Hair Follicle Drug Testing - Pepin, WI

What it is, How it works

Regarded as a potent tool, hair testing is vital for detecting drug and alcohol consumption. It offers an extended look into past substance use by capturing biomarkers within the fibers of growing hair strands. When taken near the scalp, hair can furnish a detection period of up to around three months for alcohol and drugs. Hair is easy to gather, relatively hard to tamper with, and straightforward to transport.

To obtain the optimal sample for screening and confirmation, a 1.5-inch batch of roughly 200 hair strands (comparable in thickness to a #2 pencil) closest to the scalp will yield 100mg of hair. For EtG, add-ons, or exams exceeding 10 panels, a 150mg specimen is advised. Using a jeweler’s scale for weighing the specimen is suggested. If scalp hair isn't available, a similar quantity of body hair can be used. Head hair specifically means scalp hair, whereas body hair denotes all other types (facial, axillary, etc.).

Process Overview

There are four primary steps in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of introducing a sample into the lab’s system. This step entails confirming the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain-of-custody system.

Screening includes an initial rapid assessment for drugs of abuse. Although it is a cost-efficient approach to exclude drug usage in the majority of samples, any positive findings need confirmation to be court-admissible. Samples that show presumptive positivity in Screening require secondary confirmation.

In cases of presumptive positivity in the Screening phase, additional hair is retrieved from the initial specimen for Extraction. Here, drug extraction from hair occurs at lower concentrations compared to other methods (like urine or oral fluid), making hair drug screening the most challenging methodology to conduct.

Confirming any positive screening outcome is done via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptively positive samples undergo washing as necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can determine drug usage for up to 90 days, whereas urine tests offer a shorter detection period.
• Challenging to falsify: Cheating on a hair drug test is extremely difficult, thereby increasing the accuracy of results.
• Historical information: It supplies a pattern of drug usage over time, not limited to recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests are typically pricier than other drug testing techniques.
• Result variations: Elements such as hair color and personal hair growth differences can influence the drug metabolite concentration in hair.

Note: Though often coined "hair follicle tests", it's the hair strand itself that is analyzed, not the hair 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. 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.
