Hair Follicle Drug Testing - Bethlehem, MD

What it is, How it works

Hair testing has emerged as a potent method for identifying drug and alcohol consumption. Hair serves as a prolonged record of alcohol and other substances by embedding biomarkers within the fibers of the developing hair strand. When sourced near the scalp, hair can offer up to roughly a 3-month timeframe for detecting alcohol and other substances. The collection process is straightforward, tampering is relatively challenging, and shipping is uncomplicated.

A 1.5-inch sample of around 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample size for analysis and verification. For EtG, additional tests, and/or screenings exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for weighing the sample is suggested. If scalp hair isn’t available, a comparable quantity of body hair can be collected. When mentioning head hair, it exclusively refers to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The primary procedural phases in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the preliminary processing of a specimen into a laboratory’s infrastructure. This encompasses ensuring the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody framework.

Screening pertains to an initial rapid assessment for substances of abuse. Although Screening is a cost-efficient strategy to eliminate drug consumption in the majority of samples, a positive result necessitates confirmation for it to be legally presented in court. Samples with presumptive positive results in Screening require a follow-up confirmation.

If a sample shows presumptive positivity during the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are isolated from hair at notably lower concentrations than alternative methods (e.g., urine or oral fluid), making hair drug screening the most intricate method to execute.

Confirmation of any positive Screening findings is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before Confirmation, as needed. The entire laboratory workflow from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests have a more limited detection period.
• Challenging to falsify: Hair drug tests are notably hard to deceive, enhancing result accuracy.
• Offers historical insight: It can reveal a trend of drug usage over time, beyond current use.

Limitations:

• Inability to detect very recent use: Approximately 5-7 days are required for substances to become detectable in hair.
• Expense: Hair drug tests generally incur higher costs compared to alternative drug testing techniques.
• Results variability: Elements such as hair color and individual hair growth variations can affect drug metabolite concentration in the hair.

Note: Though commonly termed as "hair follicle tests", the test evaluates the hair strand rather than the hair 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.
