Hair Follicle Drug Testing - Walnut, MS

What it is, How it works

Regarded as a potent method, hair testing effectively identifies alcohol and drug usage. Hair retains extensive insights into the prolonged consumption of alcohol and drugs by capturing biomarkers within its fibers. When collected near the scalp, hair can offer a detection window for alcohol and drugs lasting up to approximately three months. The collection of hair is straightforward, resistant to tampering, and convenient for shipment.

A sample of around 200 hair strands, 1.5 inches long (similar to the diameter of a #2 pencil) taken closest to the scalp, yields 100mg of hair, which is optimal for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg specimen is advocated. It is advisable to use a jeweler's scale to weigh the specimen. In absence of scalp hair, an equivalent amount of body hair can be collected. The term 'head hair' refers exclusively to scalp hair, while 'body hair' encompasses all other hair types (including facial and axillary hair).

Process Overview

The four fundamental steps in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning signifies the initial integration of a sample into a laboratory system. This step involves verifying the proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing data entry if not furnished by an electronic chain of custody system.

Screening offers an expedited evaluation for drugs of abuse. While a cost-efficient strategy for ruling out drug use in most samples, a positive screen necessitates confirmation for legal admissibility. Presumptive positives in Screening require secondary confirmation.

If a sample evidences a presumptive positive in the Screening stage, additional hair is drawn from the original sample and readied for Extraction. Herein, drugs are extracted from hair at notably lower concentrations than other methodologies (like urine or oral fluid), underscoring the complexity of conducting hair drug screening.

Confirmation of any positive screen outcome is executed via GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo necessary washing before confirmation. The comprehensive laboratory process, from Accessioning through Confirmation, is scrutinized according to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, contrasting with the shorter detection range of urine tests.
• Tamper resistance: The difficulty in cheating a hair drug test enhances result accuracy.
• Historical insight: It reveals long-term drug usage patterns, rather than merely recent consumption.

Limitations:

• Incapacity to detect recent usage: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Typically, hair drug tests incur higher costs compared to other drug testing techniques.
• Variable results: Elements like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests," the testing process examines 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.
