Hair Follicle Drug Testing - Nokomis, IL

What it is, How it works

Hair testing is recognized as an influential method for identifying drug and alcohol consumption. Hair captures long-term data regarding substances, as biomarkers are embedded in the growing hair strand's fibers. When acquired near the scalp, hair can offer up to an estimated 3-month timeframe for detecting substances. Hair collection is straightforward, relatively tamper-proof, and easy to transport.

A standard 1.5-inch sample of about 200 hair strands (about the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for analysis and verification. For EtG, additional assessments, and/or panels exceeding 10 drugs, it is advisable to use 150mg of the sample. Utilizing a jeweler’s scale for weighing the sample is advised. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

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

Accessioning involves the foundational processing of a sample within a laboratory's system. This entails confirming the correct sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening offers an initial rapid analysis for possible drug use. While it is a budget-friendly strategy to discount drug consumption in most cases, a positive outcome must be verified for legal acceptability. Samples with a presumptively positive Screening outcome require follow-up confirmation.

If Screening suggests positive results, additional hair is extracted from the initial sample and processed for Extraction. During this stage, drugs are drawn from hair at considerably lower concentrations compared to other methods (ex. urine or oral fluid), establishing hair drug tests as the most intricate method to execute.

Any positive screening must be validated through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo necessary washing before confirmation. The complete laboratory sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug consumption for up to 90 days, in contrast to the shorter detection period of urine tests.
• Challenging to manipulate: Cheating in a hair drug test is highly unlikely, which enhances result accuracy.
• Shows historical use: It can reveal a drug use pattern over some time, rather than merely recent use.

Limitations:

• Inability to detect recent use: It typically takes about 5-7 days before drugs are noticeable in hair.
• Expense: Hair drug tests generally cost more than other testing procedures.
• Result variability: Aspects such as hair color and individual hair growth rates can influence the level of drug metabolites in hair.

Note: Though commonly termed as "hair follicle tests", the testing focuses on analyzing 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.
