Hair Follicle Drug Testing - New Vienna, OH

What it is, How it works

Hair analysis is recognized as an effective method to identify substance use, capturing alcohol and drug traces within the structure of the hair shaft. By sampling hair near the scalp, a detection window of up to three months can be achieved. The collection process is straightforward, tampering is challenging, and transportation is uncomplicated.

A sample of 1.5 inches consisting of around 200 hair strands (roughly equivalent to the thickness of a #2 pencil) closest to the scalp is optimal, yielding 100mg for analysis. For EtG, additional tests, or panels exceeding 10, a quantity of 150mg is advised. We suggest using a jeweler's scale for accuracy. In the absence of scalp hair, a similar volume of body hair can be used. "Head hair" pertains to scalp hair solely, while "body hair" covers all other types like facial or axillary hair.

Process Overview

Key stages in processing a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates initial sample integration into a lab's system, confirming proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any outstanding data not captured by an electronic chain of custody.

Screening performs an expedited preliminary assessment for drug abuse. Although a cost-effective method to exclude substance use in most samples, any positive result from Screening must be substantiated for legal validity. Presumptive positives from Screening necessitate further affirmation.

If a sample tests positive during Screening, additional hair from the initial batch is used for Extraction, where drugs are isolated at significantly lower concentrations than in alternative methods (e.g., urine or oral fluid), making hair analysis more complex.

Positive Screening outcomes are verified through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives undergo washing prior to Confirmation as required. The comprehensive lab process from Accessioning to Confirmation is subjected to review by CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Capable of revealing drug use up to 90 days, unlike urine tests with shorter windows.
• Hard to falsify: Cheating on a hair drug test is exceedingly difficult, boosting result accuracy.
• Shows usage patterns: It charts substance use over time, not just recent intake.

Limitations:

• Not suitable for recent detection: Substances become identifiable in hair roughly 5-7 days post-consumption.
• Higher expense: Hair tests are typically more costly compared to other methods.
• Result variability: Elements like hair color and personal hair growth rates may influence metabolite concentrations in hair.

Note: Commonly termed "hair follicle tests," the testing focuses on the hair shaft rather than the follicle under the skin.

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. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.

Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.

The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
