Hair testing is now acknowledged as an efficacious means to uncover drug and alcohol consumption. By capturing biomarkers within the fibers of the maturing hair strand, hair provides a prolonged timeline of substance intake. When gathered near the scalp, hair can offer up to roughly a three-month detection period for drugs and alcohol. It is straightforward to collect, somewhat challenging to tamper with, and convenient to dispatch.
A 1.5-inch section with around 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp will yield 100mg, which is the optimal sample for analysis and verification. For EtG, supplementary assessments, and/or analyses exceeding 10 panels, a 150mg sample is advisable. It's recommended to weigh the hair using a jeweler’s scale. Should scalp hair be inaccessible, a proportionate quantity of body hair may be obtained. The term head hair pertains solely to scalp hair, while body hair includes all other types (such as facial or axillary hair).
Process Overview
Four pivotal steps are undertaken in the lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the initial incorporation of a sample into a lab's system. This process involves affirming that the sample was correctly sealed and dispatched, assigning it a random LAN (Laboratory Accessioning Number), and filling in any missing data not included in an electronic chain of custody system.
. Screening conducts an initial rapid assessment for drugs of concern. Though Screening is economical for ruling out drug use in most samples, any positive screen demands further confirmation to hold up in court. Samples that yield a presumptive positive in Screening need secondary confirmation.
If Screening returns a presumptive positive result, additional hair is taken from the initial sample and prepped for Extraction, where drugs are extracted from hair at a much lower concentration compared to other methodologies (e.g., urine or oral fluid), making hair drug screening the most complex methodology to undertake.
Confirmation of any positive screen is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples require washing prior to confirmation if necessary. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
