The testing of hair has emerged as a formidable approach for identifying drug and alcohol consumption. Hair serves as a chronicling medium of alcoholic and drug intake by embedding biomarkers within the fibers of the developing strand. Sampling from near the scalp, hair can reveal a detection window for substances approximately spanning up to 3 months. The collection of hair is straightforward, challenging to tamper with, and convenient to transport.
A hair sample of 1.5 inches, consisting of about 200 strands (comparable in size to a #2 pencil), from closest to the scalp yields 100mg, the optimal quantity for both screening and verification. For EtG, additional tests or those exceeding 10 panels, a 150mg sample is advised. We suggest utilizing a jeweler’s scale for specimen weighing. In the absence of scalp hair, an equivalent sample of body hair can be gathered. When discussing head hair, we exclusively refer to scalp hair. Body hair pertains to all other hair forms (facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase of integrating a sample into a lab’s system. This encompasses a review to ensure the sample was correctly sealed and dispatched, assignment of a randomized LAN (Laboratory Accessioning Number), and completion of other data entries not captured by an electronic custody tracking system.
The Screening phase is a preliminary and swift examination for drug presence. Although cost-effective for eliminating drug use on most samples, a positive Screening outcome necessitates confirmation to hold validity in court. All samples flagged with a preliminary positive in Screening require subsequent confirmation.
Should a sample indicate a presumptive positive in the Screening phase, extra hair is extracted and prepped for the Extraction phase. At this point, drugs are extracted from hair at notably lower concentrations than other methods (such as urine or oral fluid), which accounts for the complexity of hair drug screening.
GC/MS, GC/MS/MS, or LC/MS/MS technology is applied for confirming any positive Screening outcomes. All samples presumed positive undergo washing as required before confirmation. The complete lab procedure, from Accessioning through to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair stipulated guidelines and ISO / IEC 17025 accreditation standards.
