Hair Follicle Drug Testing - Choudrant, LA

What it is, How it works

Hair analysis has emerged as an effective mechanism for detecting drug and alcohol usage. Hair retains a comprehensive history of alcohol and other substances by embedding biomarkers within the fibers of the hair's growth. When collected from the scalp's proximity, hair can reveal up to an approximate 3-month window for alcohol and drug detection. Hair collection is straightforward, somewhat challenging to tamper with, and easy to send for testing.

A 1.5-inch segment, around 200 hair strands (resembling the diameter of a #2 pencil), nearest to the scalp yields 100mg, which is the optimal amount for testing and verification. For EtG, additional testing, and/or examinations exceeding 10 panels, a specimen of 150mg is advised. We suggest weighing the sample on a jeweler’s scale. Should scalp hair be inaccessible, an equal portion of body hair may be utilized. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

Drug testing in a laboratory encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the start of embedding a sample into a lab's system. This step verifies the proper sealing and shipping of the sample, assigns a random Laboratory Accessioning Number (LAN), and finalizes any remaining data entry not completed by an electronic chain of custody system.

Screening is an initial rapid assessment for drug presence. Although Screening is cost-efficient for eliminating drug use in most samples, positive screens need subsequent confirmation for court validity. Any samples presumed positive during Screening must undergo another confirmation process.

Should a sample indicate a presumptive positive during Screening, additional hair is extracted from the primary specimen and readied for Extraction. Here, drugs are extracted at markedly lower concentrations from hair than other methods (e.g., urine or oral fluid), which renders hair drug analysis the most complex testing method.

Any positive outcomes from Screening are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are pre-washed if required before confirmation. The complete lab procedure, from Accessioning through Confirmation, adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation guidelines.

Advantages of hair drug testing:

• Extended detection: Hair drug tests identify drug usage for up to 90 days, as opposed to urine tests with a narrower timeframe.
• Harder to falsify: Cheating a hair drug test is notably challenging, thus increasing result reliability.
• Offers past-usage insights: It depicts a history of drug use over time, not solely immediate usage.

Limitations:

• Inability to spot recent usage: A duration of 5-7 days is required for drugs to become detectable in hair.
• Expense: Hair drug analysis is typically costlier than other testing methods.
• Inconsistent results: Variances such as hair color and individual growth rates can impact the drug metabolite concentration in hair.

Note: While often termed "hair follicle tests," the actual analysis examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
