Hair Follicle Drug Testing - Byrdstown, TN

What it is, How it works

Hair tests are now recognized as an efficient method for uncovering substance and alcohol consumption. Hair captures extended histories of alcohol and drug usage by embedding biomarkers within the strands during growth. When sourced near the scalp, it can reveal a detection span of almost 3 months for alcohol and other substances. Hair sampling is straightforward, hard to falsify, and convenient to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil) close to the scalp provides 100mg, which is the preferred quantity for both assessment and verification. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg sample is suggested. Utilizing a jeweler’s scale to weigh the sample is advised. In the absence of scalp hair, a comparable volume of body hair can be used. In contexts mentioning head hair, we mean scalp hair exclusively. Body hair comprises all alternative hair types (such as facial, axillary, etc.).

Process Overview

The process of laboratory drug test evaluation includes four core stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the specimen is initially processed into a lab’s system. This phase covers confirming the secure sealing and shipping of the specimen, allocating a random LAN (Laboratory Accessioning Number), and accomplishing any further data input absent from an electronic custody chain system.

Screening offers an initial swift drug misuse assessment. Although Screening is affordable for largely excluding substance use in most samples, legal admissibility requires confirmation of any positive screen. Any samples positively flagged during Screening need subsequent confirmation.

For samples preliminarily positive in Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at concentrations lower than those found in other methods (e.g., urine or oral fluid), hence hair drug screening is challenging to execute.

Confirmation of any positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS. All potential positive samples are cleansed before confirmation if necessary. The all-encompassing laboratory procedure from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can track substance use up to 90 days, unlike urine tests with a shorter detection timeline.
• Hard to deceive: Hair drug tests are tough to cheat, ensuring more reliable results.
• Historical pattern: It reveals extended periods of drug consumption data, not solely recent use.

Limitations:

• Inability to gauge recent consumption: Drugs take about 5-7 days to appear in hair.
• Expense: Hair drug tests typically cost more than other testing approaches.
• Result variability: Results can be influenced by hair color and personal growth differences affecting drug metabolite concentrations in hair.

Note: Often referred to as "hair follicle tests," actual analysis determines content within the hair strand, not the follicle under the scalp

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Byrdstown, TN proves superior to urine testing with its extended detection period. Unlike urine tests, hair analysis can uncover drug use up to 90 days prior, offering a more thorough assessment of an individual's habits.

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.
