Hair Follicle Drug Testing - Isola, MS

What it is, How it works

Hair testing is recognized as an effective method to uncover drug and alcohol usage. Hair delivers an extended history of substance use by embedding biomarkers within the hair's growing strands. When hair near the scalp is taken, it offers almost a 3-month detection period for substances. Hair collection is straightforward, challenging to tamper with, and convenient for transport.

A hair sample measuring 1.5 inches and comprising about 200 strands (similar to the thickness of a #2 pencil) near the scalp produces 100mg, ideal for analysis. For EtG, additions, or tests exceeding 10 panels, a 150mg specimen is advised. Using a jeweler’s scale for weighing the specimen is recommended. If scalp hair isn't available, an equivalent amount of body hair is acceptable. Head hair specifically means scalp hair, while body hair denotes any other hair type (such as facial or axillary).

Process Overview

There are four key stages in the lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial sample processing in a lab's system. This process ensures the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not managed by an electronic chain of custody system.

Screening serves as an initial rapid assessment for drug abuse. While this is a cost-effective method to negate drug use in most samples, a positive outcome needs confirmation for court acceptance. Any samples indicating a positive result in Screening require further verification.

Should a sample appear positive in Screening, additional hair is taken from the initial sample for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than methodologies like urine or oral fluid, which is why hair drug testing is particularly challenging.

Confirmation of a positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that are presumptively positive are cleansed before confirmation if required. Each lab step from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection time: Hair drug tests reveal drug use up to 90 days, whereas urine tests offer a more limited detection span.
• Hard to manipulate: Cheating a hair drug test is notably difficult, enhancing result accuracy.
• Shows usage history: It can highlight a pattern of drug use over extended periods rather than isolated instances.

Limitations:

• Unable to identify recent consumption: Drugs typically become detectable in hair within 5-7 days.
• Higher costs: Generally, hair drug testing expenses surpass those of other testing methods.
• Result variability: Variables like hair color and personal differences in hair growth can influence drug metabolite concentrations.

Note: Frequently termed as "hair follicle tests", the assessment actually examines the hair strand, not the underlying scalp follicle.

Why Hair Follicle Testing Beats Urine Testing

In Isola, MS, hair follicle testing surpasses urine tests by providing a longer detection period up to 90 days.

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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
