Hair Follicle Drug Testing - Fayston, VT

What it is, How it works

Hair analysis is regarded as a potent method for identifying drug and alcohol consumption. Hair contains a record of alcohol and drug consumption by embedding biomarkers within the fibers of the developing hair shaft. When harvested near the scalp, hair can offer a detection window of nearly 90 days for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch segment of approximately 200 hair strands (roughly the girth of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the ideal amount for both screening and confirmation purposes. For EtG tests, supplementary tests, and/or panels exceeding 10, a specimen of 150mg is suggested. It's advisable to weigh the specimen with a jeweler’s scale. Should scalp hair be inaccessible, a corresponding quantity of body hair may be gathered. When referencing head hair, this specifically pertains to scalp hair. Body hair encompasses all other varieties (such as facial, axillary, etc.).

Process Overview

The primary steps in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing of a sample within a lab's system. This encompasses confirming the sample's proper sealing and shipping, assigning a randomized LAN (Laboratory Accessioning Number), and finalizing any additional data entry not covered by an electronic chain of custody system.

Screening is an initial rapid assessment for drugs of abuse. While Screening is an economical way to eliminate drug usage in the majority of samples, a positive screen must be verified to be legally permissible. Any samples that show a presumptive positive in Screening necessitate a secondary confirmation.

If a sample appears presumptively positive during Screening, more hair is extracted from the original specimen and readied for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), thus rendering hair drug screening the most challenging methodology to execute.

Confirmation of positive screening results is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation if needed. The comprehensive lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Ample detection window: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests which have a narrower window.
• Cheating is difficult: It's challenging to manipulate a hair drug test, which enhances accuracy.
• Historical data provision: Hair drug tests can reveal a usage pattern over time, rather than just recent usage.

Limitations:

• Inability to detect recent usage: It requires about 5-7 days for drugs to be noticeable in hair.
• Expense: Hair drug tests often cost more than alternative drug testing methods.
• Result variations: Elements such as hair color and the individual's hair growth rate can influence drug metabolite concentration in the hair.

Note: Although commonly called "hair follicle tests", the test examines the hair strand rather than the follicle located under 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.
