Hair Follicle Drug Testing - Dooms, VA

What it is, How it works

Recognized for its efficacy, hair testing stands as a robust method for identifying substance use. Hair captures a longitudinal record of alcohol and drug consumption by embedding biomarkers within the hair shaft. Collected from near the scalp, it offers up to a 3-month detection period for substances. The collection process is straightforward, resistant to tampering, and facilitates convenient shipping.

A sample measuring 1.5 inches and consisting of roughly 200 hair strands, akin to the thickness of a #2 pencil, yields 100mg of hair, the preferred amount for testing. For EtG, additional panels, or analyses beyond 10 panels, 150mg of the sample is suggested. It's advisable to use a jeweler’s scale for measuring. In the absence of scalp hair, an equivalent quantity of body hair serves as a substitute. "Head hair" refers exclusively to scalp hair, while "body hair" includes all other hair types (e.g., facial, axillary).

Process Overview

The drug test laboratory process encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the preliminary integration of a sample into the laboratory’s framework. This step ensures the sample’s correct sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any additional manual data entry absent from an electronic custody chain system.

Screening entails an initial rapid assessment for drug presence. While cost-effective for excluding drug usage in most samples, a positive result in Screening necessitates further validation for courtroom acceptability. Samples indicating presumptive positives in Screening require confirmatory analysis.

For specimens showing presumptive positivity during Screening, additional hair from the initial collection is prepared for the Extraction stage. This phase involves isolating drugs from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screenings particularly challenging to execute.

All positive outcomes in screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive specimens are pre-washed as required before Confirmation. The comprehensive lab process, from Accessioning to Confirmation, aligns with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests, which feature a shorter detection window.
• Hard to falsify: Manipulating a hair drug test is challenging, rendering the outcomes more reliable.
• Offers historical insight: It provides a pattern of substance use over time rather than only recent consumption.

Limitations:

• Inability to identify recent consumption: It typically requires 5-7 days for drugs to appear in hair.
• Expense: Generally, hair drug tests incur higher costs compared to alternate testing methods.
• Result variability: Factors such as hair color and individual growth differences can influence drug metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests," the analysis targets the hair strand, not the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing provides a distinct advantage in Dooms, VA, compared to traditional urine tests. By offering superior detection accuracy, it provides results that are more reliable and difficult to dispute.

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.
