Hair Follicle Drug Testing - District Heights, MD

What it is, How it works

Hair analysis has gained recognition as a significant method for detecting the consumption of drugs and alcohol. The strands of hair capture long-term evidence of these substances by embedding their biomarkers within. When sourced near the scalp, it offers a detection window of up to around three months for drugs and alcohol. It's easy to collect, challenging to tamper with, and straightforward to transport.

A segment of hair measuring 1.5 inches and consisting of roughly 200 strands (similar in width to a number 2 pencil) adjacent to the scalp furnishes 100mg, which is the optimum amount for both screening and verification processes. For EtG and additional testing exceeding 10 panels, 150mg of hair is suggested. Utilize a jeweler's scale for precise measurement. In the absence of scalp hair, an equivalent mass from body hair is needed. 'Head hair' denotes specifically scalp hair, while 'body hair' pertains to all other forms (like facial and axillary hair).

Outline of the Procedure

In the lab assessment of drug test results, four key procedures are followed: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial preparation of the sample into a lab's database, ensuring the sample is correctly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and inserting any additional necessary information not available through an electronic chain of custody.

Screening constitutes a preliminary swift assessment for drugs of abuse. While this process is cost-effective for eliminating the majority of samples from drug consumption suspicion, any positive findings necessitate verification for court acceptance. Samples identified as potentially positive during Screening need further confirmation.

Should a sample show potential positivity during Screening, extra hair from the original sample is prepared for Extraction. This phase involves extracting drugs from the hair at much fainter concentrations than found in other samples (like urine or oral fluid), posing hair testing as the most challenging method to execute.

Confirmation of positive Screening results proceeds through GC/MS, GC/MS/MS, or LC/MS/MS methods. All initially positive samples undergo cleaning before Confirmation as required. The full lab sequence from Accessioning to Confirmation falls under the oversight of both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 guidelines.

Pros of hair drug testing:

• Extended detection period: Hair analysis can identify drug use spanning back up to 90 days, unlike urine tests with a brief detection timeframe.
• Challenging to falsify: The difficulty of cheating this method enhances the fidelity of the findings.
• Supplies historical data: It outlines a trend in substance use over time, not limited to recent activity.

Drawbacks:

• Incapable of indicating recent usage: Drugs typically become perceptible in hair within 5-7 days.
• Expense: Hair analysis usually incurs greater costs compared to other drug testing techniques.
• Result variability: Factors like hair shade and individual growth rates might influence the concentration of drug metabolites within hair.

Note: While commonly termed as "hair follicle tests", the evaluation concerns the hair strand itself, excluding the follicle beneath 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.

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.
