Hair Follicle Drug Testing - Brussels, IL

What it is, How it works

Hair testing is recognized as a robust instrument for identifying drug and alcohol consumption. Hair captures long-term biomarker histories of alcohol and drugs within the fibers of the maturing hair strand. When obtained close to the scalp, hair can deliver up to an estimated 3-month detection timespan for alcohol and substances. Hair sample collection is straightforward, challenging to alter, and convenient to transport.

A 1.5-inch piece, comprising roughly 200 hair strands (comparable to the girth of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the perfect sample size for screening and verification. For EtG, add-ons, and/or tests surpassing 10 panels, 150mg of the sample is advised. We suggest utilizing a jeweler’s scale to weigh the specimen. In cases where scalp hair is absent, an equivalent quantity of body hair may be taken. In terms of head hair, it pertains solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test outcome encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step of integrating a sample into the lab’s framework. This includes confirming the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and accomplishing any supplemental data input absent in an electronic chain of custody protocol.

Screening encompasses an initial brisk review for substances of concern. While Screening offers a cost-effective manner to discount drug usage across the majority of samples, it requires a validated confirmation for court admissibility. Samples showing presumptive positivity in Screening necessitate a subsequent confirmation.

Samples registering presumptive positivity within Screening proceed with further hair extraction from the original sample and preparation for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting why hair drug screening is the most intricate methodology available.

Any outcome showing positivity is confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing before confirmation where necessary. The complete laboratory workflow, from Accessioning through to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair categorization alongside ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can uncover drug consumption for up to 90 days, contrary to urine tests with briefer detection periods.
• Improbability of evasion: Manipulating a hair drug evaluation is notably challenging, enhancing result accuracy.
• Historical documentation: Provides insights into drug consumption patterns over time, unlike recent usage assessments.

Limitations:

• Incapable of recent usage detection: Drugs require approximately 5-7 days before becoming detectable in hair.
• Expense: Hair drug testing tends to be more costly versus other testing alternatives.
• Result discrepancies: Elements like hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", the analysis targets the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
