Hair Follicle Drug Testing - Doran, MN

What it is, How it works

Hair analysis is now recognized as a potent means for identifying drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug usage by embedding biomarkers within the fibers of the growing hair shaft. Acquired near the scalp, hair can reveal up to a roughly 90-day usage period for alcohol and other drugs. The process of collecting hair is straightforward, somewhat tamper-resistant, and simple to transport.

A sample measuring 1.5 inches consisting of about 200 hair strands (around the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation processes. For EtG, additional tests, and/or analyses beyond 10 panels, a 150mg sample is suggested. It is advisable to use a jeweler’s scale for measuring the specimen’s weight. If scalp hair is lacking, a comparable quantity of body hair may be used. When mentioning head hair, this specifically pertains to scalp hair. All other types of hair (facial, axillary, etc.) are considered body hair.

Process Overview

The four essential stages in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into the laboratory’s workflow. This step encompasses checking that the sample was appropriately sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and entering any supplementary data not covered by an electronic custody chain.

Screening consists of an initial rapid evaluation for drugs of abuse. While Screening serves as a cost-efficient method to negate drug presence in most samples, any positive result requires confirmation to be valid in legal settings. Samples that show initial positive results in Screening demand a follow-up confirmation.

When a sample exhibits a presumptive positive during Screening, additional hair is extracted from the original sample for Extraction. This phase entails extracting drugs from hair at concentrations significantly lower than other methods (e.g., urine or oral fluid), which makes hair drug screening one of the most challenging techniques to execute.

Confirmation of any positive Screening outcome is pursued via GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive undergo washing before confirmation as necessary. The overall lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair specifications and conformance to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can recognize drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Hard to deceive: Cheating a hair drug test is extremely challenging, thereby enhancing result accuracy.
• Reveals usage history: It depicts a pattern of drug usage over time, not just recent consumption.

Limitations:

• Inability to detect recent use: It necessitates approximately 5-7 days for drugs to be visible in hair samples.
• Expense: Hair drug analyses typically incur higher costs than other drug testing alternatives.
• Result variability: Elements such as hair color and individual differences in hair growth rate can influence the concentration of drug metabolites in the hair strands.

Note: Though often classified as "hair follicle tests", the analysis itself focuses on the hair shaft 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.
