Hair Follicle Drug Testing - Rosebud, TX

What it is, How it works

Hair testing is now recognized as a potent instrument for detecting alcohol and drug use. It offers a prolonged history by embedding biomarkers within the hair strand fibers as they grow. When sampled near the scalp, hair can offer a detection span of up to three months for drugs and alcohol. Collecting hair is straightforward, somewhat hard to tamper with, and simple to transport.

A hair sample measuring 1.5 inches with approximately 200 strands (comparable to the thickness of a #2 pencil) located nearest to the scalp yields 100mg, the optimal quantity for screening and confirmation tests. For EtG, enhanced panels, and/or tests beyond 10 panels, 150mg of hair is advised. It is recommended to measure the sample on a jeweler’s scale. If scalp hair isn't available, an equal volume of body hair can be obtained. When referring to head hair, it implies scalp hair exclusively. Body hair includes all other hair types like facial, axillary, etc.

Process Overview

The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first stage where a sample is processed into the lab's system. It includes confirming that the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not provided by an electronic chain of custody.

Screening is the preliminary rapid test for substance abuse. While Screening is economical for ruling out drug use in most samples, a positive result must be validated to be valid in court. Positive samples in Screening require a secondary confirmation.

Should a sample test positive in Screening, more hair is taken from the original sample and prepped for Extraction. Here, drugs are extracted from hair at a lower concentration than other methods (e.g., urine or oral fluid), which makes hair drug screening the toughest method to perform.

Confirmation of a positive screening result is performed using GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples are cleaned before confirmation, if necessary. The lab process from Accessioning to Confirmation is reviewed according to the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, while urine tests have a shorter detection span.
• Hard to manipulate: Cheating a hair drug test is very challenging, resulting in more reliable outcomes.
• Chronological data: Provides insight into the pattern of drug use over a duration of time, not merely recent usage.

Limitations:

• Cannot reveal recent consumption: It takes around 5-7 days for drugs to appear in the hair.
• Expense: Hair drug tests usually cost more than other testing methods.
• Result variability: Influences like hair color and personal differences in hair growth can impact drug metabolite levels in hair.

Note: While commonly known as "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Rosebud, TX, hair follicle testing stands out against urine tests. Why? Hair tests boast superior detection accuracy, capable of revealing substance use over a more extended period. Where urine tests might miss sporadic drug use, hair analysis captures a comprehensive history, making it a reliable choice for employers prioritizing safety and compliance in the workplace.

Extended Detection Window

With an extended detection window reaching up to 90 days, hair follicle testing provides employers in Rosebud, TX, a thorough perspective of an individual's drug history. Unlike urine tests, which cover shorter time frames, hair tests deliver insights into long-term substance use, facilitating informed decisions for hiring and maintaining staff.

Tamper-Resistant Testing Method

Hair follicle tests implemented in Rosebud, TX, are largely tamper-resistant. Unlike more vulnerable methods such as urine tests, hair testing significantly deters sample adulteration, ensuring the authenticity of results.

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.
