Hair Follicle Drug Testing - Swanton, VT

What it is, How it works

Hair testing is increasingly recognized as a robust method for detecting drug and alcohol consumption. Hair serves as a long-lasting record of alcohol and drug intake by capturing biomarkers within the fibers of the growing hair shaft. When collected near the scalp, hair can offer up to a roughly 3-month detection window for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch segment comprising about 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, the perfect sample for both screening and confirmation. For EtG, additions, and/or testing beyond 10 panels, 150mg of the sample is advisable. We suggest weighing the sample on a jeweler's scale. In cases where scalp hair is not accessible, an equivalent amount of body hair may be used. When we mention head hair, we specifically refer to scalp hair only. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The principal steps in the laboratory processing of a drug testing result comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary processing of a sample into a lab’s system. This process ensures that the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not available via an electronic chain of custody system.

Screening provides an initial rapid assessment for drug abuse. While it is an economical method to rule out drug consumption in most samples, a positive screen must be confirmed to be accepted in court. Any samples showing presumptive positivity in Screening require a follow-up confirmation.

If a sample is presumptive positive during Screening, additional hair is taken from the initial specimen and set up for Extraction. In this phase, drugs are pulled from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), hence hair drug screening is known as the most challenging technique to execute.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as needed. The full laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests which feature a shorter detection period.
• Difficulty to cheat: Hair drug tests are extremely hard to cheat, ensuring more precise results.
• Provides historical data: They offer a record of drug use behavior over a duration of time, not just immediate use.

Limitations:

• Cannot detect recent use: It requires around 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests are typically costlier than other drug testing techniques.
• Variations in results: Elements like hair color and individual hair growth differences can influence the drug metabolite concentration in the hair.

Note: Although often called "hair follicle tests", the analysis involves the hair strand 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. 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.
