Hair Follicle Drug Testing - Perrytown, AR

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting drug and alcohol use. Hair offers an extended timeline of exposure to alcohol and other substances by embedding biomarkers within the strands. When taken near the scalp, this technique provides around a 3-month window for identification of alcohol and other drugs. Hair is straightforward to obtain, relatively hard to tamper with, and convenient to transport.

A 1.5-inch section of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for testing and validation. For EtG tests, additional panels over 10, or special requests, a minimum of 150mg is advisable. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair is not available, an equivalent portion of body hair may be used. References to head hair are solely about scalp hair. Body hair includes all other types (facial, underarm, etc.).

Process Overview

The process of handling a drug test result in the laboratory is divided into four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step of integrating a sample into a lab’s database. This step ensures the sample’s proper packaging and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any required data entry absent in an electronic tracking system.

Screening provides a preliminary assessment for drugs. Despite being an economically efficient strategy to exclude drug presence in most samples, a positive result in Screening needs confirmation to hold legal weight. Samples that appear positive in Screening need additional verification.

For samples showing potential positive results in the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. This phase involves isolating drugs from hair at concentrations much lower than those in other methods (e.g., urine or saliva), highlighting the complexity of hair drug testing.

Verification of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if required. The full lab procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days prior, unlike urine tests that cover a shorter timeframe.
• Challenging to tamper with: Cheating a hair drug test is highly challenging, enhancing result reliability.
• Archives usage patterns: It provides insights into drug consumption trends over time, beyond immediate use.

Limitations:

• Unable to track recent use: It takes around 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug testing is typically costlier than alternative methodologies.
• Result variability: Factors including hair color and personal variations in growth rate can influence drug metabolite levels in hair.

Note: Even though called "hair follicle tests", the examination focuses on the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine tests in Perrytown, AR, superior detection accuracy and reliability are evident. Hair tests can detect drug use over a longer window, whereas urine tests only identify recent consumption.

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.
