Hair Follicle Drug Testing - Schoeneck, PA

What it is, How it works

Hair analysis is recognized as a significant technique for identifying drug and alcohol consumption. It offers an extensive record of alcohol and drug use by embedding biomarkers within the fibers of the growing hair strand. When taken near the scalp, hair can reveal drug or alcohol usage for a period of roughly three months. It's straightforward to collect, relatively resistant to tampering, and easy to transport.

A 1.5-inch segment consisting of about 200 hair strands (roughly the width of a #2 pencil) closest to the scalp provides 100mg of hair, which is the preferred sample size for analysis. For EtG, supplementary tests, and more than 10 panel tests, 150mg of the specimen is advisable. It is suggested to use a jeweler’s scale for weighing the hair. If head hair is not accessible, an equivalent quantity of body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other types (such as facial or axillary hair).

Process Overview

The drug testing process in a laboratory encompasses four critical steps: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample is initially prepared within the laboratory's system. This stage includes verifying that the sample had been sealed and transported correctly, assigning it a LAN (Laboratory Accessioning Number), and completing any requisite data entry that's not already covered by an electronic chain of custody.

Screening conducts a swift, preliminary assessment for drug presence. Though it's a cost-efficient method for ruling out drug use in most samples, a positive screen must be confirmed to be valid in legal proceedings. All samples with initial positive results from Screening require further verification.

Should the Screening suggest a positive result, additional hair is extracted from the original sample for the Extraction phase. This stage reduces drugs from hair to a far lower concentration than alternative techniques (like urine or oral samples), contributing to the complexity of hair drug screening.

GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed to verify any positive Screening outcomes. All samples preliminarily tested as positive receive a cleansing before Confirmation if required. The laboratory process from Accessioning through Confirmation is rigorously examined per the CAP (College of American Pathologists) Hair criteria and the ISO/IEC 17025 accreditation.

Benefits of Hair Drug Testing:

• Extended detection period: Hair drug testing can identify drug use over a 90-day timeframe, unlike urine tests featuring a shorter detection period.
• Difficult to falsify: Cheating a hair drug test is challenging, ensuring the results' reliability.
• Provides chronological data: It illustrates a timeline of drug use over extended periods, as opposed to recent usage alone.

Challenges:

• Cannot detect recent consumption: It requires about 5-7 days for drugs to become apparent in hair.
• Expense: Hair drug tests often cost more compared to other drug testing methods.
• Result disparities: Factors such as hair color and individual hair growth variations can impact drug metabolite concentrations in hair.

Note: While commonly known as "hair follicle tests", this analysis actually evaluates the hair strand rather than 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.
