Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair captures a comprehensive history of substances by embedding biomarkers within the fibers of the hair shaft as it grows. A sample collected near the scalp can yield approximately a 3-month detection timeline for various substances. Hair is easy to procure, challenging to tamper with, and convenient to mail.
A sample measuring 1.5 inches of around 200 hair strands (comparable to a #2 pencil in thickness) situated nearest the scalp provides 100mg of hair, which is ideal for examination and validation. For EtG, additional tests, or panels exceeding 10, a total of 150mg of hair is suggested. It is advised to measure the sample using a jeweler’s scale. Should head hair be unavailable, an equal volume of body hair can be used. Head hair refers exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome encompasses the following four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase where a sample is logged into a laboratory’s framework. This step includes ensuring the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data input absent from an electronic chain of custody system.
Screening entails a rapid preliminary assessment for substance abuse. Although Screening is a cost-efficient approach to eliminating drug use from most samples, a positive result must be verified to stand up in legal settings. All samples that test presumptive positive during Screening necessitate further validation.
Should a sample yield a presumptive positive during Screening, supplementary hair is extracted from the main sample for the Extraction process. In Extraction, drugs are derived from hair at substantially lower concentrations than other procedures (e.g., urine or oral fluid), rendering hair drug testing the most intricate process to undertake.
Confirmation of a positive screen is executed through GC/MS, GC/MS/MS, or LC/MS/MS methods. Before confirmation, all samples that test presumptive positive are cleansed as deemed necessary. The complete laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair criteria and compliance with ISO / IEC 17025 standards.
