Hair Follicle Drug Testing - Newport News, VA

What it is, How it works

Hair testing is increasingly recognized as an effective means to uncover drug and alcohol use. By encasing biomarkers within the fibers of the hair as it grows, it provides a comprehensive record of substance use. Collected near the scalp, hair offers a detection window of up to roughly three months for alcohol and drugs. The collection process is straightforward, with minimal risk of tampering, and it is convenient to transport.

A hair sample of 1.5 inches, approximately 200 strands (the girth of a #2 pencil) near the scalp, yields 100mg, which is optimal for both initial screening and verification. For those requiring EtG, additional tests, or more than 10 panels, a specimen of 150mg is advisable. We suggest using a jeweler's scale to verify the sample's weight. Should scalp hair be inaccessible, an equivalent portion of body hair can be used. "Head hair" specifically denotes scalp hair. In contrast, "body hair" encompasses other hair types (e.g., facial, axillary, etc.).

Process Overview

The laboratory carries out four fundamental stages to process drug test results: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initially processing a sample within a lab's system. It includes ensuring the sample is properly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody.

Screening serves as an initial, efficient assessment for drug abuse. While cost-effective for eliminating drug usage in most cases, any positive Screening findings must be verified for court acceptability. Samples showing presumptive positives in Screening need additional validation.

Upon a presumptive positive result in Screening, further hair is extracted from the initial sample and readied for Extraction. Here, drugs are extracted from hair at lower concentrations than in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Positive Screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples receive necessary washing before confirmation. The entire lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify substance use for up to 90 days, surpassing the shorter detection span of urine tests.
• Hard to manipulate: Cheating a hair drug test is notably challenging, ensuring result accuracy.
• Records usage patterns: It unveils drug use over time, beyond just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Hair drug testing typically costs more than other methods.
• Result variability: Factors such as hair color and individual hair growth rates can influence drug metabolite levels in hair.

Note: Despite being commonly labeled as "hair follicle tests", the examination is of the hair strand and 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.
