Hair Follicle Drug Testing - Sheridan, MT

What it is, How it works

Hair analysis is now recognized as an effective approach for identifying drug and alcohol consumption. By embedding biomarkers in the strands of growing hair, it offers a comprehensive timeline of alcohol and drugs. When taken near the scalp, hair can reveal substance use over a period of up to 3 months. Hair is easy to gather, hard to tamper with, and simple to transport.

A hair sample of 1.5 inches, consisting of about 200 strands (around the diameter of a #2 pencil) near the scalp, typically yields 100mg of hair, which is the optimal quantity for testing and certification. For EtG, additional substances, or tests beyond 10 panels, a specimen of 150mg is suggested. It's advisable to weigh the sample using a jeweler's scale. If head hair is missing, an equivalent body hair sample may be taken. When discussing head hair, we mean scalp hair exclusively. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The four central stages in processing a lab drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the primary processing of a sample into the lab's system. This means ensuring the sample was properly sealed and sent, allocating a unique LAN (Laboratory Accessioning Number), and completing any extra data not included by an electronic chain of custody system.

Screening is a preliminary swift test for substances of abuse. While it's cost-efficient for excluding drug use in most samples, a positive result requires verification for legal acceptability. Any samples preliminarily positive in Screening necessitate an additional confirmation.

For a sample detected as preliminarily positive in Screening, more hair is collected from the initial sample for Extraction. At this stage, drugs are extracted from hair at much lower levels than other methods (e.g., urine or saliva), making hair drug tests the most complex to conduct.

Verification of any positive Screening is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are washed as necessary before verification. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests identify drug use for as long as 90 days, unlike urine tests with a shorter timeframe.
• Resistance to tampering: Cheating a hair drug test is quite challenging, enhancing result accuracy.
• Offers usage history: It shows a drug usage pattern over time, not merely recent consumption.

Limitations:

• Inability to detect recent use: Detection in hair requires about 5-7 days for drugs to manifest.
• Expense: Hair drug tests typically cost more than other drug test methods.
• Result variability: Factors such as hair color and personal differences in hair growth can influence the drug metabolite concentration in hair.

Note: Though often called "hair follicle tests", the test analyzes 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. 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
