Hair Follicle Drug Testing - Wedgewood, MI

What it is, How it works

As a formidable means for uncovering substance use, hair tests play a significant role. Hair archives a lengthy history of alcohol and drug presence, locking biomarkers within the fibers of its progressively developing strands. When extracted near the scalp, hair offers up to about a three-month detection span for substances, including alcohol. This method of collection is straightforward, tamper-resistant, and convenient for transportation.

Securing a sample measuring 1.5 inches with around 200 hairs (similar to a #2 pencil) from the scalp yields 100mg, the perfect mass for both screening and confirmation. To accommodate EtG, supplementary analyses, and/or screenings beyond 10 panels, 150mg of hair is advisable. Utilizing a jeweler’s scale for weighing the sample is recommended. In circumstances lacking scalp hair, equivalent quantities of body hair may be retrieved. It’s important to note that “head hair” specifically pertains to scalp hair, while “body hair” encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The procedure for analyzing drug test outcomes in a laboratory context encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is concerned with the introductory phase of sample integration into a lab’s system. This procedure ensures the sample’s secure sealing and proper shipment while generating a unique LAN (Laboratory Accessioning Number) and finalizing any omitted data entry not captured by an electronic chain of custody framework.

Screening acts as a preliminary, rapid evaluation for potential drug use. While cost-efficient in discounting drug usage in most cases, any positive screenings must undergo confirmation to hold in legal proceedings. Samples with tentative positive results in Screening necessitate further validation.

Upon an initial positive indication in Screening, additional hair is extracted from the original batch for preparation during the Extraction phase. In this process, hair-derived drug concentrations are extracted at considerably lower levels than other approaches (such as urine or oral fluids), rendering hair drug screening a more sophisticated methodology.

Confirming a positive Screen result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Every sample generating a potential positive is cleansed before confirmation as required. The entire laboratory procedure, from Accessioning to Confirmation, is scrutinized according to both the CAP (College of American Pathologists) Hair certification and ISO/IEC 17025 accreditation protocols.

Advantages of hair drug testing:

• Extended detection range: Hair drug exams reveal substance use over a 90-day span, surpassing the shorter detection period of urine tests.
• Resistant to manipulation: Due to the stringent nature of hair drug tests, cheating the test proves extremely challenging, leading to precise results.
• Chronological usage insight: It delineates a pattern of substance usage covering extended periods rather than recent occurrences alone.

Limitations:

• Lacks immediate detection: Substances become evident in hair about 5-7 days post-use.
• Expense: In contrast to alternative drug screening methods, hair drug tests incur higher costs.
• Variability in outcomes: Elements like hair color and individual differences in growth rates can sway the drug metabolite concentration in hair strands.

Note: Although commonly called "hair follicle tests," the analysis targets the hair strand instead of the underlying scalp follicle.

Why Hair Follicle Testing Beats Urine Testing

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.
