Hair Follicle Drug Testing - Zihlman, MD

What it is, How it works

Seen as a potent tool in uncovering alcohol and drug use, hair testing reveals extended histories of these substances, with biomarkers captured within growing hair fibers. Hair collected near the scalp offers a detection timeframe of up to three months for drugs and alcohol. Collection is straightforward, tampering is rare, and shipping is uncomplicated.

A sample measuring 1.5 inches comprising about 200 hair strands (resembling a #2 pencil in size) will yield about 100mg, the best amount for both screening and confirmation. For testing EtG, additional substances, and tests exceeding 10 panels, a quantity of 150mg is advisable. We advocate for measuring the specimen using a jeweler’s scale. If scalp hair is inaccessible, an identical portion of body hair can be used. By head hair, we mean only scalp hair. Body hair pertains to all other types, such as facial and axillary hair.

Process Overview

The primary phases in processing a drug test result within a lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial sample processing within the lab system. This involves validation that the sample was sealed and transported properly, allocation of a random LAN (Laboratory Accessioning Number), and entering any additional necessary data not accounted for by an electronic chain of custody system.

The Screening phase is a swift check for substance abuse indicators. Although cost-effective in excluding drug use in most samples, a positive screen necessitates confirmation to be valid in legal contexts. Any samples testing positive in Screening warrant a secondary confirmation.

For samples that suggest positivity during Screening, additional hair is drawn from the main specimen and prepped for Extraction. At this phase, drugs are extracted from hair at notably lower concentrations than what is possible using alternate methods (e.g., urine or oral fluid), making hair drug screening demanding to execute.

Confirmation of positive screening outputs happens via GC/MS, GC/MS/MS, or LC/MS/MS methods. All tentative positive samples are cleansed prior to confirmation as required. The all-encompassing lab protocol from Accessioning through Confirmation undergoes review under the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair tests can reveal drug use up to 90 days, whereas urine tests test for shorter durations.
• Hard to manipulate: Cheating a hair drug test is tough, which ensures more reliable outcomes.
• Offers historical insights: It tracks drug usage patterns over time, not just recent habit.

Limitations:

• Misses recent usage: Drugs become evident in hair after 5-7 days.
• Expense: Hair testing is generally pricier than alternate drug testing approaches.
• Result variability: Elements like hair color and personal hair growth variations can impact drug metabolite concentration in hair.

Note: Though commonly labeled as "hair follicle tests", the analysis actually targets the hair strand instead of 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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
