Hair screening is recognized as an effective method for identifying substance and alcohol consumption. Hair maintains a long-term record of substances by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can offer a detection timeframe of up to roughly three months for alcohol and other substances. Collecting hair is straightforward, fairly resistant to tampering, and easy to transport.
A sample of 1.5 inches, comprising around 200 strands (approximately the width of a #2 pencil) closest to the scalp, results in 100mg of hair, the optimal quantity for analysis and confirmation. For EtG, additional analyses, or tests exceeding 10 panels, 150mg of the sample is advised. It's suggested to measure the sample with a jeweler’s scale. Should scalp hair be unavailable, a similar amount of body hair may be used. References to head hair strictly mean scalp hair. Body hair includes all other hair varieties (such as facial or axillary).
Process Overview
The core steps in the analytical processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the primary handling of a sample into a lab’s framework. This step ensures the sample was accurately sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and manages any supplementary data incorporation not furnished by an electronic chain of custody system.
Screening entails a preliminary assessment for substance misuse. While Screening is a cost-efficient method to eliminate drug use for the majority of specimens, a positive result requires confirmation for legal admissibility. Any samples inferred as positive in Screening necessitate a subsequent validation.
In cases of presumed positive results during Screening, additional hair is extracted from the original sample to prepare for Extraction. Here, drugs are removed from hair at significantly lower concentrations than other approaches (such as urine or oral fluid), making hair drug screening the most complex approach to conduct.
Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples are cleansed before confirmation if needed. The full laboratory sequence from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 standards accreditation.
