Hair Follicle Drug Testing - East Crockett, TX

What it is, How it works

Hair testing has emerged as a significant method for identifying alcohol and drug usage. The hair structure captures long-term drug and alcohol histories by preserving biomarkers within its growing fibers. When collected from near the scalp, hair offers a detection period of up to 90 days for substances. Collection is straightforward, it's relatively hard to tamper with, and convenient to transport.

An ideal sample is a 1.5-inch segment of around 200 hair strands (akin to the diameter of a #2 pencil) nearest the scalp, which equates to 100mg of hair, perfect for screening and validation. For EtG, additional screenings, and/or assessments over 10 panels, a sample of 150mg is advised. Using a jeweler’s scale to weigh the sample is suggested. If hair from the scalp isn't accessible, an equivalent amount of body hair is acceptable. "Head hair" refers exclusively to scalp hair, while "body hair" includes all other types (such as facial or axillary hair).

Process Overview

The four principal phases in lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

The Accessioning step handles the initial sample processing into a lab’s system. This phase comprises confirming the correct sealing and shipping of the sample, giving it a randomized LAN (Laboratory Accessioning Number), and filling out any extra data entry absent in an electronic chain of custody system.

Screening consists of an initial brief assessment to detect drugs of abuse. While Screening serves as a cost-efficient method to rule out drug presence in most samples, legal admissibility demands that positive screens undergo confirmation. Samples that preliminarily test positive during Screening necessitate another level of confirmation.

During the Screening phase, if a sample is preliminarily positive, more hair is extracted from the original specimen to prep for Extraction. Here, drug presence is retrieved from hair at notably lower concentrations compared to other methods (such as urine or saliva), making hair drug testing the most intricate method to execute.

Confirmation of any positive screen is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminary positive are cleaned prior to confirmation if required. From Accessioning to Confirmation, the complete lab process is scrutinized under CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 certification.

Advantages of hair drug testing:

• Prolonged detection period: Contrary to urine tests, hair drug tests can reveal drug use for up to 90 days.
• Challenge in falsifying results: The difficulty in deceiving a hair drug test enhances result accuracy.
• Historical use insights: It unveils a drug utilization pattern over time, not merely recent consumption.

Limitations:

• Recent use undetectable: Drugs become noticeable in hair after approximately 5-7 days.
• Expenses: Typically, hair drug tests cost more than alternative drug testing methods.
• Result variability: Hair color and individual growth rate differences may affect metabolite concentration in the hair.

Note: Referred to as "hair follicle tests", it's the hair strand being examined 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.

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.
