Hair Follicle Drug Testing - Port Townsend, WA

What it is, How it works

Regarded as a formidable means for identifying drug and alcohol consumption, hair testing chronicles a persistent record of alcohol and drug presence by embedding biomarkers within the growing hair's fibers. Samples secured close to the scalp can reveal substance use up to roughly a 3-month period. The collection of hair is straightforward, fairly tamper-resistant, and easy to send.

A sample of 1.5 inches, consisting of approximately 200 hair strands (akin to the size of a #2 pencil), nearest the scalp amounts to 100mg, which is the preferred quantity for analysis and verification. For EtG testing, additional tests, or panels exceeding 10, it is advised to use 150mg of hair. We suggest weighing the hair on a jeweler’s scale. If scalp hair is inaccessible, a similar quantity of body hair may be obtained. Reference to head hair specifically implies scalp hair, whereas body hair encompasses other types such as facial or axillary hair.

Process Overview

Four pivotal steps compose the laboratory processing for deriving a drug test result: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing within the laboratory’s framework. This step ensures the sample’s proper sealing and dispatch, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry absent from an electronic chain of custody documentation.

Screening involves conducting an initial, swift examination for drug abuse substances. While Screening efficiently negates the presence of drugs in most instances, any positive result necessitates confirmation for judicial admissibility. Samples testing potentially positive during Screening demand a secondary validation.

When a Screening indicates potential positivity, extra hair is extracted from the primary sample and readied for Extraction. Here, drugs are isolated from the hair at considerably lower concentrations than other methods (like urine or oral fluid), rendering hair drug screening the most intricate form to execute.

Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples are cleansed before confirmation as necessary. From Accessioning to Confirmation, the comprehensive laboratory process is scrutinized under both the CAP (College of American Pathologists) Hair specification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug assessments can identify drug usage for up to 90 days, surpassing the shorter detection period of urine tests.
• Difficult to bypass: Evading detection in a hair drug exam is remarkably challenging, thus enhancing accuracy.
• Offers historical insights: It reveals a timeline of drug usage, beyond mere immediate consumption.

Limitations:

• Incapable of identifying recent use: Drugs typically become detectable in hair after about 5-7 days.
• Expense: Hair drug evaluations are usually costlier than other testing approaches.
• Result inconsistencies: Variations in hair color and individual growth tendencies can influence drug metabolite levels in hair.

Note: Although frequently termed "hair follicle tests," the assay actually examines the hair strand as opposed to the subscalp 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.
