Hair Follicle Drug Testing - Gate City, VA

What it is, How it works

Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. The strands capture biomarkers within their fibers, offering a long-term profile of substance use. When hair is collected near the scalp, it can reveal drug and alcohol activity for up to roughly three months. Hair is easy to gather, not easily tampered with, and simple to transport.

A sample measuring 1.5 inches consisting of around 200 hair strands (roughly the diameter of a #2 pencil) taken closest to the scalp yields 100mg of hair, which is ideal for testing and validation. For EtG, additional tests, or panels beyond 10, a sample size of 150mg is advisable. We suggest using a jeweler's scale for precision. In the absence of scalp hair, an equivalent mass of body hair can be used. When mentioning head hair, this denotes scalp hair exclusively. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The primary stages in lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a specimen into a laboratory's system. This step confirms the proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and fills in any missing data entry not included in an electronic chain of custody system.

Screening entails a preliminary assessment for prohibited drugs. Although Screening is an efficient method to exclude drug use in most samples, positively screened samples require further confirmation for legal admissibility. Samples with potential positive results in Screening are subject to additional verification.

Should a sample show a potential positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this stage, drug compounds are isolated from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), which contributes to the challenge of performing hair drug screening.

Confirming a positive Screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS technologies. Before Confirmation, all samples suspected to be positive are thoroughly cleansed. The comprehensive lab procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair standards and accreditation to ISO / IEC 17025 benchmarks.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can trace substances for as long as 90 days, whereas urine tests offer a shorter traceability period.
• Hard to falsify: Cheating a hair drug test is highly challenging, ensuring more trustworthy outcomes.
• Historical usage data: Provides an overview of drug consumption patterns over time, not just recent use.

Drawbacks:

• Incapable of immediate detection: It requires about 5-7 days for drugs to appear in hair.
• Expensive: Hair drug tests tend to be pricier than alternative testing methods.
• Variable results: Influences such as hair pigmentation and individual growth rates can impact the concentration of drug metabolites in hair.

Note: Although frequently labeled as "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Gate City, VA, the advantages of hair follicle tests over urine tests are clear. With superior detection accuracy, hair tests provide a longer detection window, capturing a history of drug use over months.

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.
