Hair Follicle Drug Testing - Whitelaw, WI

What it is, How it works

Recognized as a potent method for identifying drug and alcohol consumption, hair testing offers an extended timeline by embedding biomarkers within the strands' fiber structure. When sampled close to the scalp, hair can capture a 3-month usage history for both alcohol and drugs. The collection process is straightforward, with a lower risk of tampering and easy transportability.

Obtaining a 1.5-inch segment, approximately 200 hair strands (similar in width to a #2 pencil) nearest to the scalp, results in 100mg of hair, which is considered optimal for both screening and confirmation tests. For EtG, supplementary panels, or tests beyond 10 panels, a specimen of 150mg is advised. The weight of the sample can be verified with a jeweler’s scale. If scalp hair is not present, an equivalent amount of body hair can be used. References to head hair imply scalp hair. In contrast, body hair encompasses all other variations (facial, axillary, etc.).

Process Overview

There are four fundamental stages in the lab processing of drug tests: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample enters the lab’s processing system, ensuring it was sealed and transported appropriately, assigning a Laboratory Accessioning Number (LAN), and completing any other necessary data not already provided by an electronic chain of custody system.

Screening is a preliminary evaluation of abuse substances. It’s a cost-effective means of ruling out drug consumption in most specimens, but a positive result in Screening must be confirmed for judicial acceptability. Samples that receive a presumptive positive in the Screening phase require further confirmation.

For samples flagged as presumptively positive in Screening, additional hair is taken from the primary sample set for the Extraction phase. Here, the recovery of drugs from hair occurs at notably lower concentrations than in other types of testing (e.g., urine or oral fluid), emphasizing hair drug screening’s technical demands.

Positive results from Screening undergo GC/MS, GC/MS/MS, or LC/MS/MS for Confirmation. Before Confirmation, all presumptively positive samples are cleansed as necessary. The comprehensive process from Accessioning to Confirmation undergoes scrutiny by the CAP (College of American Pathologists) with specific Hair designation and follows ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use over 90 days, whereas urine tests have a shorter detection window.
• Cheating resistance: Hair drug tests are notably hard to falsify, enhancing result validity.
• Provides usage history: Demonstrates a drug use pattern over time, not solely recent usage.

Limitations:

• Recent detection limitation: Drugs become detectable in hair 5-7 days after use.
• Expense: Hair drug tests tend to be costlier than other testing methods.
• Result variability: Drug metabolite concentrations in hair can vary due to factors like hair color and individual hair growth rates.

Note: Frequently referred to as "hair follicle tests", the examination assesses the hair strand, not the follicle beneath 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.
