Hair Follicle Drug Testing - Ali Chuk, AZ

What it is, How it works

Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. The hair essentially captures a prolonged history of substances by preserving biomarkers within the fibers of the developing hair shaft. When obtained near the scalp, it can offer a detection period of nearly three months for both alcohol and drugs. Hair is straightforward to collect, relatively resistant to tampering, and convenient for dispatch.

A sample measuring 1.5 inches with roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for screening and validation. For EtG add-ons and/or tests exceeding 10 panels, a recommendation of 150mg of the sample is suggested. We advise using a jeweler's scale to weigh the specimen. Should scalp hair be unavailable, an equivalent quantity of body hair can be utilized. When referencing head hair, we mean scalp hair exclusively. Body hair encompasses all other types, such as facial or axillary.

Process Overview

The core procedures in the lab analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a sample into a lab's database. It ensures the sample was appropriately sealed and shipped, assigns a random Laboratory Accessioning Number (LAN), and inserts any supplementary information not included by an electronic chain of custody system.

Screening entails a quick preliminary check for drugs of abuse. Although Screening is a cost-efficient tactic for excluding drug use in most samples, any initial positive result must be validated to be court-acceptable. Samples that show a presumptive positive in Screening need a secondary validation.

If a sample reveals a presumptive positive during the Screening phase, additional hair is retrieved from the initial sample for Extraction. In this phase, drugs are extracted from hair at a notably lower concentration than in alternative methods (e.g., urine or oral fluid), contributing to hair drug screening being one of the most intricate methods to execute.

Confirmation for any initial positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and accreditation according to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as long as 90 days in contrast with urine tests which have a brief detection period.
• Hard to manipulate: Manipulating a hair drug test is extremely challenging, enhancing the accuracy of results.
• Supplies historical insights: It can illustrate a trend of drug use over an extended span, not merely recent usage.

Limitations:

• Inability to identify recent usage: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variability: Features like hair color and individual differences in hair growth can impact the concentration of drug metabolites in hair.

Note: Often referred to as "hair follicle tests," the test actually examines the hair strand, not the hair 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.
