Hair analysis is now viewed as a robust method for spotting drug and alcohol consumption. The structure of hair strands captures biomarkers, providing an extended timeline of substance use. When hairs are collected from near the scalp, they can reveal drug and alcohol presence up to an estimated three months. Collecting hair is straightforward, it's relatively resistant to tampering, and it's easy to transport.
A 1.5-inch segment comprising approximately 200 strands of hair (similar in size to a #2 pencil) taken closest to the scalp yields 100mg of hair, which is the optimal amount for initial testing and confirmation. For EtG enhancements, or when conducting tests beyond 10 panels, it is advisable to use 150mg of the sample. It is advisable to determine the weight of the specimen using a jeweler’s scale. Should scalp hair not be available, an equivalent quantity of body hair may be used. The term head hair specifically refers to the scalp, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory drug testing workflow is composed of four primary actions: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step where a sample is initially processed into the lab's system. It involves ensuring the sample was appropriately sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and performing any necessary data input absent from an electronic chain of custody system.
Screening offers a preliminary check for substances of abuse. While cost-efficient for excluding drug use in most samples, a positive result from Screening must be validated for legal acceptability. Samples with a preliminary positive result in Screening require further confirmation.
With a preliminary positive screen, extra hair is obtained from the original specimen and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower levels than in other methods (e.g., urine or oral fluid), making hair drug screening one of the most complex methodologies.
Any positive screening findings are validated through GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing preliminarily positive are cleansed prior to validation if necessary. The whole laboratory operation from Accessioning to Confirmation adheres to both the CAP's Hair designation and the ISO / IEC 17025 accreditation standards.
