Hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair fibers retain biomarkers of alcohol and drugs, offering a historical record. Hair samples collected near the scalp can indicate substance use for up to around 3 months. It's easy to gather, hard to alter, and simple to transport.
A 1.5-inch sample consisting of roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg, which is ideal for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg is advisable. It's suggested to use a jeweler’s scale for weighing the specimen. If scalp hair is not available, an equivalent quantity of body hair is acceptable. References to head hair imply scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four primary stages in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is entered into the laboratory system. This step ensures that the sample was sealed and transported correctly, assigns a unique LAN (Laboratory Accessioning Number), and handles any additional data entry absent from an electronic chain of custody system.
Screening is a preliminary assessment for potential drugs of abuse. While Screening is cost-effective for negating drug usage in most samples, a positive screen mandates confirmation for judicial acceptability. Samples showing presumptive positives in Screening need further confirmation.
Should a sample exhibit a presumptive positive during Screening, additional hair is retrieved from the initial collection and prepped for Extraction. During this phase, drug extraction from hair occurs at a lesser concentration than with other approaches (e.g., urine or oral fluid), which makes hair drug testing the most challenging method to conduct.
Confirming a positive screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo a wash before confirmation when necessary. The whole laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation meeting ISO / IEC 17025 standards.
