Hair Follicle Drug Testing - Christiansburg, VA

What it is, How it works

The examination of hair is recognized as an effective resource for detecting drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drug intake by embedding biomarkers within the strands as they grow. Hair captured near the scalp can reveal a detection range of up to roughly three months for alcohol and drugs. Collecting hair is straightforward, relatively hard to tamper with, and easily transported.

A sample measuring 1.5 inches comprising approximately 200 hair strands (equivalent to a #2 pencil in thickness) near the scalp yields 100mg, which is ideal for analysis and verification. For EtG, extra tests, and/or extensive panels beyond 10, a 150mg sample is advisable. It's best to measure the sample with a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be used. When discussing head hair, it refers solely to scalp hair, while body hair pertains to all other hair forms (facial, axillary, etc.).

Process Overview

The testing in a lab for drug presence involves four key phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial setup into the lab's database. This step checks the sample was sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and performs any remaining data entry not covered by an electronic chain of custody.

Screening assesses the presence of drugs initially. It's an economical method of confirming the absence of drug use for most samples; however, positive findings in Screening necessitate further validation for legal cases. Samples that test positive in Screening need additional confirmation.

If a sample is positive following Screening, an additional batch of hair from the original sample is prepared for Extraction. This process extracts drugs from hair, requiring detection at a far lower concentration compared to other methods (such as urine or oral fluid), underscoring the complexity of hair drug testing.

Verification of a positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation if necessary. The end-to-end lab process from Accessioning to Confirmation is inspected according to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use up to 90 days, unlike urine tests that have a shorter detection duration.
• Challenging to circumvent: It's quite hard to evade a hair drug test, enhancing result accuracy.
• Shows historical usage: Offers a timeline of drug use over time, not merely recent consumption.

Limitations:

• Cannot detect recent use: Drugs become noticeable in hair about 5-7 days after use.
• Expense: Hair drug tests tend to be pricier than other drug testing techniques.
• Outcome variations: Different factors like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests," the examination targets the hair strand, not 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.
