyond what an electronic chain of custody system provides.
Screening conducts an initial, rapid evaluation for drug abuse. As a cost-efficient approach, Screening can rule out drug usage for most samples, though any positive findings need confirmation to hold in court. Presumptive positive results from Screening necessitate further validation.
In cases of presumptive positive results in the Screening phase, additional hair is extracted from the original sample for the Extraction process. Here, hair releases drugs at noticeably lower concentrations compared to other methods (e.g., urine or oral fluids), making hair drug testing particularly challenging.
GC/MS, GC/MS/MS, or LC/MS/MS methods are employed to confirm any positive screenings. All samples showing presumptive positives are washed prior to confirmation if necessary. The comprehensive lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair requirements and ISO / IEC 17025 accreditation standards.
