Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair captures extended histories of alcohol and drugs by preserving biomarkers within the strands as they grow. When collected near the scalp, hair presents an estimated 3-month period for detecting alcohol and drugs. Hair is straightforward to gather, relatively resistant to tampering, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for screening and confirmation. For EtG, additional tests, and/or analyses beyond 10 panels, a 150mg sample is advised. It's recommended to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a similar amount of body hair can be used. The term head hair specifically denotes scalp hair only. All other hair types (facial, axillary, etc.) are referred to as body hair.
Process Overview
The four primary stages in lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates the sample entry into the lab system. This stage includes confirming proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any ancillary data entry not supplied by an electronic chain of custody system.
Screening functions as an initial rapid assessment for drugs of abuse. Although Screening offers a cost-efficient way to eliminate drug use in most samples, a positive result requires confirmation to be legally admissible. Samples showing presumptive positivity in Screening necessitate subsequent confirmation.
When a sample tests presumptive positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. This stage involves extracting drugs from hair at concentrations far lower than those in other methods (e.g., urine or oral fluid), making hair drug screening the most intricate methodology to execute.
Confirming any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation as required. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
