Hair Follicle Drug Testing - Grant, MT

What it is, How it works

Hair examinations are now recognized as an effective resource for identifying alcohol and drug consumption. Hair retains a comprehensive history of these substances by embedding biomarkers within its fibers as it grows. When cut close to the scalp, it provides an approximate 3-month detection window for various substances. Collection of hair samples is straightforward, challenging to tamper with, and convenient to ship.

A 1.5-inch sample comprising around 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for screening and verification. For EtG, additional tests, or panels over 10, 150mg of the sample is advised. It is recommended to use a jeweler’s scale to weigh the sample. If scalp hair is not an option, a similar amount of body hair can be utilized. When discussing head hair, it is specific to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The key stages in laboratory processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a laboratory’s framework. This step involves ensuring the sample's seal and shipment are intact, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data requirements not covered by an electronic chain of custody system.

Screening is a preliminary swift evaluation for substance abuse. Although Screening efficiently rules out drug usage in most samples, positive screens need verification for legal proceedings. Samples with presumptive positives in Screening require subsequent verification.

Should a sample indicate a positive result in the Screening phase, additional hair is extracted from the original sample for the Extraction process. Here, drugs are detected at much lower concentrations in comparison to other methods (such as urine or oral fluid), which is why hair drug testing is the most challenging method to execute.

Confirmation of positive screening outcomes is done via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The entire laboratory process ranging from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Long detection span: Hair drug tests can unveil drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Hard to manipulate: Manipulating a hair drug test is quite challenging, thus rendering more reliable results.
• Offers historical insight: Provides a timeline of drug consumption over the long term, beyond immediate usage.

Limitations:

• Cannot detect recent usage: Approximately 5-7 days are required for drugs to become evident in hair strands.
• Expense: Hair drug tests typically incur higher costs compared to other drug-testing approaches.
• Result variability: Factors such as hair color and personal differences in hair growth can impact drug metabolite levels in hair.

Note: Although often described as "hair follicle tests", the focus is on analyzing 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.
