Hair Follicle Drug Testing - Okabena, MN

What it is, How it works

The utilization of hair testing has emerged as an influential method for identifying drug and alcohol consumption. Hair offers an extended historical record of alcohol and drug use by encapsulating biomarkers within the fibers of the developing hair strand. When collected proximally to the scalp, hair can offer nearly a 3-month period of detection for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.

A hair sample measuring 1.5 inches, consisting of roughly 200 strands (comparable to the diameter of a #2 pencil) closest to the scalp yields about 100mg of hair, the optimal amount for initial testing and subsequent confirmation. For EtG enhancements and/or tests involving more than 10 panels, a specimen of 150mg is advised. It is suggested to weigh the specimen with a jeweler’s scale. If scalp hair is unavailable, a similar quantity of body hair can be used. In terms of head hair, this refers solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The primary phases in the laboratory processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the foundational processing of a sample within a laboratory’s system. This includes confirming the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic chain of custody system.

Screening is a preliminary assessment intended to identify potential drugs of abuse. While Screening offers a cost-efficient method of excluding drug usage in the majority of samples, a positive screening result requires confirmation to be deemed court admissible. Any samples showing presumptive positives in Screening necessitate further confirmation.

If a sample is deemed presumptively positive at the Screening stage, additional hair will be drawn from the original specimen for Extraction. Within this phase, drugs are extracted from hair at significantly lower concentrations than in other approaches (e.g., urine or oral fluid), highlighting why hair drug testing is one of the most challenging methodologies to execute.

Confirmation of any positive screening outcomes involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing prior to confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, compared to the shorter detection period of urine tests.
• Challenging to alter: It is exceedingly difficult to manipulate a hair drug test, thus yielding more accurate results.
• Provides usage history: It can demonstrate a pattern of drug usage over time, not merely recent use.

Limitations:

• Not suitable for recent use detection: It takes roughly 5-7 days for drugs to become apparent in hair.
• Expense: Hair drug tests are generally costlier than other drug testing methods.
• Result variability: Factors like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: While commonly referred to as "hair follicle tests", the analysis targets 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.

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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix.
