Hair Follicle Drug Testing - Melwood, MD

What it is, How it works

Tracking alcohol and drug usage effectively, hair tests are a potent option. Hair naturally records a timeline of substance use, as biomarkers are preserved within the growing strand's fibers. Collecting hair from near the scalp can yield insights into 90 days of alcohol and drug use. Hair is easy to collect, typically secure against tampering, and straightforward to transport.

A sample size of 1.5 inches with around 200 hair strands—comparable to a #2 pencil's thickness—amounts to 100mg, ideal for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, 150mg is advisable. We suggest measuring the hair on a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair is suitable for collection. "Head hair" refers exclusively to scalp hair, whereas "body hair" encompasses facial and axillary hair among other types.

Process Overview

The four core steps for processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about integrating a sample into the laboratory's system, ensuring shipping and sealing integrity, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data inputs missing from the electronic chain of custody system.

This step consists of a preliminary check for substance misuse. While it's economical to screen out non-usage, positive screens require confirmation for court acceptance. Any initial positive results necessitate further verification.

When a sample tests positive initially, further hair is extracted from the sample for preparation in the Extraction phase. Drug extraction from hair occurs at lower concentrations compared to urine or oral fluid methodologies, marking hair testing as a challenging approach.

Confirmation for any screening result signaling positive is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptively positive samples are washed as necessary. The complete lab procedure—from Accessioning to Confirmation—is assessed under both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards of accreditation.

Benefits of Hair Drug Testing:

• Extended detection timeline: Capable of capturing up to three months of drug use, unlike urine tests which offer a shorter span.
• High tampering resistance: It is hard to manipulate a hair drug test, enhancing result accuracy.
• Provides behavioral trends: Offers a usage pattern over time rather than just recent consumption.

Drawbacks:

• Unable to flag recent usage: Detectable drug presence in hair emerges after nearly a week.
• Expense: Costs are generally higher than alternative testing routes.
• Inconsistent results: Factors like hair color and individual growth rates may impact drug metabolite levels in hair.

Note: Though often dubbed "hair follicle tests", the analysis actually occurs on the hair strand, not the follicle beneath the skin.

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.
