Hair Follicle Drug Testing - Weston, MN

What it is, How it works

Hair testing is regarded as an effective method for detecting drug and alcohol consumption. Hair captures biomarkers within its fibers, offering a historical record of drug and alcohol use over time. When hair is obtained close to the scalp, it can reflect a detection period of up to around three months for drugs and alcohol. Collection is straightforward, it is challenging to tamper with, and it is easy to transport.

A 1.5-inch sample, comprising about 200 hair strands (roughly the size of a #2 pencil) taken closest to the scalp, will provide 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of the sample is suggested. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair isn't available, a comparable quantity of body hair may be used. "Head hair" refers exclusively to scalp hair, while "body hair" includes hair from other body areas (such as facial or axillary hair).

Process Overview

The primary four steps in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is integrated into the lab system. This step ensures the sample was properly sealed and transported, assigns a random Laboratory Accessioning Number (LAN), and addresses any additional data entry not covered by an electronic chain of custody.

In Screening, an initial evaluation is conducted to identify drugs of abuse. While this step is a cost-efficient approach to rule out drug use for most samples, any positive findings require validation to be legally accepted. Thus, samples testing presumptively positive must undergo confirmation.

If there is a presumptive positive outcome during Screening, additional hair from the original sample is set aside for Extraction. This phase involves pulling drugs from hair at much lower concentrations compared to other methods such as urine or oral fluid testing, why hair drug testing is considered a challenging technique to master.

Positive results from Screening undergo Confirmation via methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are pre-washed when necessary before confirmation. The process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation as well as ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for up to 90 days, in contrast to shorter timeframes with urine tests.
• Reduced potential for tampering: Extremely difficult to falsify results, enhancing test reliability.
• Chronological use data: Offers insight into drug consumption patterns over time, not merely recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair only after about 5-7 days.
• Higher cost: Hair drug tests typically incur greater expenses than other testing types.
• Result variability: Elements like hair color and individual hair growth rates can influence the levels of drug metabolites in hair.

Note: Frequently termed as "hair follicle tests", the examination analyzes 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.

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.
