Hair Follicle Drug Testing - Oakton, VA

What it is, How it works

Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. Hair records biomarkers of drugs and alcohol within the fibers of the hair strand as it grows, offering a prolonged history. When sourced near the scalp, hair can indicate substance use over a span of nearly three months. Collecting hair is straightforward, hard to tamper with, and convenient to send for analysis.

An optimal sample consists of a 1.5-inch segment composed of roughly 200 hair strands (equivalent to the thickness of a #2 pencil) close to the scalp, resulting in 100mg of hair, which is suitable for testing and verification. Should EtG enhancements or examinations exceed 10 panels, acquiring 150mg is advised. Utilizing a jeweler’s scale to weigh the sample is suggested. If head hair is not accessible, a similar quantity of body hair may be used. "Head hair" is specifically scalp hair, while "body hair" encompasses all other types such as facial and axillary hair.

Process Overview

The laboratory handling of a drug test outcome follows four primary procedures: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the primary processing of a specimen within a lab's framework. Tasks include ensuring the sample’s seal and shipping integrity, assigning it a unique LAN (Laboratory Accessioning Number), and completing any supplementary data management not available through electronic chain of custody systems.

Screening is a preliminary assessment for the presence of drugs. Although a cost-efficient approach for most cases, a positive screen necessitates validation to be considered legitimate in legal proceedings. Samples flagged as presumptive positives during Screening demand further confirmation.

Samples deemed presumptive positives at the Screening stage see additional hair extracted from the initial batch and prepared for Extraction. During Extraction, drugs are isolated from the hair at lower concentrations than other methods (like urine or oral fluid), making hair drug screening the most complex methodology.

Any positive finding during the Screening process is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Presumptive positive samples are cleansed prior to final confirmation if necessary. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under CAP (College of American Pathologists) Hair standards and accredited to ISO/IEC 17025.

Advantages of hair drug testing:

• Extended detection span: Hair tests can uncover drug use up to 90 days prior, unlike urine tests, which offer a shorter detection scope.
• High resistance to manipulation: Tampering with a hair drug test is notably challenging, enhancing result accuracy.
• Historical insights: A hair test outlines trends in substance use over time rather than recent activities alone.

Limitations:

• Inability to recognize immediate use: Drugs generally require 5-7 days to be traceable within hair.
• Expense: Hair drug examinations often incur higher costs than alternative testing techniques.
• Result variability: Elements such as hair color and individual hair growth rates might influence drug metabolite concentrations in the hair.

Note: Commonly termed as "hair follicle tests," the assessment reviews the hair strand itself, excluding the scalp-based hair follicle.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
