Hair Follicle Drug Testing - Guernsey, WY

What it is, How it works

Hair analysis is increasingly recognized as an effective method for detecting drug and alcohol consumption. The strands of hair absorb biomarkers into their fibers as they grow, forming a long-term record of substance use. When taken from near the scalp, hair samples can offer a detection window of up to roughly three months for both alcohol and drugs. Hair is also easy to collect, challenging to tamper with, and straightforward to transport.

A sample size of 1.5 inches from approximately 200 strands of hair (similar in size to a #2 pencil) from the scalp yields 100mg, which is ideal for both screening and confirmation. For in-depth testing such as EtG, add-ons, and/or panels exceeding 10, it is suggested to collect 150mg. We advise using a jeweler's scale to weigh the specimen. Should scalp hair be unavailable, a comparable amount of body hair can be utilized. When discussing head hair, we mean scalp hair specifically. Body hair pertains to all other kinds such as facial or axillary hair.

Process Overview

Processing a drug test result in a lab entails four core steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage where a sample is entered into the lab system. This step involves confirming that the sample was securely sealed and shipped, assigning it a unique Laboratory Accessioning Number (LAN), and completing any outstanding data not covered by an electronic chain of custody system.

Screening serves as a preliminary examination for drug presence. While cost-effective for eliminating drug use in most samples, any positive result requires further confirmation to be legally valid. Samples that suggest the presence of drugs during Screening necessitate an additional verification step.

In cases where the Screening indicates a presumptive positive, additional hair from the initial sample is subjected to Extraction. This process removes drugs from hair at lower concentrations than other methods such as urine or oral fluid tests, highlighting the complexity of hair drug screening.

Confirming any positive Screening findings is done through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a cleansing before confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation is assessed according to both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 standards certification.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug presence for up to 90 days, in contrast to the shorter detection period of urine tests.
• Hard to manipulate: The accuracy of hair drug tests is bolstered by the difficulty of tampering with them.
• Historical insight: A pattern of drug use over time can be identified, not just recent consumption.

Limitations:

• Recent use is undetectable: Drugs require about 5-7 days to become evident in hair.
• Expense: Compared to other drug testing approaches, hair tests tend to be costlier.
• Result variability: Drug metabolite concentrations in hair can vary due to factors like hair color and personal differences in hair growth.

Note: Although commonly called "hair follicle tests", the analysis is conducted on the hair strand itself, 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.

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.
