Hair Follicle Drug Testing - Oretta, LA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. The fibers of hair strands capture biomarkers, offering a comprehensive history of drug and alcohol use that can be detected for up to about three months when collected near the scalp. Hair collection is straightforward, hard to tamper with, and easy to transport.

A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil) from the scalp provides 100mg, the preferred quantity for both screening and confirmation. For EtG, additional tests, or tests over 10 panels, 150mg is advised. Utilizing a jeweler’s scale to measure the specimen is advisable. Should scalp hair be unavailable, a similar quantity of body hair can be collected. Specifically, head hair refers solely to scalp hair, whereas body hair encompasses all other types (such as facial and axillary hair).

Process Overview

The laboratory process for drug test evaluation comprises four major phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the laboratory's system, confirming proper sealing and shipping, assigning an anonymous LAN (Laboratory Accessioning Number), and completing any further necessary data entry absent in an electronic chain of custody system.

Screening offers a preliminary inexpensive assessment for drug abuse detection. Though Screening can efficiently eliminate the majority of drug use suspicions, legal admissibility requires a confirmed positive result. Samples scoring presumed positive in Screening necessitate an additional confirmation step.

For samples deemed presumptively positive in Screening, extra hair is extracted from the original specimen for the Extraction phase. This process retrieves drugs from hair at significantly lower concentrations in comparison to alternative methods (e.g., urine or saliva), which makes hair drug testing particularly intricate to perform.

Confirmation of each positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if required. The entire laboratory procedure, spanning from Accessioning to Confirmation, is supervised under both the CAP (College of American Pathologists) Hair classification and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Sustained detection period: Hair drug tests reveal drug usage for as long as 90 days, outlasting the shorter detection period of urine tests.
• Resistance to tampering: Cheat methods in hair drug testing are challenging, ensuring higher result reliability.
• Historical consumption data: It provides a drug use timeline, not just reflecting recent use.

Limitations:

• Inability to detect recent intake: Detection in hair takes approximately 5-7 days post drug use.
• Price: Hair drug tests are commonly pricier than other drug testing techniques.
• Result inconsistencies: Elements like hair color and individual growth differences can impact drug metabolite concentration in hair.

Note: The term "hair follicle tests" is misleading as the analysis is performed on the hair strand, not the follicle under 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.
