Hair Follicle Drug Testing - St. Charles, IL

What it is, How it works

Hair sample analysis is now recognized as an effective means to detect consumption of drugs and alcohol. Hair captures long-term evidence of substances by embedding biomarkers within the strands as they grow. Sampling hair closely to the scalp offers a detection window of nearly three months for various substances. This method is straightforward to collect, challenging to tamper with, and uncomplicated to transport.

Collecting a 1.5-inch segment of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp produces 100mg of hair, an optimal quantity for screening verification. For EtG, additional tests, and/or more extensive panels, 150mg is suggested. It is advisable to weigh the sample using a jeweler’s scale. In instances where scalp hair isn't accessible, a similar quantity of body hair can be used. When mentioning head hair, it exclusively refers to scalp hair. Body hair includes all other types (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result primarily involves these four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning describes the preliminary handling of a sample within a lab’s system. This step entails ensuring the sample's seal and shipment integrity, assigning a unique LAN (Laboratory Accessioning Number), and addressing any additional data entry not captured by an electronic chain of custody.

Screening serves as a preliminary test for controlled substances. Although Screening is an affordable method to exclude drug usage in most samples, positive results must undergo confirmation to be legally valid. Samples with presumptive positive results in Screening require further verification.

For samples identified as presumptively positive during Screening, additional hair is extracted for the Extraction process. Here, drugs are isolated from hair at much lower concentrations than other methods (like urine or oral fluid), thus making hair drug testing one of the more challenging methodologies.

GC/MS, GC/MS/MS, or LC/MS/MS technology is utilized for confirming positive screening outcomes. All samples with presumptive positive results undergo washing before final confirmation if necessary. Every step of the lab process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair tests can trace drug use for up to 90 days, whereas urine tests have a shorter detection period.
• Difficulty to cheat: Hair testing poses a significant challenge for manipulation, leading to more reliable results.
• Provides historical data: It offers insights into a user's drug history over time, not merely recent consumption.

Limitations:

• Cannot detect recent use: Drugs generally take around 5-7 days to appear in hair.
• Cost: Hair testing tends to be pricier compared to alternative drug testing approaches.
• Variations in results: Elements like hair color and individual hair growth rates may alter drug metabolite concentration in hair.

Note: Although sometimes called "hair follicle tests", this assessment evaluates the hair strand itself and 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.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis.
