Hair Follicle Drug Testing - White, AR

What it is, How it works

Hair testing is regarded as a compelling method for uncovering drug and alcohol consumption. Hair strands offer a prolonged history of alcohol and drug use by embedding biomarkers within the fibers as they develop. When obtained near the scalp, hair can reveal a detection period of up to roughly three months for alcohol and numerous drugs. Collecting hair is straightforward, relatively hard to tamper with, and easy to send.

A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil in thickness) closest to the scalp yields 100mg of hair—ideal for initial screening and verification. For EtG, supplementary tests, and tests exceeding 10 panels, 150mg of the specimen is advisable. We advocate for weighing the sample on a jeweler's scale. If scalp hair is inaccessible, a similar amount of body hair can be used. Reference to head hair solely denotes scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory workflow for processing drug test results incorporates Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into a laboratory's system, ensuring the sample was securely sealed and transported, allocating a unique LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.

Screening includes an initial rapid assessment for substance abuse. While Screening is an affordable method to exclude drug use for most samples, a positive screening result requires confirmation to be permissible in a legal setting. Any samples with a presumptive positive result in Screening need a subsequent confirmation.

Should a sample show a presumptive positive during Screening, additional hair is extracted from the primary specimen for the Extraction process. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or saliva). This characteristic makes hair drug screening one of the more challenging techniques to administer.

Confirmation of a positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, while urine tests cover a shorter duration.
• Difficulty to deceive: Cheating a hair drug test is exceedingly tough, ensuring more precise results.
• Historical usage patterns: Hair testing reveals drug use trends over an extended timeline, not merely recent consumption.

Limitations:

• Inability to detect recent use: Drugs generally become detectable in hair around 5-7 days post-use.
• Expense: Hair drug testing is often pricier than alternative testing methods.
• Result variability: Drug metabolite concentrations in hair can be influenced by factors such as hair color and individual growth differences.

Note: While often termed "hair follicle tests", the test pertains to analyzing the hair strand itself, 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.
