Hair analysis has emerged as a robust mechanism for identifying substance use. It offers a prolonged record of alcohol and drug consumption by capturing markers within the hair's fibers as they grow. By acquiring samples near the scalp, this method can reveal substance use within a window of up to roughly three months. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch sample of approximately 200 hair strands (comparable in thickness to a #2 pencil) nearest to the skin surface provides 100mg of hair, which is optimal for both preliminary and verified testing. When testing for EtG, additional panels, or beyond 10 panels, a 150mg sample is advised. Utilizing a jeweler's scale to weigh the sample is recommended. In cases where scalp hair is not available, an equivalent volume of body hair can be used. "Head hair" pertains only to scalp hair, while "body hair" includes all other hair types (such as facial and axillary hair).
Process Overview
The laboratory analysis of a drug test result is conducted through four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the preliminary processing of a sample within a lab system. This step ensures the sample was properly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and addresses any additional data entry not covered by an electronic custody chain.
Screening functions as an initial, rapid assessment for substances of abuse. Though cost-effective for ruling out drug use in most samples, any positive Screening outcome must be confirmed for court validity. Any samples preliminarily positive in Screening necessitate further confirmation.
If Screening suggests a presumptive positive, additional hair is extracted from the initial sample and readied for Extraction. During this phase, hair releases substances at much lower doses compared to other methods (e.g., urine or oral fluid), a factor contributing to the complexity of hair drug testing.
Confirmation of any positive screening result is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples are washed before confirmation as required. The complete laboratory process, from Accessioning to Confirmation, is reviewed per the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
