Hair Follicle Drug Testing - Hornersville, MO

What it is, How it works

Hair analysis has emerged as a robust method for detecting drug and alcohol consumption. Hair offers a prolonged record of substance use by encapsulating biomarkers within its fibers as the hair strand grows. When collected near the scalp, hair can reveal alcohol and drug use for up to about a 3-month period. Hair collection is straightforward, relatively resistant to tampering, and easily shipped.

Obtaining a 1.5-inch segment of roughly 200 hair strands (around the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, ideal for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is preferred. We advise measuring the sample weight using a jeweler’s scale. Should scalp hair be unavailable, a comparable amount of body hair can be used. Head hair denotes scalp hair exclusively. Body hair encompasses other types like facial and axillary.

Process Overview

There are four principal steps in laboratory drug test processing: Accessioning, Screening, Extraction, and Confirmation.

Accessioning begins the sample’s journey through a lab’s system, confirming proper sealing and transport, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody system.

Screening provides an initial rapid assessment for substance abuse. While Screening cost-effectively eliminates drug use in most samples, any positive findings require confirmation for legal admissibility. Samples with presumptive positives in Screening require further confirmation.

Should Screening suggest a positive outcome, additional hair is extracted from the initial sample and readied for Extraction. This phase retrieves drugs from hair at a significantly reduced concentration compared to other methodologies (e.g., urine or oral swabs), making hair drug screening one of the most challenging techniques.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are cleansed prior to confirmation as required. All processes from Accessioning to Confirmation are scrutinized under both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests, which feature a shorter detection span.
• Challenge to deceive: Hair drug tests are difficult to manipulate, ensuring more reliable results.
• Offers historical insight: Capable of revealing drug use patterns over a timeframe, beyond just recent activity.

Limitations:

• Unable to detect recent usage: Detection in hair takes around 5-7 days post-exposure.
• Expense: Hair drug tests tend to be costlier than alternative drug testing methods.
• Result variability: Elements like hair color and growth rates can influence drug metabolite concentration in hair.

Note: Commonly called "hair follicle tests", the examination focuses on the hair strand, 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
