Hair Follicle Drug Testing - Williamsport, MD

What it is, How it works

Hair testing has emerged as a noteworthy method for identifying drug and alcohol consumption. Hair retains long-term evidence of alcohol and drugs by embedding biomarkers within its growing strands. When procured near the scalp, it provides a detection period of up to 3 months for drugs and alcohol. Hair is easy to collect, hard to falsify, and straightforward to transport.

A 1.5-inch segment of approximately 200 hair strands (around the size of a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for testing and confirmation. For EtG, additional tests, or screenings beyond 10 panels, 150mg of hair is preferred. It's advisable to weigh the hair on a jeweler's scale. If scalp hair is missing, a comparable amount of body hair may be used. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

Drug testing includes four primary laboratory processing stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the first phase of sampling into a lab's workflow. This involves checking that the sample was securely sealed and shipped, assigning a random LAB (Laboratory Accessioning Number), and adding any data not included by an electronic chain of custody system.

Screening is an initial rapid assessment for drugs of abuse. Though Screening is a cost-efficient way to dismiss drug usage in most samples, a positive result must be verified to be legally valid. Any samples appearing positive in Screening need subsequent confirmation.

If Screening suggests sample positivity, more hair is taken from the original sample for Extraction. This stage involves extracting drugs at a much lower concentration from hair compared to methodologies such as urine or oral fluid, making hair drug screening particularly challenging.

Confirmation involves validating any positive screening via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positives are washed as necessary. From Accessioning to Confirmation, the complete laboratory procedure is supervised under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can trace drug consumption for up to 90 days, unlike urine tests which have a shorter detection period.
• Difficulty to cheat: Cheating a hair drug test is quite challenging, enhancing the accuracy of the outcomes.
• Provides historical data: It showcases a drug usage pattern over time, rather than just recent usage.

Limitations:

• Cannot detect recent use: Drugs become noticeable in hair approximately 5-7 days after use.
• Cost: Typically, hair drug tests are pricier than other drug testing techniques.
• Variations in results: Factors like hair color and personal growth variations can influence drug metabolite concentration in hair.

Note: Although often called "hair follicle tests", the analysis 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. 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.
