Hair screening is recognized as a robust method for identifying substance and alcohol consumption. Hair serves as a long-term record for alcohol and other drugs by embedding biomarkers in the strands of hair as they grow. When obtained near the scalp, hair can offer up to nearly a 3-month period for detecting alcohol and other drugs. Hair is easy to gather, somewhat challenging to tamper with, and convenient to transport.
A 1.5-inch portion consisting of about 200 strands of hair (akin to the size of a #2 pencil) closest to the scalp yields 100mg, which is the optimal sample for both screening and confirmation. For EtG, add-ons, and/or evaluations beyond 10 panels, 150mg of the sample is advised. We propose using a jeweler’s scale for the specimen. If scalp hair is absent, a comparable quantity of body hair can be acquired. The term head hair refers strictly to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The key stages in the laboratory procedure of obtaining a drug test result entail Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the early handling of a sample into a lab's system. This process involves ensuring the sample was sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and performing any extra data input not supplied by an electronic chain of custody system.
Screening offers an initial rapid check for substance abuse. Although Screening is a cost-efficient method to eliminate drug use in most samples, a positive screen requires confirmation for admission in court. Samples deemed presumptively positive in Screening necessitate an additional confirmation.
If a sample shows presumptive positivity during the Screening phase, extra hair is extracted from the original sample and readied for Extraction. During this phase, substances are extracted from hair at much lower levels compared to other methods (e.g., urine or oral fluid), making hair drug screening a notably challenging method to execute.
Analytical verification of any positive screening result is undertaken through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positive results undergo washing before confirmation when required. The complete lab process from Accessioning to Confirmation is conducted under the oversight of both the CAP (College of American Pathologists) Hair designation and the accreditation aligned with ISO / IEC 17025 standards.
