Hair Follicle Drug Testing - Manchester, VA

What it is, How it works

The utilization of hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair strands encapsulate a prolonged record of alcohol and drug use by sequestering biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can provide an estimated three-month timeframe for detecting alcohol and drugs. The process of collecting hair is straightforward, relatively tamper-resistant, and simple to transport.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp will amount to 100mg, which is the optimal quantity for both screening and confirmation. For EtG, additional testing, or tests exceeding 10 panels, a specimen weighing 150mg is advised. It is recommended to use a jeweler's scale for weighing the specimen. If scalp hair cannot be provided, a similar quantity of body hair can be collected. References to head hair specifically denote scalp hair. Body hair encompasses all other hair (e.g., facial, axillary).

Process Overview

The key stages in processing a drug test result at the laboratory encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the laboratory's workflow. This process verifies that the sample was appropriately sealed and delivered, allocates a random Laboratory Accessioning Number (LAN), and completes data entry that isn't covered by an electronic chain of custody system.

Screening offers a preliminary assessment for substance misuse. Despite the cost-efficiency of Screening for discounting drug use in most samples, a positive result must be verified to be legally valid. Samples showing presumptive positivity in Screening require subsequent confirmation.

For samples testing presumptively positive during Screening, additional hair is extracted from the existing sample and prepared for Extraction. This phase involves extracting drugs from hair at concentrations lower than those applied in alternative testing methods (e.g., urine or oral fluid), which is why hair drug testing is a challenging methodology.

Confirmation of positive screening results is performed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before confirmation. This laboratory process, from Accessioning to Confirmation, is conducted under the oversight of the CAP (College of American Pathologists) Hair program and meets ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use up to 90 days, in contrast to urine tests which offer a shorter detection period.
• Challenging to circumvent: Hair drug tests are hard to tamper with, ensuring more reliable results.
• Offers longitudinal data: Capable of indicating a timeline of drug use rather than only recent usage.

Limitations:

• Incapable of identifying recent usage: Drugs become detectable in hair only after approximately 5-7 days.
• Expensive: Hair drug testing typically incurs higher costs compared to other testing methods.
• Result variation: Elements like hair color and individual hair growth vary, affecting drug metabolite concentration.

Note: Although often referred to as "hair follicle tests," the assessment targets the hair strand, not the underlying 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.
