Hair Follicle Drug Testing - Rohwer, AR

What it is, How it works

Hair analysis is regarded as an effective means for identifying drug and alcohol consumption. Hair records long-term usage by embedding biomarkers within its fibers as it grows. Collected near the scalp, hair can indicate alcohol and drug usage over a span of around 3 months. Hair is easily collected, hard to tamper with, and simple to transport.

A sample measuring 1.5 inches, comprising roughly 200 hairs (about a #2 pencil's thickness) nearest to the scalp, yields 100mg, an optimal sample for testing and verification. For assessments like EtG, add-ons, and testing exceeding 10 panels, a 150mg sample is advisable. It is best to measure the sample on a jeweler's scale. Absent scalp hair, a similar amount of body hair is suitable. Reference to head hair pertains solely to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The key stages in the lab examination of a drug test include Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the sample's initial integration into the lab system. This phase checks the proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any lacking data entry not covered by an electronic chain of custody procedure.

Screening offers a preliminary drug check. While cost-effective for ruling out drug use in most samples, a positive result in Screening necessitates confirmation for legal validity. Samples presumed positive must undergo further confirmation.

For samples presumptively positive at the Screening phase, more hair is extracted from the initial sample for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug analysis.

Confirmation of any positive screen results is done through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed before confirmation if needed. The entire lab process is audited under CAP (College of American Pathologists) Hair designation and accredited by ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Capable of identifying drug usage for up to 90 days, unlike urine tests with shorter windows.
• Challenging to deceive: Hard to falsify, enhancing result reliability.
• Historical usage data: Offers a timeline of drug use, beyond recent patterns.

Limitations:

• Inability to detect recent intake: It can take 5-7 days for drugs to appear in hair.
• Expense: Typically costlier than alternative testing methods.
• Result disparities: Hair color and growth rate differences can alter metabolite concentrations.

Note: Though sometimes called "hair follicle tests," the analysis focuses on the hair strand, not the follicle below 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.
