Hair Follicle Drug Testing - Tarrant, AL

What it is, How it works

Hair analysis has emerged as a formidable means for detecting drug and alcohol consumption. By embedding biomarkers within the fibers of the growing hair strand, hair offers a prolonged overview of alcohol and other substances. Hair closer to the scalp can reveal alcohol and drug use for nearly a 3-month period. Its collection is straightforward, slightly tough to tamper with, and effortless to transport.

A 1.5-inch segment with roughly 200 hair strands (similar in thickness to a #2 pencil) closest to the scalp yields 100mg of hair, which is ideal for both screening and verification. For EtG, additional analyses, and/or tests exceeding 10 panels, a 150mg specimen is advised. It's advisable to use a jeweler’s scale for weighing the specimen. Should scalp hair be unavailable, an equivalent quantity of body hair may be used. When we specify head hair, we refer solely to scalp hair. Body hair, on the other hand, includes all other types (facial, axillary, etc.).

Process Overview

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

Accessioning pertains to the preliminary integration of a sample into a lab’s system. This step checks that the sample was appropriately sealed and dispatched, assigns it a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody setup.

Screening is the initial brisk evaluation for substance abuse. Though cost-efficient in ruling out drug usage in most samples, a positive screen mandates confirmation for court admissibility. Samples flagged as potentially positive in Screening necessitate further confirmation.

If a sample is flagged as potentially positive in the Screening phase, additional hair is extracted from the original specimen for the Extraction phase. This stage involves extracting drugs from hair at significantly lower concentrations than in other methods (like urine or oral fluid), making hair drug screening one of the most intricate methodologies to undertake.

Confirmation of any potentially positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as potentially positive are cleansed before confirmation if necessary. The entire lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can sense drug use for up to 90 days, whereas urine tests have a more limited detection window.
• Challenging to manipulate: Cheating a hair drug test is exceedingly difficult, enhancing result accuracy.
• Historical evidence: It delivers a timeline of drug use over an extended period, rather than just recent use.

Limitations:

• Inability to detect recent consumption: It requires approximately 5-7 days for drugs to become traceable in hair.
• Expense: Generally, hair drug tests cost more than other drug detection methods.
• Result variability: Aspects like hair color and individual differences in hair growth may impact the drug metabolite concentration in hair.

Note: Commonly misnamed as "hair follicle tests", the assessment focuses on the hair strand, 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.
