Hair Follicle Drug Testing - Knolls, UT

What it is, How it works

Hair screening has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drug use by embedding biomarkers within the hair fibers. When gathered near the scalp, hair can offer up to a 90-day detection period for alcohol and other substances. Hair collection is straightforward, moderately resistant to tampering, and convenient for shipping.

A sample measuring 1.5 inches with approximately 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg, considered ideal for analysis and confirmation. For EtG, additional tests, and examinations exceeding 10 panels, 150mg of the sample is advisable. It's suggested to use a jeweler's scale for measurement. If scalp hair is unavailable, a similar quantity of body hair can be used. When discussing head hair, it specifically means scalp hair, while body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The primary steps in the laboratory handling of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial setup of a sample into a lab's system. This process confirms the sample's proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data input not covered by an electronic custody chain system.

Screening performs a rapid initial assessment for substances. Although Screening offers a cost-effective means to exclude drug use in most samples, a positive screening requires confirmation for legal validity. Samples that show presumptive positive results in Screening need a follow-up confirmation.

For samples showing presumptive positive results in the Screening step, additional hair is taken from the initial sample for Extraction. In this phase, drugs are extracted at a lower concentration than other methods (e.g., urine or oral fluid), making hair drug testing a challenging methodology.

GC/MS, GC/MS/MS, or LC/MS/MS is used to confirm any positive screen results. All presumptive positive samples undergo washing before confirmation when needed. The full process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the accreditation standards of ISO/IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to three months, unlike urine tests which have more limited detection times.
• Hard to manipulate: It is challenging to alter a hair drug test, ensuring more reliable results.
• Records usage patterns: It offers insight into long-term drug use, not merely recent consumption.

Limitations:

• Incapable of identifying recent usage: Drugs become traceable in hair within 5-7 days.
• Expense: Hair drug testing tends to be more costly than other testing methods.
• Result variability: Factors like hair color and individual growth differences can impact drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests", the analysis focuses on the hair strand rather than 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.
