Hair Follicle Drug Testing - Clinton, KY

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. Hair captures long-term evidence of alcohol and drugs by embedding biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair can offer a detection period of up to about three months for alcohol and drugs. Hair sampling is straightforward, relatively tamper-resistant, and simple to transport.

A 1.5-inch segment consisting of approximately 200 hair strands (comparable to a #2 pencil in diameter) nearest to the scalp yields 100mg of hair, an optimal quantity for both screening and confirmation. For tests such as EtG, add-on panels, or those exceeding 10-panel testing, a 150mg sample is advised. We recommend utilizing a jeweler’s scale for specimen weighing. If scalp hair is unavailable, a similar quantity of body hair can be used. Head hair references pertain exclusively to scalp hair. Body hair encompasses all other hair varieties (e.g., facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial phase where a sample is systematized into the laboratory framework. This includes confirming the proper sealing and shipping of the sample, allocating a random Laboratory Accessioning Number (LAN), and fulfilling any additional data entry requirements absent from the electronic chain of custody framework.

Screening entails a preliminary overview for drugs of abuse. Screening serves as a cost-effective measure to negate drug presence in the majority of samples; however, a positive screen necessitates confirmation for legal admissibility. Any presumptively positive samples in the Screening phase require subsequent confirmation.

Should a sample test presumptively positive in Screening, additional hair from the original sample is utilized and prepared for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which explains why hair drug testing remains the most complex methodology to conduct.

Confirmation of any positive screening is implemented via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleaned prior to confirmation as necessitated. The overall laboratory process spanning from Accessioning to Confirmation is reviewed in view of 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 testing can reveal drug consumption for up to 90 days, unlike urine tests, which have a shorter detection timeframe.
• Hard to deceive: It is notably challenging to deceive a hair drug test, enhancing result accuracy.
• Offers historical insight: It provides insights into drug consumption patterns over durations, not just recent usage.

Limitations:

• Inability to detect recent use: Detection in hair requires approximately 5-7 days post-consumption.
• Expense: Hair drug tests are typically costlier than alternative methods.
• Result variability: Variables like hair color and individual hair growth disparities may influence drug metabolite concentration in hair.

Note: Despite often being labeled as "hair follicle tests", the analysis examines 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. 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.
