Hair Follicle Drug Testing - Grahamtown, MD

What it is, How it works

Hair analysis has emerged as a substantial means for detecting substance use of drugs and alcohol. It offers an extended timeline by capturing biomarkers within the fiber of the hair as it grows. When cut close to the scalp, hair can provide up to a three-month period for detecting alcohol and drugs. It's easy to gather, hard to tamper with, and straightforward to transport.

A 1.5-inch portion consisting of roughly 200 hair fibers (comparable to the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, optimal for screening and confirmation. For tests like EtG, add-ons, or those exceeding 10 panels, 150mg is advisable. The use of a jeweler’s scale for weighing the specimen is suggested. If scalp hair isn't available, a comparable amount of body hair may be used. When mentioning head hair, it specifically refers to scalp hair only. Body hair relates to all other categories (such as facial, axillary, etc.).

Procedure Summary

The procedure for laboratory processing of a drug test encompasses Accessioning, Screening, Extraction, and Confirmation.

Accessioning represents the primary phase of integrating a specimen into a lab's system, which consists of affirming the proper sealing and shipment of the sample, designating a random LAN (Laboratory Accessioning Number), and addressing any further data entry unaccompanied by an electronic chain of custody system.

Screening constitutes an initial rapid examination for substance abuse. While cost-effective for excluding drug usage in the majority of specimens, a positive screen necessitates verification for legal admissibility. Any samples identified as presumptively positive in Screening demand secondary confirmation.

For samples flagged as presumptive positive in Screening, additional hair is obtained from the original specimen and readied for Extraction. At this phase, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), which renders hair drug screening as the most intricate methodology.

Confirmation of any positive Screening result is performed through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive specimens are cleansed prior to confirmation as required. The complete laboratory process spanning Accessioning to Confirmation is validated under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection window: Hair tests can identify substance use for as long as 90 days, while urine tests present a shorter detection timeframe.
• Minimal risk of tampering: Cheating a hair drug test is highly challenging, thus ensuring more reliable outcomes.
• Historical usage data: It provides a broader history of substance use, as opposed to focusing solely on recent usage.

Drawbacks:

• Delayed detection of recent use: It takes around 5-7 days for substances to become detectable in hair.
• Expense: Generally, hair drug tests incur higher costs compared to other testing methods.
• Variability in outcomes: Hair color and individual variations in hair growth may influence the concentration of drug metabolites present in hair.

Note: Commonly called "hair follicle tests", the evaluation targets the hair strands, 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.
