Hair Follicle Drug Testing - Arden, AR

What it is, How it works

The analysis of hair has become recognized as a potent method for identifying drug and alcohol consumption. Hair captures biomarkers within the fibers of its growing strand, offering a prolonged record of substance use. When hair is collected near the scalp, it can reveal drug and alcohol use for up to a 3-month period. Hair collection is straightforward, resistant to tampering, and convenient for shipping.

A sample measuring 1.5 inches long, consisting of roughly 200 strands of hair (approximately the diameter of a #2 pencil), should weigh around 100mg, making it optimal for both screening and confirmation. For tests involving EtG, additional panels, or more than 10-panel assessments, a specimen weighing 150mg is advised. Using a jeweler’s scale for weighing is prudent. If scalp hair cannot be gathered, an equal quantity of body hair can be used. ‘Head hair’ refers specifically to scalp hair, while ‘body hair’ denotes all other types (facial, axillary, etc.).

Process Overview

The laboratory procedure for a drug test result includes four core phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed within a laboratory's framework. This step ensures the sample’s proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and includes any extra data entry not covered by an electronic custody system.

Screening acts as an initial brisk test for the presence of drugs. Although Screening is a cost-focused approach for excluding drug use in most samples, a detected positive screen must be confirmed for courtroom admissibility. Any samples with presumptive positives during Screening demand secondary confirmation.

If Screening results are presumptively positive, additional hair is taken from the original sample for Extraction. Here, the drug concentration in hair is much lower than other methods (e.g., urine, oral fluid), underlining why hair drug testing remains a challenging practice.

Confirmation of positive results during screening utilises GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples indicating presumption of positivity are washed before confirmation when necessary. From Accessioning to Confirmation, the entire lab procedure is evaluated as per the CAP (College of American Pathologists) Hair guidelines and accredited under ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use extending to 90 days, whereas urine tests offer a brief detection period.
• Challenge to manipulate: Tampering with a hair drug test is notably challenging, ensuring more credible results.
• Reveals usage trends: This test can depict a timeline of drug use, unlike assessments that highlight only recent consumption.

Limitations:

• Recent use limitations: Drugs are detectable in hair only after approximately 5-7 days.
• Expense: Hair drug testing incurs greater costs compared to other testing forms.
• Results variability: The concentration of drug metabolites in hair can fluctuate due to factors like hair color and personal hair growth variations.

Note: Often termed "hair follicle tests", this examination actually assesses the hair strand rather than the follicle portion within the scalp.

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.
