Hair testing has emerged as an influential method for detecting drug and alcohol presence. Hair retains a lengthy historical record of alcohol and drug usage by embedding biomarkers in its fibers as it grows. When cut close to the scalp, hair can reveal up to a three-month period of substance use. Hair collection is straightforward, not easily tampered with, and simple to transport.
A 1.5-inch section of around 200 hairs (roughly the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for both screening and confirmation. For EtG, supplementary tests, and/or tests exceeding 10 panels, a sample size of 150mg is advised. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair is absent, an equivalent volume of body hair can be used. References to head hair specifically denote scalp hair, while body hair refers to all other hair types (facial, axillary, etc.).
Process Overview
The four primary phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the lab's system. This phase includes verifying proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any additional data entry absent from the electronic chain of custody.
Screening entails an initial rapid test for drugs of misuse. Although Screening is an economical method to eliminate drug presence in most samples, its positive results need confirmation to hold up in legal situations. Any samples that test presumptive positive in Screening necessitate further confirmation.
If a sample yields a presumed positive result in the Screening phase, additional hair from the original sample is utilized for Extraction. Here, drugs are extracted at concentrations much lower than those in other test forms (e.g., urine or oral fluid), resulting in hair drug testing being the most complex to conduct.
Confirmation for any presumptive positive result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All such samples go through a cleaning process before confirmation when required. The complete lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
