Hair Follicle Drug Testing - Dell City, TX

What it is, How it works

Hair testing has emerged as a potent method for identifying drug and alcohol consumption. It offers a chronicled overview of substance use by encapsulating biomarkers within the hair fibers as they develop. When clipped near the scalp, hair offers an estimated three-month observation span for alcohol and drug presence. Hair collection is straightforward, resists tampering, and is simple to transport.

A 1.5-inch section composed of roughly 200 hair strands (equivalent to a #2 pencil) nearest the scalp yields 100mg of hair, ideal for initial screening and validation. For tests involving EtG, additional assays, and/or more than 10 panels, a specimen weighing 150mg is advisable. It is suggested to weigh the sample with a jeweler’s scale. If scalp hair is lacking, an equivalent quantity of body hair may be procured. Reference to head hair pertains to scalp hair exclusively, whereas body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test outcome consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample's initial integration into a laboratory’s system. This step includes confirming the sample's correct sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and handling any additional information input absent from the electronic chain of custody arrangement.

Screening initiates a rapid inspection for drug abuse markers. While being a budget-friendly strategy to dismiss drug use for the majority of samples, a positive screening necessitates confirmation to be legally valid. Any sample flagged as presumptively positive during Screening requires further confirmation.

Should a sample appear presumptively positive during Screening, additional strands are extracted from the original specimen and readied for Extraction. Here, drug substances are extracted from hair at a lower concentration compared to other methods (for example, urine or oral fluid), which is why hair drug screening is considered the most challenging technique to implement.

Positive screening confirmation is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives receive a pre-confirmation wash if necessary. The complete laboratory sequence from Accessioning to Confirmation is scrutinized under the directives of the CAP (College of American Pathologists) Hair category and adheres to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can recognize drug use spanning up to 90 days, while urine tests have a narrower detection interval.
• Resistance to deception: Manipulating a hair drug test is exceedingly difficult, ensuring higher result accuracy.
• Provides retrospective data: It offers a timeline of drug usage over a duration, not limited to recent consumption.

Limitations:

• Inability to register recent use: Drugs become detectable in hair within roughly 5-7 days.
• Expense: Hair drug tests are typically pricier than other drug testing techniques.
• Result variability: Elements such as hair coloration and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Though commonly termed "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Dell City, TX, hair testing offers superior reliability over traditional urine tests. Hair tests boast a longer detection window, providing up to 90 days of substance history. This extended period greatly surpasses the typical 3-day window of urine tests, offering a more comprehensive view of an individual's habits.

Extended Detection Window

Employers in Dell City, TX, gain a deeper understanding of substance use with hair follicle testing, which uncovers usage history up to 90 days. This extended detection period offers a broader picture of an employee's or applicant's substance history, enabling informed decision-making.

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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
