Hair Follicle Drug Testing - Alleene, AR

What it is, How it works

The analysis of hair has become recognized as an effective method for identifying the consumption of drugs and alcohol. Hair can reveal a longer-term usage of substances as biomarkers are trapped within its growing strands. When collected from near the scalp, hair can reveal up to a 3-month history of alcohol and drug use. Collecting hair is an uncomplicated process, is somewhat resistant to tampering, and can be conveniently shipped.

A sample measuring 1.5 inches consisting of roughly 200 hair strands (equivalent to a #2 pencil's thickness) from the scalp offers 100mg, which is the preferred amount for initial testing and verification. For EtG, additional panels, or beyond 10-panel testing, a specimen weighing 150mg is advised. Consider using a jeweler’s scale to weigh the specimen. If scalp hair cannot be obtained, a comparable quantity of body hair may be substituted. When mentioning head hair, it exclusively refers to scalp hair. Body hair encompasses all other varieties (e.g., facial, underarm).

Process Overview

Key steps in processing a drug test outcome in the laboratory include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial steps of inputting a sample into the lab's processes. It involves confirming the sample was correctly sealed and shipped, assigning it a LAN (Laboratory Accessioning Number), and completing data entry tasks not automated by an electronic custody chain system.

Screening provides a preliminary assessment for signs of substance abuse. While it is an economical method to dismiss drug use in most samples, any positive screening requires further verification to be valid in legal settings. Samples flagged as positive during Screening necessitate additional confirmation.

When a sample passes the Screening phase as positive, extra hair is extracted from the initial sample for the Extraction phase. This phase extracts drug residues from hair at more reduced concentrations than alternative methods (such as urine or saliva), highlighting the complexity of hair drug testing methods.

Confirmation of a positive screen is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples tested positive are cleansed before confirmation if needed. The whole laboratory workflow, from Accessioning to Confirmation, complies with CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: It can reveal drug usage up to 90 days prior, offering a longer detection timeframe than urine tests.
• Resistance to manipulation: The difficulty in tampering with a hair drug test enhances its accuracy.
• Historical insight: It presents an extended pattern of drug use over time, not merely a snapshot.

Limitations:

• Inability to detect recent use: A timeframe of 5-7 days is necessary before substances can be traced in hair.
• Expense: Hair drug tests tend to be pricier compared to other methods.
• Result variability: The concentration of drug metabolites in hair can be influenced by factors like hair color and individual growth differences.

Note: Although commonly called "hair follicle tests", these examinations focus on the hair strand itself rather than the follicle beneath the skin.

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.
