Hair Follicle Drug Testing - Bladensburg, MD

What it is, How it works

Hair testing is regarded as a highly effective method for detecting drug and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers within the strands of the hair as it grows. When obtained near the scalp, hair can offer a detection period of up to around three months for various substances. Hair is straightforward to gather, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch sample consisting of approximately 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for both screening and confirmation purposes. For EtG, additional tests, and/or screenings beyond 10 panels, 150mg of the sample is advised. It is suggested to weigh the sample using a jeweler's scale. In cases where scalp hair is unavailable, a comparable amount of body hair can be gathered. When mentioning head hair, it specifically refers to scalp hair only. Body hair encompasses all other types (such as facial or axillary hair).

Process Overview

The laboratory processing of a drug testing result encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a specimen into the laboratory's system. This stage involves ensuring the specimen was correctly sealed and transported, generating a unique LAN (Laboratory Accessioning Number), and completing any extra data that the electronic chain of custody system does not provide.

Screening consists of an initial, rapid assessment for drugs of abuse. Although Screening is a budget-friendly method to dismiss drug usage in most specimens, any positive diagnosis requires confirmation for court admissibility. Any specimens that show presumptive positives in Screening must undergo secondary confirmation.

If a specimen registers presumptive positives in the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are withdrawn from hair in significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the most intricate methodologies to execute.

Confirmation of any positive Screening results is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive specimens undergo washing before confirmation if necessary. Every facet of the laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests have the capability of identifying drug use for up to 90 days, whereas urine tests offer a more limited detection period.
• Difficulty to cheat: It is exceedingly challenging to manipulate a hair drug test, resulting in more precise outcomes.
• Provides historical data: It can outline a pattern of drug usage over time, rather than merely recent use.

Limitations:

• Cannot detect recent use: Detection in hair takes roughly 5-7 days for drugs.
• Cost: Generally, hair drug tests are pricier than alternative drug testing approaches.
• Variations in results: Differences in hair color and individual growth patterns can influence drug metabolite concentrations in hair.

Note: Often called "hair follicle tests," the assessment itself examines the hair strand instead of the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
