Hair Follicle Drug Testing - Marietta, IL

What it is, How it works

Hair examinations have evolved into an effective instrument for identifying substance usage. Hair captures a prolonged record of alcohol and drug intake by embedding biomarkers within the hair strand's fibers as it grows. When gathered near the scalp, hair can offer nearly a 3-month detection timeframe for substances like alcohol. Collecting hair is straightforward, relatively hard to tamper with, and convenient to transport.

A hair sample measuring 1.5 inches and consisting of about 200 strands (around the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for analysis. For EtG, additional testing, or tests exceeding 10 panels, 150mg is advisable. Utilizing a jeweler’s scale is suggested for weighing the sample. If scalp hair is lacking, a similar volume of body hair may be utilized. By head hair, we refer specifically to scalp hair, whereas body hair encompasses all other forms (facial, axillary, etc.).

Process Overview

Drug test laboratory processing encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a laboratory setting. It involves ensuring the sample was secured and dispatched appropriately, generating a LAN (Laboratory Accessioning Number), and completing supplementary data entry lacking in an electronic chain of custody system.

Screening is a rapid preliminary test for drug presence. While cost-efficient, confirming any positive screen is crucial for legal admissibility. Any samples that show tentative positives during Screening must undergo further validation.

In instances of tentative positivity during Screening, extra hair from the initial sample undergoes preparation for Extraction. Drugs are extracted at notably lower concentrations in hair than other methods (such as urine or oral fluids), contributing to hair testing being a particularly complex method to execute.

Confirmation of any positive Screening findings occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive samples undergo washing before confirmation. The full lab sequence, from Accessioning to Confirmation, is evaluated following both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair tests identify substance use up to 90 days, unlike urine tests which offer a shorter timeframe.
• Challenging to manipulate: Manipulating a hair drug test is quite arduous, enhancing result accuracy.
• Yields past usage patterns: It reveals patterns of drug intake over time, beyond just recent usage.

Drawbacks:

• Recent usage undetectable: Hair takes about 5-7 days post-consumption to show drug traces.
• Expense: Hair tests tend to be pricier than alternate drug testing techniques.
• Result variability: Hair color and individual growth disparities can influence drug metabolite concentration in hair.

Note: Commonly termed "hair follicle tests", the analysis actually examines 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.
