Hair Follicle Drug Testing - Heilwood, PA

What it is, How it works

Hair analysis has emerged as a robust method for detecting drug and alcohol consumption. This method offers a substantial history of substance use by embedding biomarkers in the fibers of the hair strands as they grow. Collected near the scalp, hair samples can reveal up to a 90-day usage history for several substances. The process of hair collection is straightforward, resistant to tampering, and convenient for shipping.

A sample measuring 1.5 inches, consisting of around 200 hair strands (equivalent to the size of a #2 pencil) near the scalp, yields approximately 100mg of hair, which is the optimal amount for both screening and verification. For EtG assessments, additional analyses, and tests exceeding 10 panels, a 150mg sample is advisable. It's best to weigh the sample using a jeweler's scale. If scalp hair cannot be obtained, a similar quantity of body hair can be used. Specifically, "head hair" refers solely to scalp hair, whereas "body hair" encompasses all other hair types (such as facial or axillary).

Process Overview

The key stages in the laboratory drug testing process include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the sample's initial entry into a lab's system, ensuring it was properly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and completing any remaining data entry that isn’t covered by an electronic chain of custody system.

Screening is a preliminary examination to detect drug abuse. Though it offers a cost-effective means to identify drug intake for most samples, positive findings from Screening must be confirmed for legal admissibility. In Screening, all presumptively positive samples need validation through a secondary confirmation.

Should Screening indicate a presumptive positive result, additional hair is extracted from the primary specimen and prepped for the Extraction phase. During Extraction, drugs are isolated from hair at much lower concentrations than found in other means (like urine or oral fluid), which explains the complexity of hair drug testing.

Confirmation of any positive screen is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. As needed, all samples that presumptively tested positive are cleansed before confirmation. The entire lab process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 certifications.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for as long as 90 days, whereas urine tests offer a shorter timeframe.
• Cheating deterrent: Hair drug tests are notably difficult to manipulate, enhancing the credibility of their results.
• Chronological data: They can reveal usage patterns over time, beyond just recent intake.

Limitations:

• Inability to detect recent use: Drugs become identifiable in hair roughly 5-7 days after use.
• Expense: Hair testing usually entails a higher cost than other testing methods.
• Result variations: Individual differences like hair color or growth rate can influence drug metabolite levels in hair.

Note: Despite the common term "hair follicle tests," the analysis targets the hair strand above the scalp rather than the follicle itself.

Why Hair Follicle Testing Beats Urine Testing

In Heilwood, PA, hair follicle tests surpass traditional urine tests, offering superior detection and reliability.

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.
