Hair Follicle Drug Testing - Wahak Hotrontk, AZ

What it is, How it works

Hair analysis has gained recognition as an effective means for detecting substance use, including drugs and alcohol. Hair locks in biomarkers within its fibers, offering an extended record of substance consumption. When taken near the scalp, hair can reveal usage within a 3-month timeframe. The process is easy to perform, tough to alter, and straightforward to transport.

A 1.5-inch segment of roughly 200 hair strands (equivalent to the dimensions of a #2 pencil) from near the scalp yields 100mg, ideal for initial testing and confirmation. For EtG evaluations or tests exceeding 10 panels, 150mg is preferred. Using a jeweler’s scale for precise measurement is suggested. In the absence of scalp hair, an equivalent quantity of body hair can be used. References to head hair specifically mean scalp hair, while body hair includes other types (e.g., facial, axillary).

Process Overview

The laboratory procedure for drug testing consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating the sample into the lab system, confirming the sample's proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data input not covered by an automated chain of custody.

Screening acts as an initial rapid assessment for drug presence. Though it’s a cost-efficient method to dismiss drug usage in most cases, any positive findings must be verified for legal admissibility. Presumptively positive samples from Screening need further confirmation.

For samples deemed positive in Screening, additional hair is extracted for the Extraction phase. Here, substances are removed from hair at lower concentrations than in other methods like urine or oral fluids, making hair drug analysis particularly challenging.

Confirmation for positive results uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positives are cleansed before confirmation. The full laboratory workflow, from Accessioning to Confirmation, aligns with CAP (College of American Pathologists) Hair guidelines and conforms to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests detect substances up to 90 days, surpassing the shorter timeframe of urine tests.
• Challenge to deceive: Hair drug tests are resistant to tampering, offering more reliable results.
• Historical consumption data: It reveals a pattern over time rather than just recent usage.

Limitations:

• Recent use not detectable: Drugs take 5-7 days to appear in hair.
• Expense: Hair drug tests tend to cost more than alternative testing methods.
• Result variability: Hair color and personal growth differences can influence drug metabolite concentrations in hair.

Note: Despite the common term "hair follicle tests", the analysis focuses on the hair strand, not the follicle itself 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.

In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field.
