Hair Follicle Drug Testing - Taft, OK

What it is, How it works

Hair analysis has increasingly been acknowledged as an effective method for identifying drug and alcohol consumption. This involves embedding biomarkers within the strands of hair, offering a prolonged history of substance use. When obtained near the scalp, hair samples can offer an approximate three-month period of detection for both alcohol and various drugs. Collection is straightforward, tampering is relatively challenging, and transportation is uncomplicated.

To obtain an adequate 100mg hair sample for analysis and verification, a 1.5-inch segment containing roughly 200 hairs, akin to the thickness of a #2 pencil, is required from the scalp. For tests such as EtG or over 10-panel screens, 150mg is advisable. It's best to measure the sample using a jeweler's scale. If scalp hairs are unavailable, equivalent quantities of body hair can be collected. The term 'head hair' is strictly related to scalp hair, while 'body hair' encompasses all other hair types (such as facial or axillary hair).

Process Overview

The laboratory sequence for assessing a drug test result primarily includes four stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to entering a sample into a lab's protocol, ensuring correct sealing and shipping, assigning an arbitrary LAN (Laboratory Accessioning Number), and filling out supplementary data not captured by an electronic custody chain.

Screening denotes a preliminary, swift assessment for detecting substance abuse. Though Screening provides an economically efficient means to negate drug use across most samples, court admission necessitates confirming any positive results. Samples presuming positivity in Screening mandate a subsequent confirmation.

For samples testing presumptively positive during Screening, additional hair from the initial sample is extracted for the Extraction phase. During Extraction, drug isolation from hair occurs at notably lower concentrations compared to other techniques (such as urine or oral fluid), which contributes to the increased complexity of hair drug analysis.

Confirmation of any positive Screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples undergo washing prior to necessary confirmations. The entire lab procedure, spanning Accessioning to Confirmation, undergoes scrutiny per both the CAP (College of American Pathologists) Hair guidelines and accreditation consonant with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug analysis can identify substance use over a period extending to 90 days, surpassing the shorter detection timelines associated with urine tests.
• Immunized against tampering: The test's design makes it exceedingly difficult to manipulate, thereby enhancing result reliability.
• Provision of usage history: It offers insight into patterns of substance use over time, not merely recent consumption.

Limitations:

• Lacks capacity for recent use detection: It requires approximately 5-7 days post-use for substances to become evident in hair.
• Expense: Generally, hair drug analysis incurs greater costs compared to alternative testing methods.
• Result variability: Drug metabolite concentrations in hair may vary based on factors like hair color and unique growth rates.

Note: Commonly called "hair follicle tests", the process actually examines 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.
