Hair Follicle Drug Testing - Tilghman, MD

What it is, How it works

Hair analysis is now regarded as a robust method for identifying drug and alcohol use. Hair captures a prolonged history of alcohol and other substances by embedding biomarkers in the growing hair fiber. When collected near the scalp, hair can furnish up to roughly a 3-month detection period for alcohol and additional drugs. Hair is easy to gather, somewhat resistant to tampering, and simple to transport.

A 1.5-inch snippet of around 200 hair strands (comparable to the diameter of a #2 pencil) near the scalp provides 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional tests, and/or assessments beyond 10 panels, 150mg of the sample is advised. We advise weighing the sample with a jeweler's scale. If scalp hair is unavailable, a similar amount of body hair may be used. When indicating head hair, we specify scalp hair solely. Body hair includes all other types of hair (facial, axillary, etc.).

Process Overview

The four fundamental phases in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial assimilation of a sample into a lab's framework. This step involves ensuring the sample was properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and accomplishing any extra data input not managed by an electronic chain of custody system.

Screening represents an initial rapid assessment for illicit drugs. Although Screening is an economical way to identify drug consumption for the majority of samples, a positive screening must be verified to be legally recognized in court. Any samples that yield a presumptively positive in Screening necessitate a secondary verification.

In instances where a sample is presumptively positive during the Screening phase, more hair is extracted from the original specimen and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than in other techniques (for instance, urine or oral fluid), hence hair drug screening is the most intricate method to administer.

Validation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The complete laboratory course 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:

• Extended detection period: Hair drug analyses can identify drug use for up to 90 days, unlike urine analyses which offer a shorter detection period.
• Challenges in falsification: Cheating a hair drug test is arduous, resulting in more accurate findings.
• Delivers historical insight: It can reveal a timeline of drug consumption over a span of time, beyond recent intake.

Limitations:

• Inability to detect immediate use: Approximately 5-7 days are required for drugs to become noticeable in hair.
• Expense: Hair drug assessments are typically pricier than other drug testing methods.
• Result variation: Aspects like hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Though often termed as "hair follicle tests", the test actually evaluates the hair strand and not the hair 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. 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.
