Hair Follicle Drug Testing - The Pinehills, MA

What it is, How it works

Regarding substance and alcohol analysis, hair testing is recognized as an influential method. Hair strands can capture biomarkers within their growing fibers, offering an extended overview of alcohol and drug consumption. When collected near the scalp, hair samples can reveal a history of up to 90 days. The process of gathering hair is straightforward, making it resistant to tampering and convenient for transport.

For a proper test, a 1.5-inch section comprising approximately 200 hair strands (similar in width to a #2 pencil) adjacent to the scalp is required, delivering 100mg—ideal for initial checks and confirmations. For EtG, additional screenings, or tests exceeding 10 panels, 150mg is advised. It is recommended to use a jeweler’s scale for measuring. If scalp hair is unavailable, equivalent body hair may be utilized. Referring specifically to head hair pertains only to scalp hair. Body hair encompasses all other varieties (facial hair, axillary, etc.).

Process Overview

The drug testing process in the lab involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the preliminary integration of a sample into the lab system, ensuring the sample's seals and shipping procedures are intact. This step includes assigning a random Laboratory Accessioning Number (LAN) and completing necessary data entries absent from electronic custody chains.

The Screening phase conducts an expedited assessment to identify drug presence. While cost-efficient and sufficient for most cases, a positive screen necessitates confirmation for legal acceptance. Any samples showing a presumptive positive in Screening require subsequent verification.

Should a sample test positively in Screening, more hair is extracted from the original specimen for further analysis. During Extraction, drugs are isolated at notably lower concentrations compared to other methods (such as urine or oral fluids), marking hair testing as a challenging procedure.

Confirmation of any presumptive positive is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive samples undergo washing before confirmation as necessary. The comprehensive process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug assessments can recognize usage up to 90 days, unlike urine tests that offer shorter timelines.
• Challenge to falsify: Hair drug tests are considerably difficult to deceive, enhancing result accuracy.
• Historical perspective: Offers an overview of usage patterns over extended durations, not merely recent activities.

Limitations:

• Inability to detect recent use: Detectability in hair occurs approximately 5-7 days post-consumption.
• Expense: Hair drug tests usually incur higher costs than alternative drug assessment methods.
• Result variations: Factors like hair color and individual growth rates can influence metabolite concentration in hair.

Note: The procedure often labeled as "hair follicle tests" actually evaluates the hair strand rather than the follicle beneath the scalp.

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.
