Hair Follicle Drug Testing - Andrews Afb, MD

What it is, How it works

Recognized as a robust tool for spotting substance and alcohol consumption, hair analysis captures biomarker traces within hair fibers. By collecting samples near the scalp, hair can indicate drug and alcohol use for up to a 3-month period. This method is easy to collect, challenging to tamper with, and convenient to send.

A strand sample measuring 1.5 inches consisting of around 200 hairs (similar in volume to a #2 pencil) from the scalp provides 100mg, which is the optimal amount for initial and confirmatory testing. For EtG assessments, additional tests, or panels exceeding ten, 150mg is advised. Utilizing a jeweler’s scale for precise weighing is recommended. In cases where scalp hair is absent, an equivalent quantity of body hair can be collected. Head hair specifically refers to scalp strands, whereas body hair denotes all other hair types like facial or axillary.

Process Overview

The processing of drug test results in the lab involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the specimen integrates into the lab’s system. This involves ensuring correct sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and adding any outstanding data that isn’t part of the electronic chain of custody system.

Screening offers a preliminary evaluation for substances. While a cost-efficient method to exclude drug use in most samples, for court admissibility, confirmed positive results are essential. Presumptively positive Screening samples necessitate secondary confirmation.

Upon a presumptive positive finding at the Screening phase, additional hair is taken from the initial sample and processed for Extraction. In this sector, substance extraction from hair occurs at significantly reduced concentrations compared to other methods (e.g., urine or oral fluid), positioning hair drug testing as the most challenging method to execute.

Positive results from screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples are cleansed before confirmation where applicable. From Accessioning to Confirmation, the entire lab process undergoes reviews matching the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair tests trace drug use events spanning up to 90 days, as opposed to shorter spans for urine tests.
• Resistance to fraud: The difficulty in manipulating a hair test ensures the fidelity of results.
• Historical insight: They capture a broader spectrum of drug use activity over time, rather than just recent behavior.

Drawbacks:

• Inability to detect recent usage: Drugs take about 5-7 days post-use to become discernible in hair.
• Expense: Hair tests typically incur higher costs than alternative testing strategies.
• Result variability: Hair coloration and individual growth differences can influence drug metabolite concentration readings in hair.

Note: Commonly called "hair follicle tests", the analysis evaluates the hair strand, not 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.
