Hair Follicle Drug Testing - Marked Tree, AR

What it is, How it works

Hair testing is recognized as a robust method for detecting drug and alcohol consumption. The hair captures a historical record of alcohol and drug intake by locking biomarkers within the strands. When sourced close to the scalp, hair offers about a three-month detection timeframe for substances. Its collection is straightforward, tampering is challenging, and it is easy to transport.

A sample of 1.5 inches with approximately 200 hair strands (akin to a #2 pencil's diameter) near the scalp yields 100mg, an optimal amount for both screening and confirmation tests. For EtG, supplementary, and tests exceeding 10 panels, 150mg is suggested. It's advisable to use a jeweler’s scale to weigh the sample. If scalp hair is absent, a comparable quantity of body hair can be used. "Head hair" specifically denotes scalp hair, while "body hair" encompasses other hair types (e.g., facial, axillary).

Process Overview

The drug test laboratory process consists of four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial sample integration into a lab's system, ensuring proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing data entries not available via the electronic chain of custody system.

Screening acts as a preliminary check for drug presence. Although it serves as a cost-efficient way to dismiss drug use in most cases, a verified result via Screening requires confirmation to be court admissible. Samples testing positive during Screening necessitate a subsequent confirmation step.

Should a sample test positive during Screening, additional hair is selected from the original sample for Extraction. Here, drug removal from hair occurs at considerably lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug analysis.

Confirmation of positives from Screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Necessary washing of presumptive positive samples precedes confirmation. The laboratory workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair specification and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug analysis can identify drug consumption for up to 90 days, in contrast to urine tests with shorter detection spans.
• Hard to manipulate: Cheating a hair drug test is quite challenging, enhancing the reliability of results.
• Records usage history: Offers insights into drug usage trends over time, not just recent instances.

Limitations:

• Inability to detect recent intake: Drugs become traceable in hair after about 5-7 days.
• Expense: Hair drug tests usually carry a higher cost compared to other techniques.
• Result variability: Drug metabolite concentrations in hair can be influenced by hair color and individual growth variations.

Note: The term "hair follicle tests" is often misused; the analysis targets the hair shaft, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Marked Tree, AR, hair follicle drug testing is increasingly preferred over traditional urine tests due to its superior detection accuracy. Hair test benefits include a longer window of detection, typically up to 90 days, which offers a more comprehensive view of an individual's substance use history.

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.
