Hair Follicle Drug Testing - Rand, WV

What it is, How it works

Hair analysis is increasingly recognized as an effective means to identify drug and alcohol consumption. By encapsulating biomarkers within the fibers of an extending hair strand, hair serves as a chronicler of substance use. Obtaining hair close to the scalp can furnish up to about a 3-month time frame for the detection of alcohol and other substances. The process of collecting hair is straightforward, with limited chances of tampering, and it is convenient to transport.

A 1.5-inch portion comprising roughly 200 strands (comparable to the girth of a #2 pencil) proximate to the scalp will yield 100mg of hair, which is ideal for analysis and corroboration. For analyses such as EtG, supplementary tests, or tests beyond 10 panels, a quantity of 150mg is advised. It's prudent to measure the specimen with a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair can be obtained. References to head hair specifically pertain to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory assessment of a drug test outcome encompasses four principal phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the foundational handling of a sample within a laboratory platform. This stage includes validating that the sample was properly sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry that an electronic chain of custody system does not provide.

Screening entails a preliminary rapid assessment for substance misuse. Even though Screening presents a budget-friendly method to exclude drug consumption in most specimens, a positive result from screening necessitates verification to be legally acceptable. Specimens that exhibit presumptive positive results in Screening must undergo further validation.

Should a sample show a presumptive positive in the Screening phase, extra hair is extracted from the initial sample and readied for Extraction. This stage involves extracting substances from hair at notably lower concentrations than other methods (e.g., urine or oral fluid), illustrating why hair drug screening is among the most demanding methodologies.

Confirmation of any positive outcomes from screening employs methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as needed. The comprehensive laboratory stages from Accessioning to Confirmation undergo evaluation under both CAP (College of American Pathologists) Hair classification and accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug consumption for a period of up to 90 days, unlike urine assays that have a more limited detection scope.
• Difficulty in tampering: The challenge in circumventing a hair drug test lends to more precise results.
• Displays historical consumption: It demonstrates a timeline of drug usage, not merely recent activity.

Limitations:

• Inability to detect immediate use: It takes about 5-7 days for drugs to become traceable in hair.
• Cost considerations: Generally, hair drug screening incurs higher costs than alternative drug testing procedures.
• Variability in results: Factors such as hair hue and individual hair growth differences may impact the concentration of drug metabolites in the hair.

Note: While commonly termed as "hair follicle tests," the examination actually focuses on the hair strand and not the follicle beneath the scalp.

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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
