Hair Follicle Drug Testing - Aurora, NC

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair can capture a long-term history of these substances by embedding biomarkers within the hair strand as it grows. When cut close to the scalp, hair offers a detection window of up to three months for alcohol and other drugs. The collection process for hair is straightforward, fairly resistant to tampering, and convenient for shipping.

A minimum 1.5-inch segment of approximately 200 strands of hair (about the circumference of a #2 pencil) taken near the scalp will yield 100mg of hair, which is the optimal sample for both screening and confirmation. For tests involving EtG, additional parameters, or those exceeding 10 panels, a 150mg specimen is advised. We suggest using a jewelry scale for weighing the sample. If scalp hair is not present, an equivalent weight of body hair can be gathered. In discussing head hair, we are specifically referring to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves entering the sample into the laboratory's system. This process ensures the sample was properly sealed and transported, assigns it a random LAN (Laboratory Accessioning Number), and addresses any additional data input not managed by an electronic chain of custody system.

During Screening, the sample undergoes an initial assessment for drug presence. Although Screening is a cost-effective method to exclude drug use in most samples, a positive Screening result necessitates confirmation for legal admissibility. Presumptive positive Screenings require a subsequent confirmation.

If a sample tests presumptively positive during Screening, additional hair from the initial specimen is prepped for Extraction. Drugs are extracted from the hair at a lower concentration than in other methods (such as urine or oral fluid), which is why hair drug screening presents a greater challenge.

Confirmation of positive screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are cleansed as necessary before confirmation. The complete laboratory process, from Accessioning to Confirmation, is verified under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a shorter detection period.
• Resistance to tampering: Cheating a hair drug test is highly challenging, making the results more reliable.
• Historical insight: It provides a timeline of drug use over an extended period, not merely recent consumption.

Limitations:

• Unable to detect recent use: Drugs typically become detectable in hair after about 5-7 days.
• Higher costs: Hair drug tests are generally pricier than other drug testing approaches.
• Result variability: Elements like hair color and individual hair growth differences can influence drug metabolite levels in the hair.

Note: Often termed "hair follicle tests," these tests actually analyze the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Aurora, NC, hair follicle testing outshines urine testing by offering superior detection accuracy. Unlike urine, hair tests present a more reliable snapshot of an individual's drug 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.
