Hair Follicle Drug Testing - Range, WI

What it is, How it works

Hair exams are increasingly regarded as a robust method for identifying drug and alcohol consumption. Hair captures a protracted record of alcohol and other substances by embedding biomarkers into the growing strand's fibers. When acquired near the scalp, hair offers an approximate 3-month period for detecting alcohol and other drugs. Hair is straightforward to collect, challenging to tamper with, and simple to transport.

A sample spanning 1.5 inches containing roughly 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp yields 100mg, the optimal sample size for screening and confirmation. For EtG tests, add-ons, and/or assessments exceeding 10 panels, a 150mg specimen is recommended. It's advised to weigh the sample using a jeweler's scale. If scalp hair is missing, an equivalent volume of body hair may be chosen. Reference to head hair indicates scalp hair solely. Body hair comprises other types like facial or axillary hair.

Process Overview

The primary phases in laboratory processing of a drug test outcome encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a lab's system, which involves confirming the sample's proper sealing and shipping, assigning it a unique LAN (Laboratory Accessioning Number), and finishing any further data entry that an electronic custody chain system doesn't cover.

Screening provides an initial check for drugs of abuse. While Screening is cost-efficient for ruling out drug usage on most samples, a positive screen must be confirmed for legal acceptance. Any samples that yield a presumptive positive in Screening necessitate a subsequent confirmation.

If a sample shows presumptive positivity at the Screening stage, more hair is extracted from the original specimen for Extraction. In this phase, drugs are isolated from hair at far lower concentrations compared to other methods (e.g., urine or oral fluid), thereby making hair drug screening the most complex methodology to execute.

Confirmation of a positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation as required. The entire lab process from Accessioning to Confirmation is reviewed under the specifications set by the CAP (College of American Pathologists) Hair designation, alongside the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Protracted detection time: Hair drug assessments can trace drug use for as long as 90 days, unlike urine tests, which cover a shorter period.
• Hard to manipulate: The results of a hair drug test are more reliable since it is notoriously hard to manipulate.
• Historic data provision: It supplies a drug use pattern covering a period, not limited to recent consumption.

Limitations:

• Incapable of recognizing recent use: Detection in hair requires approximately 5-7 days post-consumption.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variability: Drug metabolite concentration in hair might vary due to differences in hair color and personal hair growth rates.

Note: Despite often being termed as "hair follicle tests", the analysis targets the hair strand, 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.
