Hair Follicle Drug Testing - Roseau, MN

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol usage. Hair captures biomarkers within the growing strand, offering a long-term history of substance use. When sourced near the scalp, hair can reveal drug and alcohol consumption over a timespan up to three months. It is straightforward to collect, relatively hard to tamper with, and simple to mail.

A 1.5-inch section from around 200 strands (similar to the thickness of a #2 pencil) nearest to the scalp yields 100mg, the optimal sample for analysis. For EtG, additional assessments, and/or tests beyond 10 panels, 150mg of the sample is advisable. Utilize a jeweler’s scale for measuring. If scalp hair is lacking, an equivalent volume of body hair is acceptable. "Head hair" specifically pertains to scalp hair. "Body hair" includes all other varieties (facial, axillary, etc.).

Process Overview

The drug testing laboratory processing involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial stage of entering a sample into a lab system. This step ensures the sample is correctly sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and finalizes any outstanding data entry not completed by an electronic chain of custody process.

Screening is a preliminary check for potential drugs of abuse. Despite being a cost-efficient approach to exclude drug usage in many samples, a positive screen requires confirmation for legal admissibility. Samples that screen positive need verification through additional procedures.

If a sample yields a presumptive positive result during Screening, additional hair is sourced from the original specimen and readied for Extraction. This stage involves extracting drugs from hair, which is less concentrated than other methods (e.g., urine or saliva), contributing to the complexity of hair drug analysis.

Final confirmation of a positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumptive positive samples undergo washing before confirmation when necessary. The entire process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair credentials and is accredited to the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use up to 90 days, unlike urine tests which offer a shorter window of detection.
• Difficult to manipulate: Altering results in a hair drug test is extremely challenging, offering increased accuracy.
• Historical insight: It reveals a pattern of drug usage over time, rather than merely recent use.

Limitations:

• Inability to identify recent usage: Drugs become detectable in hair roughly 5-7 days after use.
• Higher costs: Hair drug tests generally incur higher expenses compared to other methods of drug testing.
• Result variations: Influences like hair color and individual hair growth differences can alter drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests", the analysis is conducted on the hair strands rather than the follicles underneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
