Hair Follicle Drug Testing - Austonio, TX

What it is, How it works

Hair analysis is regarded as a potent method for detecting alcohol and drug consumption. It captures a durable record of these substances by preserving biomarkers within the strands as they grow. When hair is taken near the scalp, it can reveal a detection time frame of up to 90 days for alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and easy to transport.

A sample measuring 1.5 inches and consisting of roughly 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp is needed to obtain 100mg of hair for effective screening and confirmation. For tests involving EtG, additional panels, or those exceeding 10 panels, 150mg is preferred. It's suggested to use a jeweler's scale for weighing. If no scalp hair is available, an equivalent amount of body hair may be gathered. Here, head hair specifically means scalp hair, whereas body hair denotes other types (face, armpit, etc.).

Process Overview

There are four essential phases in lab processing for drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the lab's system. This stage includes ensuring the sample is sealed and transported properly, the allocation of a random LAN (Laboratory Accessioning Number), and the completion of any further data input absent from an electronic chain of custody system.

Screening carries out a quick preliminary check for drug substances. It offers a cost-effective method to exclude drug use in most samples, yet any positive Screening results demand further confirmation for legal validation. Any samples with a presumptive positive during Screening require secondary verification.

In cases of presumptive positive results at the Screening phase, additional hair is extracted from the original specimen for the Extraction stage. This stage involves extracting drugs from hair at notably lower concentrations compared to other methods (e.g., urine or saliva), making hair drug analysis one of the most challenging techniques to execute.

Confirmation of positive screening is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating a presumptive positive are cleansed before undergoing confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is evaluated under the guidelines of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug assessments can reveal drug consumption up to 90 days, unlike urine evaluations which have a shorter detection duration.
• High difficulty to manipulate: It is exceptionally challenging to alter a hair drug test, ensuring high accuracy.
• Offers historical data: It provides insights into a pattern of drug consumption over time, beyond just recent intake.

Limitations:

• Unable to identify recent use: Drugs take around 5-7 days before becoming traceable in hair.
• Expense: Hair drug evaluations tend to be pricier than alternative drug testing approaches.
• Result variability: Differences in hair color and personal hair growth rates can influence the level of drug metabolites detected in hair.

Note: Though often termed "hair follicle tests", the analysis targets the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Austonio, TX, holds significant advantages over traditional urine tests.

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.
