Hair testing has become regarded as an effective means for identifying drug and alcohol consumption. Hair captures a comprehensive history of alcohol and drug use by securing biomarkers within the strands. When clipped close to the scalp, hair can offer a detection period of up to roughly three months for both alcohol and drugs. Hair is easy to collect, relatively challenging to tamper with, and straightforward to transport.
A 1.5-inch segment comprising approximately 200 hair strands, similar in size to a #2 pencil, nearest to the scalp provides a 100mg sample, which is optimal for screening and confirmation processes. For EtG analyses, additions, or tests beyond 10 panels, a 150mg sample is advised. Utilizing a jeweler's scale, we recommend measuring the sample. Should scalp hair be absent, an equivalent volume of body hair can serve as a substitute. When referring to head hair, it specifically pertains to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the sample's initial entry into a laboratory's system. This stage verifies that the sample was appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry absent from an electronic chain of custody system.
Screening provides an initial, swift assessment for substances of abuse. Although Screening is a cost-efficient approach to exclude drug use in most samples, a positive result must be substantiated to be admissible in legal proceedings. Samples with presumptive positive results from Screening necessitate further confirmation.
Should a sample yield a presumptive positive during Screening, more hair is extracted from the primary specimen and prepped for Extraction. Here, drugs are isolated at significantly lower concentrations than in other methods (e.g., urine or oral fluid), rendering hair drug screening as one of the most challenging methodologies to conduct.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a wash before confirmation if necessary. The comprehensive laboratory process, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
