Hair testing has emerged as a formidable means for identifying the use of drugs and alcohol. Hair serves as a lengthy record of alcohol and other drugs by embedding biomarkers within the growing hair strand's fibers. When gathered near the scalp, hair can indicate drug and alcohol use for an estimated period of 3 months. Hair is easy to gather, relatively tough to tamper with, and simple to transport.
A 1.5-inch sample comprising roughly 200 hair strands (approximately the size of a #2 pencil) closest to the scalp yields about 100mg of hair, which is the preferred sample size for screening and confirmation purposes. For tests like EtG, add-ons, and/or those exceeding 10 panels, 150mg of the sample is suggested. Using a jeweler’s scale to weigh the specimen is advised. Should scalp hair be unavailable, a similar quantity of body hair can be collected. The term head hair refers strictly to scalp hair. Conversely, body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The four key steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a specimen into a lab’s system. This step ensures the sample was sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry absent from an electronic chain of custody system.
Screening entails an initial rapid assessment for substance abuse. Screening provides a cost-efficient approach to exclude drug use in the bulk of samples, though a positive screen necessitates confirmation for courtroom admissibility. Any sample testing presumptively positive in Screening mandates a secondary confirmation.
Should a sample test presumptively positive during Screening, additional hair is extracted from the primary specimen and prepared for Extraction. During this phase, hair reveals drugs at much finer levels compared to other methods (e.g., urine or oral fluid), rendering hair drug testing as the most challenging methodology to execute.
Confirmation of any positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive are washed before confirmation, if required. The complete lab procedure from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair classification and accreditation according to ISO / IEC 17025 standards.
