Hair Follicle Drug Testing - Pearl City, IL

What it is, How it works

Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair archives a prolonged history of alcohol and other substances by capturing biomarkers within the fibers of the growing strand. When near the scalp, hair can reveal up to about a 3-month period for detecting substances. It is easy to gather, hard to tamper with, and convenient to send.

A 1.5-inch segment of roughly 200 strands (approximately the thickness of a #2 pencil) near the scalp yields 100mg of hair, the optimal sample for both testing and confirmation. For EtG, additions, and/or tests exceeding 10 panels, 150mg is advised. It's best to weigh the sample with a jeweler’s scale. If scalp hair is lacking, a similar volume of body hair can be collected. Referring to head hair implies scalp hair, while body hair includes all other forms (facial, axillary, etc.).

Process Overview

The four fundamental steps in lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where a sample is processed into a lab's system. This step includes confirming proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not captured by an electronic chain of custody system.

Screening serves as an initial rapid assessment for drugs of abuse. Although it's a cost-efficient method for discounting drug usage on most samples, a positive result must be confirmed for legal admissibility. Samples showing a presumptive positive in Screening need subsequent confirmation.

If there is a presumptive positive in the Screening phase, additional hair is gathered from the initial sample for Extraction. In this stage, drugs are extracted from hair at lower concentrations than with other methods (like urine or oral fluid), making hair drug screening the most challenging method to execute.

Confirmation of any positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive are cleansed before confirmation as necessary. The entire process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can show drug use for up to 90 days, unlike urine tests which have a shorter timeframe.
• Hard to manipulate: Cheating a hair drug test is very challenging, enhancing the accuracy of the results.
• Gives historical insights: Reveals a pattern of substance use over time, not just recent usage.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair roughly 5-7 days post-use.
• Expense: Hair drug tests are typically pricier than other testing methodologies.
• Result variability: Factors like hair color and individual growth differences can influence drug metabolite concentration in hair.

Note: Often mislabeled as "hair follicle tests", the analysis is of the hair strand itself, 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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
