Hair analysis is increasingly considered a potent mechanism for identifying drug and alcohol consumption. The hair acts as a repository, retaining biological markers within its fibers as it grows, thus offering an extended historical view of substance use. When taken near the skin, hair can offer a revelatory span of up to three months for detecting alcohol and other substances. The collection of hair samples is straightforward, relatively tamper-resistant, and convenient for transport.
A specimen measuring 1.5 inches in length, consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) nearest the skin provides 100mg, an optimal amount for verification testing. For EtG supplements or assessments exceeding 10 panels, a specimen weighing about 150mg is advised. Utilizing a jeweler’s scale for weighing is suggested. Should scalp hair be inaccessible, an equivalent quantity of body hair is permissible for collection. The reference to head hair is specific to the scalp region. In contrast, body hair encompasses all other types, such as facial or axillary hair.
Process Overview
The crucial phases in the processing of a drug test outcome in a lab are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes introductory processing within a lab’s records. This ensures correct sealing and shipment, a Laboratory Accessioning Number (LAN) is generated at random, and any additional data entry that is absent from an electronic chain of custody system is finalized.
Screening initiates a preliminary and swift analysis for illicit substances. Although Screening offers a cost-efficient method to eliminate possible drug use for the majority of specimens, a positive indication requires further validation to be legitimately acceptable in legal circumstances. Any samples exhibiting potential positive indications during Screening mandate additional confirmation.
Should the Screening reveal potential positivity, additional hair is extracted from the initial specimen and readied for Extraction. Here, substances are drawn out from the hair at smaller concentrations compared to alternative methodologies, such as urine or oral fluid tests, thus, hair drug analysis stands out as the most complex methodology to execute.
The Confirmation of any positively screened results is achieved using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with initial positive readings go through a washing process before confirmation if required. This complete laboratory procedure, from Accessioning to Confirmation, is scrutinized under the College of American Pathologists (CAP) Hair criteria and adheres to ISO / IEC 17025 accreditation standards.
