Hair Follicle Drug Testing - Interlochen, MI

What it is, How it works

Hair testing is viewed as a significant method for detecting drug and alcohol consumption. Hair records a comprehensive history of substances by embedding biomarkers within the strands. When sampled near the scalp, hair reveals a detection timeframe of up to three months for various substances. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A segment measuring 1.5 inches, containing approximately 200 hairs (around the diameter of a #2 pencil), directly from the scalp yields 100mg, the optimum amount for analysis. For EtG, additional tests, or those exceeding 10 panels, 150mg is advisable. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair is not present, an equivalent portion of body hair can be used. References to head hair exclusively pertain to scalp hair, while body hair encompasses all other types (such as facial and axillary).

Process Overview

The core phases of lab processing a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes primary processing within the lab’s framework. This process ensures the sample’s seal and shipment are intact, assigns a random Laboratory Accessioning Number (LAN), and completes any missing data entry from an electronic chain of custody.

Screening serves as a preliminary check for substance abuse. Though cost-efficient for dismissing drug use in most samples, a positive screening must be verified for legal acceptance. Any tentative positive samples necessitate a secondary confirmation.

In instances of a presumptive positive result during Screening, additional hair is taken from the original sample for Extraction. At this stage, substances are drawn out of hair at significantly lower concentrations than other methods, such as urine or oral fluids, causing hair screenings to be more challenging.

Positive screenings are confirmed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are tentatively positive are cleaned as needed before confirmation. The complete lab process, from Accessioning to Confirmation, is scrutinized following both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditations.

Advantages of hair drug testing:

• Extended detection: Hair drug tests identify substance use for up to 90 days, a longer span than urine tests which offer shorter periods.
• Resistance to tampering: Hair drug tests are notably hard to manipulate, ensuring higher accuracy of outcomes.
• Showcases usage history: Presents a historical pattern of substance use instead of only recent activity.

Limitations:

• Lack of recent use detection: Approximately 5-7 days are necessary for substances to be traceable in hair.
• Expense: Generally, hair drug tests incur higher costs compared to other testing methods.
• Result variability: Factors such as hair color and growth differences can influence drug metabolite levels in hair.

Note: Despite being called "hair follicle tests", the analysis focuses on the hair strand itself 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.
