Hair Follicle Drug Testing - Baldwin, WI

What it is, How it works

The utilization of hair testing has emerged as an effective method for identifying alcohol and drug usage. Hair captures a comprehensive historical record of drug and alcohol intake by embedding biomarkers within the growing hair fibers. When sampled near the scalp, hair can reflect substance use over roughly a three-month period. It is straightforward to collect, somewhat resistant to tampering, and convenient to transport.

Acquiring a sample length of 1.5 inches, comprising approximately 200 hair strands (comparable to the thickness of a #2 pencil) from close to the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation purposes. For EtG, supplementary tests, and/or analyses exceeding 10 panels, 150mg is advisable. We suggest weighing the specimen using a jeweler’s scale. If scalp hair cannot be provided, a proportional quantity of body hair may be gathered. References to head hair specifically denote scalp hair, whereas body hair encompasses all other types (such as facial or axillary hair).

Process Overview

The laboratory procedure for processing a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into the lab’s system. This process includes confirming the sample's proper sealing and shipment, assigning an arbitrary LAN (Laboratory Accessioning Number), and entering any additional data not covered by an electronic chain of custody system.

The Screening phase involves a preliminary, rapid examination for drugs of abuse. Although Screening serves as a cost-efficient means to eliminate drug use in most samples, a positive outcome necessitates confirmation to be legally defensible. Samples yielding a presumptive positive from Screening will require a subsequent confirmation step.

When a sample is presumptively positive during the Screening phase, additional hair is taken from the original specimen and prepped for Extraction. During this process, the drug compounds are extracted from hair at significantly lower concentrations compared to other methods (such as urine or saliva), making hair drug screening particularly challenging to execute.

Confirmation of any positive screening result is carried out using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptively positive are adequately washed as part of the confirmation process when necessary. The complete laboratory progression from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation requirements.

Advantages of hair drug testing:

• Extended detection period: Unlike urine tests, hair drug tests can identify drug intake for up to 90 days.
• Resistance to manipulation: The difficulty in altering hair drug test results enhances their reliability.
• Historical insight: It provides a timeline of drug consumption over time, rather than only recent use.

Limitations:

• Inability to identify recent intake: It requires around 5-7 days for drugs to become detectable in hair.
• Expense: Generally, hair drug tests cost more than alternative testing methods.
• Result variability: Elements such as hair color and personal hair growth rates can impact drug metabolite levels in hair.

Note: Commonly known as "hair follicle tests," this test evaluates the hair strand itself, not the follicle underneath the skin.

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.
