Hair Follicle Drug Testing - Stalwart, MI

What it is, How it works

Hair analysis has emerged as an influential method for detecting drugs and alcohol use. Hair captures a comprehensive history of alcohol and substance use by embedding biomarkers within the fibers of the developing hair strand. When extracted near the scalp, hair offers up to roughly a 3-month period of detection for substances. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.

A 1.5-inch portion comprising about 200 hair strands (approximating the thickness of a #2 pencil) nearest the scalp provides 100mg of hair, which is the optimal amount for assessment and validation. For EtG and other specific tests exceeding 10 panels, 150mg of hair is advised. We suggest utilizing a jeweler's scale for accurate measurement. If scalp hair is insufficient, an equivalent volume of body hair can be used. When discussing head hair, we refer specifically to scalp hair. Body hair encompasses all other hair types (including facial and axillary hair).

Process Overview

The laboratory processing of drug test results is comprised of four chief steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the laboratory’s workflow. This process includes verifying proper sealing and shipment of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not covered by an electronic chain of custody system.

Screening consists of a preliminary assessment for potential drug presence. Screening serves as an economical method for discounting drug presence in most samples; however, a positive screening still necessitates confirmation for court admissibility. Any screenings yielding presumptive positives require further confirmation.

If a screening result indicates presumptive positivity, additional hair from the original sample is readied for Extraction. In the Extraction phase, drugs are isolated from hair at lower concentrations than found in other techniques (like urine or oral fluid), highlighting the complex nature of hair drug screening.

Confirmation of any positive screening findings is executed via GC/MS, GC/MS/MS or LC/MS/MS technologies. Presumptive positive samples undergo washing prior to confirmation as indicated. The complete laboratory process, from Accessioning through Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair standards and the ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use extending up to 90 days, whereas urine tests typically have a shorter detection span.
• Challenging to deceive: Cheating a hair drug test is notably hard, ensuring more precise results.
• Offers historical insight: It provides a timeline of drug use, not just recent occurrences.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests tend to be pricier compared to other drug testing techniques.
• Result variability: Aspects like hair pigmentation and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Despite being often called "hair follicle tests", the test examines the hair strand and not the subcutaneous hair follicle.

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.
