Hair Follicle Drug Testing - Pleak, TX

What it is, How it works

Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended track record of substance use by embedding indicators in the fibers of the hair as it grows. When harvested near the scalp, hair can reveal evidence of alcohol and other substances with a detection span of up to about 3 months. Harvesting hair is straightforward, relatively resistant to manipulation, and easy to transport.

Gathering a 1.5-inch portion of around 200 hair strands (akin to the girth of a #2 pencil) proximal to the scalp provides 100mg of hair, which is the optimal amount for both screening and validation tests. For EtG, supplementary testing, and/or evaluations exceeding 10 panels, 150mg of the sample is suggested. It's advisable to measure the sample on a jeweler's scale. If scalp hair is not available, an equivalent quantity of body hair is an acceptable substitute. When mentioning head hair, it pertains exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The drug test laboratory workflow includes four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning signifies the initial step of entering a sample into a lab's system. This step entails ensuring the sample was appropriately sealed and transported, assigning a LAN (Laboratory Accessioning Number), and completing any supplemental data entry needed beyond an electronic chain of custody setup.

Screening is the initial rapid assessment for drug abuse. Although Screening offers a cost-effective approach to dismiss drug consumption for most samples, any positive screening result requires confirmation to be legally acceptable. Samples deemed tentatively positive in Screening necessitate additional confirmation.

In cases where a screening stage suggests a positive result, additional hair is extracted from the original sample and readied for Extraction. During this phase, drugs are isolated from hair at significantly lower levels than other methods (such as urine or oral fluid), underscoring why hair drug testing is exceptionally challenging to conduct.

Verification of any positive screening outcome is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to validation, all samples with presumptive positive results are washed as needed. The entire procedure, from Accessioning through Confirmation, undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug consumption for as long as 90 days, unlike urine tests which offer a more limited window.
• Challenging to manipulate: Hair drug tests are notably difficult to falsify, enhancing the reliability of the results.
• Chronological data provided: It offers insight into patterns of drug use over time, beyond just recent activities.

Limitations:

• Inability to detect recent usage: Drugs typically become apparent in hair approximately 5-7 days post-use.
• Expense: Hair drug tests generally incur higher costs compared to other testing modalities.
• Result variability: Differences in hair attributes, such as color and growth rate, can influence metabolite levels in hair.

Note: Commonly referred to as "hair follicle tests", the analysis targets the hair strand itself, 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.
