Hair Follicle Drug Testing - Stafford Courthouse, VA

What it is, How it works

Hair testing is now recognized as a significant method for identifying drug and alcohol consumption. Hair captures long-term chemical evidence of alcohol and other drugs, integrating these markers into the hair strand's fibers as it grows. When obtained near the scalp, hair can reflect a detection timeframe of up to approximately three months for alcohol and other drugs. Hair collection is straightforward, challenging to manipulate, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (similar in thickness to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the ideal amount for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It's advisable to measure the sample using a jeweler’s scale. If scalp hair is not available, an equivalent volume of body hair can be used. When referencing head hair, it specifically means scalp hair. Body hair includes all other hair forms (facial, axillary, etc.).

Process Overview

There are four key steps in the laboratory analysis of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary incorporation of a sample into a lab’s system. This step verifies that the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry not addressed by an electronic chain of custody.

Screening offers an initial rapid assessment for substances of abuse. Although cost-effective to eliminate drug usage in most samples, a positive screen must be verified to be legally valid. Samples that show presumptive positivity in Screening must undergo additional confirmation.

Should a sample yield a presumptive positive result during Screening, more hair is extracted from the initial sample and made ready for Extraction. During this stage, drugs are isolated from hair at a significantly lower concentration versus other methodologies (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.

Any positive results from the screening stage are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptive positive are cleansed as necessary before confirmation. The full lab process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over a span of up to 90 days, in contrast with urine tests which offer a shorter detection period.
• Harder to manipulate: Hair drug tests are notably challenging to deceive, resulting in more reliable results.
• Illustrates a record of use: It charts a history of drug use spanning a period rather than merely recent occurrences.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests are typically costlier compared to alternative drug testing techniques.
• Variability in outcomes: Hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests", the examination is performed on the hair strand itself, 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.
